This video from Sears PartsDirect shows how to troubleshoot motor and travel problems with your garage door opener. On the type of motor unit that has a single LED light, the light will flash 5 times to indicate one of these problems: garage door travel is obstructed, garage door opener trolley is obstructed, motor is overheated, motor RPM sensor is defective. On the type with up and down arrows, the up arrow blinks once and the down arrow blinks 5 times to indicate the same set of problems.

1. Let the unit cool
If you've just used your garage door opener several times, allow the motor to cool for 30 minutes. If the garage door opener works after a half hour, it’s likely the motor overheated from repeated use.

2. Reset the logic board
If you haven't used the door recently, or your door still won't open 30 minutes later, unplug the garage door opener for 1 minute to reset the logic board. Then, restore power and try opening the door again. Resetting the logic board may fix your problem.

3. Check the track and door latch
Pull the emergency release rope to disconnect the garage door from the trolley. Open and close the garage door manually. If the door doesn’t move at all or sticks in some areas, check for a bent door track.

Also, make sure the door latch retracts fully. If the latch gets locked accidentally or it isn’t fully retracted, the door won’t move.

4. Check the rails and trollies
If the door travels easily on the tracks, a bent or damaged garage door opener rail could be blocking trolley travel. Check the rail for damage and replace any damaged parts.

If you see no apparent rail damage, check the inner trolley travel along the rail. Activate the garage door opener to move the inner trolley along the rail in one direction and then activate it again to check the opposite direction. If the inner trolley stops along the rail and you find damage, repair it, or replace the rail. Also, take a look at the inner trolley and replace it if you find any damage.

5. Repair the RPM sensor
If the inner trolley only moves 6 to 8 inches and you don't find any rail damage, replace the motor RPM sensor because it isn't detecting motor speed.

6. Repair the logic board
If the indicator light flashes 6 times, the motor unit detects an internal motor circuit failure. Replace the logic board because the motor rarely fails.
