Common Causes of Flashing Lights on Garage Door Motors
Flashing lights on garage door motors are usually designed to notify users of issues that need attention. Below are the common reasons why your garage door motor light might be flashing:
1. Safety Sensor Issues
Garage doors have built-in safety sensors to prevent accidents or damage. These sensors, typically located on each side of the door near the floor, communicate with each other to detect objects or obstacles in the door’s path. If these sensors detect an obstruction, they will signal the motor to prevent the door from closing, which often triggers the flashing light.
How to Identify a Sensor Problem
- Check for Obstructions: Look around the door for any objects that might block the sensor. Even small items can disrupt the sensor’s function.
- Inspect Sensor Alignment: Misaligned sensors will not communicate correctly. Check if they are facing each other; most sensors have an indicator light that should be steady when properly aligned.
- Clean the Sensors: Dust, dirt, or cobwebs can cover the sensors, preventing them from detecting obstacles. Use a soft cloth to gently clean each sensor.
If you need assistance with your garage door sensors, Garage Door Repairman serves Calgary, Okotoks, and Airdrie. Our professionals can realign or replace faulty sensors, ensuring your door operates safely and effectively. Visit Garage Door Repairman for more information.
2. Problem with the Logic Board
The logic board in your garage door opener is like the brain of the system. It controls all functions, including opening, closing, and signaling errors through the flashing lights. If the logic board is faulty, it may cause the light to flash as a warning.
Identifying a Logic Board Issue
- Inconsistent Operation: If the garage door works intermittently or behaves unpredictably, this could indicate a problem with the logic board.
- Flashing Patterns: Different opener brands use various flashing patterns to signal specific problems. Check your garage door opener manual to interpret these signals.
- Power Surges: Power surges, especially after a storm, can damage the logic board. Consider installing a surge protector on the outlet used by your garage door opener.
Replacing or repairing a logic board requires technical skills. If you suspect a logic board problem, call Garage Door Repairman for expert assistance in Calgary, Okotoks, or Airdrie. Schedule a repair at Garage Door Repairman.
3. Low or Dead Battery
Some garage door openers are equipped with a battery backup system. If the battery is low or dead, it may cause the motor light to flash, signaling that the battery needs attention.
Checking and Replacing the Battery
- Battery Indicator: Many modern garage door openers have a battery indicator light. Check the light’s color, which may signal a low or depleted battery.
- Replace the Battery: If the indicator light shows a low battery, open the battery compartment and replace the old battery with a new one.
Regular battery maintenance ensures smooth operation of your garage door opener. For more information on maintaining your opener, reach out to Garage Door Repairman, proudly serving Calgary, Okotoks, and Airdrie.
4. Remote Control Malfunctions
Sometimes, the flashing light may be related to the remote control rather than the garage door opener itself. If the remote malfunctions, it may cause the light to flash as the motor tries to process the signal.
Diagnosing Remote Control Problems
- Check Battery: Replace the battery in your remote if it hasn’t been changed recently. Low battery power can lead to signal issues.
- Reprogram the Remote: In some cases, reprogramming the remote control to the garage door opener can resolve issues.
- Interference: Electronic devices such as LED bulbs, routers, or other wireless devices can interfere with remote control signals.
If you experience persistent issues with your remote control, contact Garage Door Repairman to troubleshoot and resolve remote control issues for garage doors in Calgary, Okotoks, and Airdrie.
5. Wiring Problems
Over time, wiring can become loose, frayed, or disconnected, causing the garage door opener’s light to flash. Loose wiring may also interfere with the door’s operation, creating a safety hazard.
Identifying and Fixing Wiring Problems
- Inspect Connections: If you’re comfortable handling electrical components, check for loose or frayed wires in the opener.
- Consult a Professional: If you see exposed or damaged wires, it’s best to consult a professional to avoid electrical risks.

6. System Needs to be Reset
In some cases, your garage door opener simply needs a reset to clear minor glitches or issues. Resetting the system can often resolve flashing light issues.
How to Reset Your Garage Door Opener
- Consult the Manual: Your garage door opener manual should have instructions on how to reset the system. Most resets involve pressing and holding specific buttons on the opener.
- Unplug and Replug: Some issues can be resolved by unplugging the opener, waiting for a few seconds, and then plugging it back in.
If resetting does not solve the issue, the problem may be more complex. Contact Garage Door Repairman for help in diagnosing and repairing your garage door.
