The photo eye is out of alignment.
If a garage door fails to close properly, it may be necessary to adjust or realign the safety sensors. Located at the bottom of the door track on either side, these sensors, often referred to as electronic eyes, need an unobstructed view of each other. When the sightlines are clear, the door should close completely to the ground. However, misaligned brackets that hold these sensors can prevent the door from fully descending. Typically, the door will either halt or reverse, accompanied by flashing lights to indicate an issue. To resolve this, manually adjust the safety sensors or their brackets to ensure a clear line of sight between them.
The photo eye is contaminated.
Occasionally, the sensors may be obstructed by leaves or debris, preventing the garage door from closing properly. Check to ensure that the area between the two electronic sensors is clear. Carefully clean the eye section of each sensor, taking care not to disturb their alignment.
The garage door remote or keypad is malfunctioning.
If a garage door fails to open, it’s possible that the wireless remote or the installed keypad has ceased to function properly with the opener.
- If the door operates using the hardwired wall switch, the issue may lie with the battery of the remote control or keypad, which may need to be replaced. If the battery is in good condition, check to make sure the loose wire antenna on the motor unit is hanging down properly and is not damaged.
- Resetting the remote control: It might be necessary to reconfigure the remote control or keypad. The delicate electronics within these devices can occasionally become unsynchronized and require a reset. Since the reprogramming process can vary between different garage door openers, it’s advisable to refer to the user manual or search online for instructions tailored to your specific brand.
- Examine the lock: Additionally, inspect the door from within the garage to confirm that no one has manually secured the garage door from the inside.

Garage door rollers might require some lubrication.
A downward-moving garage door can occasionally have trouble opening, particularly during the winter months. Cold temperatures can cause the rollers to become rigid, resulting in the door opening sluggishly or not opening at all.
- If you encounter loose screws or issues with the sensitivity of the opener, check the motor unit for a screw that allows you to modify the sensitivity settings. Since the adjustment techniques can differ, refer to the owner’s manual for specific instructions.
- Lubrication: Applying lubricant to the rollers can assist in addressing this issue. Opt for white lithium or silicone-based lubricants, as they are less likely to clump or gather dirt.

It might be necessary to replace the rollers on your garage door.
Corroded or broken rollers may lead to the door getting stuck in the tracks, preventing it from opening properly. To resolve this issue, you can either replace the faulty rollers or apply silicone or white lithium grease to them. When rollers are damaged or rusted, they can increase friction, causing the door opener to halt unexpectedly. To avoid this situation, it’s important to keep the rollers in good condition and properly lubricated.
The motor of the garage door opener is disconnected from the power source.
If the garage door does not respond when the remote or wall switch is activated, it is likely that the power supply has been interrupted. Often, the motor unit may have become disconnected. Over time, plugs can become loose, and the movement of objects in and out of the garage can inadvertently pull the cord out of the outlet. Verify that the cord is securely plugged into the ceiling outlet where the door opener is connected.
The power supply to the garage door motor has been interrupted.
If the cord for the garage door is connected, it’s possible that the circuit breaker, fuse, or GFCI outlet that supplies power to the door opener has either tripped or failed. If you notice that other lights or electrical systems in the garage are also not functioning, this is probably the reason. You will need to either reset the breaker or GFCI, or replace the defective breaker or blown fuse.
Tip
If the circuit breaker or GFCI keeps tripping, it indicates that there may be a short circuit within the system, which could potentially involve the garage door opener.
The upper limit switch should be relocated nearer to the motor.
If the garage door opens only partially and fails to reach the fully open position, the up-limit switch, typically a touch lever located at the end of the track near the motor, may require adjustment. If the switch is positioned too far from the motor, the door will halt before fully opening. To resolve this issue, the switch should be repositioned closer to the motor unit. This uncommon issue typically arises right after a new garage door opener is installed.
