Troubleshoot common garage door opener issues including power, sensor, remote, travel limit, and motor problems.
What You Need to Know
1) Check Power and Lockouts
Confirm outlet power, breaker status, and wall control lock mode. Many no-run events are simple power or lock settings.
2) Inspect Safety Sensors
Clean sensor lenses, verify both indicator lights are on, and realign if blinking. Misalignment often blocks closing.
3) Verify Remote and Keypad
Replace remote batteries, reprogram if needed, and test wall control separately to isolate transmitter issues.
4) Review Travel and Force Settings
If the door reverses unexpectedly or stops short, travel and force settings may be out of calibration and require adjustment.
Need Professional Help?
For safety-critical issues or uncertain diagnosis, schedule a professional inspection before forcing operation.
