Despite their unwavering reputation for convenience and durability, Liftmaster garage door openers can occasionally malfunction, even with proper maintenance. This can happen at the most unexpected time, leaving you stranded with a garage door that is stuck open.
If your Liftmaster garage door won’t close, closes halfway or partially, then reverses, buckle up as we take you through some effective troubleshooting tips to get your garage door back up and running.
Liftmaster garage door won’t close
Failure to close your Liftmaster garage door despite multiple attempts can be a nerve-wracking ordeal. However, garage doors are heavy, and we tend to use them frequently; hence, occasional breakdowns hardly news, especially if the door has served you for a long time. Therefore, rather than fretting, consider stepping back from the situation to analyze the cause of the problem systematically.
It could be anything ranging from a mere spider web obstructing the sensors to a faulty roller throwing the door off balance. Fortunately, the solution is often a DIY process, provided you establish where the problem lies.
Here is a breakdown of how to go about the most common causes of your Liftmaster garage door not closing:
Power outage/Disconnection from the power source
Accidentally disconnecting your opener from the power source is a common occurrence. Before focusing on more complex mechanical issues, it is essential to start with the basics. Check whether the opener’s power cord is intact and the power outlet is functional. You can try connecting a different electric device to the outlet to confirm whether it’s operating effectively.
Otherwise, the problem could be caused by short-circuiting, primarily due to socket overloading. Short-circuiting could also be the culprit in the event of a sudden power outage. In such cases where electricity is involved, the ultimate solution is to seek technical intervention to enhance safety.
Dead remote batteries
Simple as it seems, replacing your remote’s batteries could easily save the day. However, before blaming the remote, ensure you’re using it within an appropriate range. More importantly, eliminate nearby devices that could interfere with the remote’s signal. Otherwise, the ultimate solution would be to reprogram the remote. But before you do so, ensure you confirm that the remote is the culprit.
Fortunately, the Liftmaster garage opener graces you with the privilege of operating the door using either a remote control or a wall console.
Consider closing the door using the wall switch to check whether it will be responsive. If the switch is functional, check whether the lock mode is active; if not, it’s time to replace the batteries.
Misalignment or blockage of the safety sensors
Liftmaster garage openers come with safety sensors fitted on either side of the garage door. These sensors are so sensitive that even the tiniest of debris can cause them to trigger the door’s reversal. Although the competence of the sensors comes in handy in guaranteeing the safety of garage users, it can be a nuisance if the sensors keep triggering the door to reverse even when there is no visible obstruction.
You can confirm whether the problem lies within the sensors by checking whether the sensor LED light is flickering. If this is the case, ensure you eliminate any obstacle in the doorway and wipe the sensors to remove any dust particles or tiny debris that could be interrupting the sensors’ beam of light.
If the flickering persists, check the alignment of the sensors to establish whether they are on the same level. You could measure the distance from each sensor to the ground to ensure it’s equal. If not, re-align the sensors, and the garage door should close effectively.
An activated LOCK button
The LOCK button is among the outstanding elements of Liftmaster garage openers. This button guarantees your garage door’s safety even when you are away on vacation. Activating the button disconnects all remote controls and prevents intruders from accessing your garage.
Despite its convenience, unconsciously activating the button will disable your remote control, preventing you from opening or closing the garage door. You can confirm if this is the problem by checking whether the command LED on the door control is flashing. Flashing indicates that the LOCK button is active.
In this case, identify the LOCK button on the door control and press it for two seconds until it stops flashing. Once the flashing stops, you should be able to close the door using your remote control effortlessly.
Inaccurate travel limit settings
The DOWN travel setting determines how far down the garage door travels. Therefore, if the door closes partially or travels too far down, the limit settings could be off. If the door closes partially and then stops, you may need to increase the DOWN limit so that it travels further down.
With the help of your manual, identify the DOWN travel adjustment screw and rotate it counterclockwise. Each rotation increases the DOWN travel by two inches. Repeat the process until the door closes sufficiently.
On the other hand, if the door closes then reverses automatically even without obstructions, consider decreasing the DOWN travel. You can turn the screw in a clockwise direction until the door closes adequately without reversing. More importantly, ensure you test the efficiency of the safety sensors after adjusting the limit settings.
Misalignment or obstruction of the garage door track
If you have an old, heavy-duty garage door, expect dents and bending of the tracks occasionally. Failing to lubricate garage door parts could also leave you with old garage door rollers that can throw the door off balance. A noisy garage door most likely features a track with blemishes.
You could start by cleaning and lubricating the rollers and other garage door parts so that the door closes smoothly. Subsequently, assess the track to identify any bends or defective screws and bolts. Follow up by replacing defective brackets or screws on the track. Loosen the screws once you identify the misaligned parts of the track and straighten them out using a level and rubber mallet. Finish up by re-tightening the screws, and the door should close smoothly.
Broken Torsion Springs
Like most garage door parts, torsion springs require replacement following years of use because they feature a limited number of cycles. Defective torsion springs can make it difficult to open or close your garage door. You can establish if the springs are the culprit by checking if the door is uneven or if the springs are sagging.
When the springs break, they snap and give off a loud pop sound that’s impossible to miss. Torsion springs bear the weight of the garage door, and fixing or replacing them yourself is dangerous. Therefore, in this case, it’s best to reach out to an expert for safety purposes.
Still unsure of what to do?
When push comes to shove, close the door manually. Before you do so, ensure the garage doorway is clear to prevent accidents. You can then disengage the door by pulling the emergency release cord downward and towards the opener. This way, you can manually open and close the door as you seek technical assistance.

Liftmaster garage door won’t close yellow light
A yellow light on your garage door sensor indicates an interruption of the sensors’ beam of light, and there should be no cause for alarm. The sensors’ primary purpose is to prevent accidents by reversing the door if there’s an obstruction in the doorway. They do so with the help of an infrared beam that runs from the sending to the receiving safety sensor.
Interruption of the beam, even by a tiny dust particle, will cause the sensors to malfunction, which explains why the door won’t close. Alternatively, garage users might unconsciously knock the sensors out of place, causing misalignment. The proximity of the sensors to the floor subjects them to constant exposure to grime and debris.
Therefore, you will want to start by dusting off the photo eyes, preferably using a wet cloth or paper towel, while ensuring it’s not too wet. You can even go in with a mild cleaner to remove stubborn stains. If the yellow light persists, you may use a level to check the alignment of the sensors.
In cases of misalignment, loosen the bracket or wingnut (depending on your specific model) that holds the sensors in place and adjust them accordingly until they are on the same level. The garage door should then close as usual. If not, check the sensor wires, which tend to fray following prolonged use and harsh weather.
If you notice any significant damage on the wires, then it’s time to leave it to the experts. Attempting to fix sensor wiring problems can be hazardous, and reaching out to a professional is advisable to avoid compromising your safety.
Liftmaster garage door won’t go down
A Liftmaster garage door that won’t go down must have encountered a blockage on one or more parts, preventing closure. The blockage could be in the track, torsion springs, or sensors.
Attempting to close your garage door using the remote control only for it to stick can be frustrating. When this happens, the first thought that probably comes to your mind is that the remote batteries are dead. But what if you try closing the door using the wall control instead, and nothing happens?
Before you reach out for repair services, try to identify where the obstruction lies through the steps below to save some coins if possible.
Check the Safety Sensors
Once you rule out the basics, including no power supply, a defective remote, or dead batteries, an obstruction of the safety sensors is the most probable cause. Therefore, ensure you clear the doorway by removing all obstacles, including items close to the sensors.
Follow up by cleaning up any debris on the lenses that could be blocking the photo eyes. More importantly, check if the sensors are level and realign if necessary. Most Liftmaster opener units tend to flicker in the event of sensor misalignment, which should give you an idea of what you’re dealing with.
Check the Track and Rollers
If your garage door is old, expect it to go off the track, especially with poor maintenance. In this case, check the track for bends or misalignment and straighten them out with a rubber mallet. Be sure to clean the track if there is debris accumulation. Finish off by lubricating the track and rollers; the door should go down smoothly without sticking.
Check the Emergency Release Cord
The emergency release cord disengages the door from the opener, preventing you from operating the door automatically through the remote control. You can confirm if this is the case by attempting to close the door manually. If you succeed, you may want to re-engage the door to the opener by pulling the cord downwards, away from the opener. In this way, you may resume operating the door automatically.
Adjust the Travel Limits
You may have to increase the downward travel when the door doesn’t go down. All you have to do is locate the DOWN travel adjustment screw and rotate it counterclockwise using a screwdriver.
Doing so increases the distance through which the door travels so that it reaches the ground. However, avoid excessively increasing DOWN travel because the door will go too far down and reverse as though it has encountered an obstruction.
Check the Torsion Springs
The torsion springs comprise a lot of tension; therefore, it comes as no surprise when they occasionally break following intensive operation. Common signs of broken torsion springs include sagging and unbalanced garage doors.
If you suspect torsion spring breakage, consider seeking repair services because attempting to fix the springs yourself can be detrimental.
Contact the manufacturer
Once you establish that the above garage door parts are intact, yet the door still won’t go down, you may want to reach out to the Liftmaster support channel. The same applies if you identify the source of the problem but don’t know how to disassemble some parts to fix the problem.
Trying to fix the problem yourself while you are unsure of what you are doing could exacerbate the situation or end up voiding the warranty. You will get step-by-step guidance on troubleshooting your specific opener’s model by contacting Liftmaster. Even better, you may not have to incur the repair cost unless the manufacturer advises otherwise.
Liftmaster garage door won’t close in cold weather
Extreme cold weather conditions can numb your garage door, impairing its functionality. For starters, garage doors feature a weather seal at the bottom. The sole purpose of the seal is to prevent gaps through which rodents, dirt, or water can pass and infiltrate the garage. During cold weather, while the weather stripping bars snow or water from passing through, water can freeze around it, causing the door to stick.
Accumulation of snow beneath the garage door could obstruct the safety sensors, preventing the garage door from closing. Therefore, consider constantly eliminating snow and water puddles near the garage door to prevent them from accumulating near the sensors.
Apart from obstruction of the sensors, the door could be jamming due to the contraction of the metal parts. These include the track, rollers, hinges, and torsion springs. Contracted rollers, for instance, could stick and prevent the door from navigating the track smoothly. You can resolve this by lubricating the door’s moving parts, preferably using silicone lubricant for best results.
Cold weather also causes grease to harden and build up, which could be a reason for the door not closing. You can dissolve the grease using solvent, then wipe it away and lubricate the garage door parts to get the door back up and running.
Contraction of the track during cold weather could also cause bends and dents, causing the door to stick. If you identify any bends on the track during cold weather, you may want to reach out to a professional to avoid damaging the track.
Liftmaster garage door won’t close just clicks
Signaling your garage door to close only for the opener to produce a clicking sound without doing anything else can be frustrating. The click sound signifies that the door is receiving a signal from the remote but is simply unresponsive.
This could be due to various factors, most of which you can resolve yourself. These include:
Issues with the safety sensors
These can be anything ranging from an interruption of the sensor beam of light to improper wiring of the sensors. Automatic garage openers can barely operate if the safety sensors are defective. A clicking sound can, therefore, signal that the sensors are malfunctioning and the door won’t close for safety reasons.
Be sure to dust off the sensors, remove obstructions from the doorway and re-align the sensors. The sensor wiring could also be faulty, and if this is the case, consult your manual and re-wire the sensors accordingly for accurate results.
Direct exposure of the sensors to sunlight can also compromise their sensitivity. Too much sunlight can prevent the receiving sensor from perceiving the infrared beam emanating from the sending sensors. In this case, consider installing a guard to shield the receiving sensor from the sun’s rays. You may want to inspect other garage door parts if these fail to remedy the situation.
Faulty springs or rollers
Springs and rollers have a limited lifecycle and are most likely the culprit when your garage door becomes defective. Consider checking for any corrosion of the rollers and lubricate or replace them if they are faulty. Damaged springs can compromise tension, causing the door to click without any movement. If you suspect you have a broken spring, reach out to a professional to avoid putting yourself at risk.
A defective circuit board
If you live in an area that experiences frequent power outages, your garage opener is more likely to experience a short circuit. Inside the motor unit is the circuit board, which integrates the opener’s components. Short-circuiting due to a power surge can easily damage the circuit board, preventing the motor unit from functioning correctly, hence the clicking sound. The ultimate solution is to replace the circuit board with the help of a professional.
How do you align a garage door sensor?
Garage door safety sensors are one of the door’s most crucial parts. They are usually found about six inches off the ground on either side of the garage door and communicate through an infrared beam. Any slight distortion or knocking of the sensors out of place will cause them to malfunction due to misalignment.
The sensor’s adjacency to the ground increases the chances of unconscious distortion by garage users. Liftmaster models usually have diagnostic error codes that help you tell if the sensors aren’t in line. In some models, you will see the upward arrow flashing four times and the downward arrow flashing six times, indicating that the sensors aren’t on the same level. Other models will convey the same message through the LEARN button LED on the opener unit, which will blink four times consecutively in ten-second intervals.
Fortunately, restoring the functionality of the sensors is a DIY process that could only take a few minutes. Each Liftmaster model is unique, and although the procedure may vary slightly, here are some steps to guide you through.
Identify the receiving sensor
The receiving sensor usually features a green LED light that glows steadily if the sensors are level. Upon misalignment, you should see the green LED light on the sensor flashing continuously. In some cases, the LED could be off or faint.
Unfasten the wingnut or bracket
Once you locate the sensor, unfasten the wingnut using your hand to loosen the sensor. The wingnut holds the sensors in place in many latest Liftmaster models, while others feature a bracket instead. If you’re dealing with a bracket situation, you’ll need a screwdriver to loosen it.
Adjust the sensor
Upon loosening the wingnut, the sensor should now be moving freely. Adjust the receiving sensor until its green LED lights up and becomes steady, indicating that the sensors have re-aligned properly.
Test the safety sensors
After adjusting, you have to operate the garage door in the presence of an obstruction to ensure the sensors are functional. You will want to open your garage door, place an object underneath it, and then signal the door to close. If the sensors are effective, the door should automatically reverse once it comes into contact with the obstacle.
Liftmaster garage door won’t open with wall switch
Experiencing a situation whereby your Liftmaster garage door operates normally using the remote control but won’t respond to the wall control is pretty common. A defective Liftmaster wall switch usually exhibits a green flickering LED; if this is the case, you will have to open it up to diagnose the problem.
Start by detaching the wall switch by unscrewing it using a screwdriver. While at it, note that the culprit can either be the switch itself or its wiring. Once the unit is out, identify the two wires that usually lie inside and try connecting them. If the motor fails to run and the door doesn’t open, the wires are faulty, and the unit needs rewiring. It is always advisable to leave matters electricity to a professional, meaning you will have to seek repair services if this is the case.
Otherwise, if the motor runs upon connecting the wires, you are most probably dealing with a defective wall switch and will have to get a replacement. In worse-case scenarios where the problem may persist despite replacing the wires or the switch itself, you may have to replace the logic board with the help of a professional.
Why is my Liftmaster wall button not working?
The Liftmaster wall button serves as an alternative to the remote control. Even though a defective wall button won’t prevent you from operating the garage door, it is essential to have a functional remote control and wall button in case one of them fails. The wall button may fail due to three main reasons which include:
These are common in old garage doors with poor maintenance. You can confirm if the problem lies within the wires by removing the wall button and connecting the two wires underlying it. If the opener still fails, it means the wires are faulty. If this is the case, you can even identify some punctures on the wires upon assessment.
A faulty wall switch
If manually connecting the wires together resolves the issue, then the wall button itself could be faulty. Unfortunately, in this case, the ultimate solution would be to install a new wall button, and you’ll be good to go.
A broken circuit board
The circuit board is probably the culprit if the wall button fails following a power outage. The logic board can be subject to short-circuiting if you experience frequent power outages. The best way to go around a broken circuit board is to replace it.
Frequently Asked Questions
Q1. What does orange light mean on garage door sensor?
Unlike the receiving sensor, which displays a green LED, the sending sensor usually exhibits an orange indicator light. The LED on both sensors should glow steadily when the photo eyes are in alignment. On the other hand, a flickering orange light on the sensor indicates a problem with the sensor wiring.
You might also notice that the green LED on the receiving sensor is off or flashing. Assess the sensors’ electrical connection from the sensor itself to the terminal on the opener unit. You might notice some fraying on the wire that could hinder the sensor’s connection to the opener.
Q2. Liftmaster garage door clicks but won’t open
A Liftmaster garage door that has stayed closed for a long time is more likely to get stuck either due to accumulation of debris or ice during winter. When this happens, consider the following remedies:
- Ensure the security lock on the wall pad is off, so it doesn’t override the remote’s commands.
- Consider melting ice and removing accumulated debris to unstick the door and ensure the photo eyes are clear.
- Check for any bent parts on the track or worn-out rollers and repair them.
Q3. Liftmaster garage door won’t open after power outage
When you experience a power outage, your Liftmaster garage door won’t be able to operate the door without a power supply, and this is where the emergency release cord comes in. You will have to unplug the opener and disengage the door from it by pulling the cord downward towards the opener unit until you hear a clicking sound.
You should then be able to open and close the door manually until power is restored. When the power is back, plug in the opener and pull the emergency cord toward the door. If the door fails to open, you are most likely dealing with a faulty logic board, and you may have to call a professional to look at it.
Q4. Liftmaster garage opener won’t close light flashes
Encountering a flashing Liftmaster garage opener that won’t close could be due to two main reasons: Misalignment of the safety sensors or an activated LOCK button.
