This is not too uncommon. What tripped the breaker in your house also got to one of the relays on the logic board of your opener. The only cure I know of is a new logic board.

Why does the overhead light on my garage door opener go off & on without any reason, day or night, even when door is not in use?


There's a gremlin living in your overhead light.....lol. The circuit board in the opener has the timer for the light. There's a component that's beginning to fail on it. Replace the circuit board.

Craftsman overhead garage door opens at random?


There is some interference created by other wireless devices within range of your garage door. This maybe a door bell, baby motor or car immobilizer. Check to see if there are any new wireless devices, it maybe someone Cole by like a neighbor. Alternatively, you can delete the existing remotes from the unit and reprogram the remotes again, this will reprogram the emotes on a different frequency and hopefully cut out any interference.

Car garrage door opener


smart or learn button is located on the back of the garage door opener. (the machine that is over your head) on most units such as liftmaster, craftsman, chamberlin. its on back or side by the light bulb and is green, yellow, orange/red, purple. genie units are black button behind light cover. or external on old units. push and hold your cars homelink button will blink slow, at the same time push and hold the remote for the garage door. led light in car will blink fast. let both go. now go to the garage door head unit, (overhead) and push the learn button. button will blink and you have 30 sec. to go to car and push the cars garage door button. head unit should flash its light, letting you know that it is programed succesfully. genie units push 3 times

It sounds like a logic board problem to me. I would remove the board and look for bad connections especially around that small transformer.

Garage door opener won't open garage door


Remove the cover and take a look at the drive gear. It sounds like it is stripped.

Door won't open


Unfortunately storms do bad things so door openers sometimes. It has most likely gotten to your logic board. You can remove that board and look for burnt or missing traces of the print. Random flashing of that LED is normal.

My garage door opener does not work may have beem electrical storm. unit has power model 248739


I have Sears Craftsman model 139.58778 and the remote is suddenly not working for no apparent reason. The transmitter in the garage works fine but the portable unit for the car does not. The red light goes on and the toggle switches are correctly set and match the overhead unit setting. Any ideas what is wrong? I purchased a new remote and it did not work either after being correctly set, Thank you!
