Why does the garage door light blinks but the door does not open?

There are several possible reasons for this issue:

1. The safety sensors may be misaligned or blocked: Most garage doors have safety sensors located near the ground on both sides of the door. If something blocks the path between these sensors or they become misaligned, the door will not open. In this case, the light may blink as a warning that the door is not able to close fully.

2. The door's travel limit settings may be incorrect: Every garage door has travel limit settings that tell the motor how far to open or close the door. If these settings are incorrect, the door may not open fully or may not open at all. The light may blink as an indicator that the motor is still trying to open the door but cannot.

3. The motor may be malfunctioning: If the motor is malfunctioning, it may not be able to lift the door to the fully open position. In this case, the light may blink as a warning that the motor is struggling to open the door.

4. The remote or wall switch may not be working: If the garage door opener's remote or wall switch is not working correctly, it may not send the proper signal to the motor to open the door. In this case, the light may blink as an indicator that the motor is not receiving the proper signal.

To fix this issue, homeowners should first check the safety sensors to make sure they are correctly aligned and nothing is blocking their path. They should also check the travel limit settings to ensure that they are set correctly. If neither of these solutions works, the motor may need to be replaced or repaired, and the remote or wall switch should be checked for proper functionality.
