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!

You are going to have to find where you are losing power. The most likely place is the logic board especially if you have had any electrical storms or power surges. Remove the board and check for loose or missing traces on the printed circuit.

Chamberlain 1/2hp Operator won't work after electrical storm


Sounds like the circuit board got zapped. You could price a new board or take it apart and check the components if you know how, but normal mortals would just buy a new unit.

My garage door opener stoped working after a storm.


TRY TO REPROGRAM THE REMOTES TO THE OPENER - THESE UNITS CAN LOSE THE MEMORY DURING STORMS.

I WOULD SUGGEST ADDING A SURGE PROTECTOR AT THE PLUG IN TO PREVENT DAMAGE TO YOUR UNIT IN THE FUTURE.

Upon closer inspection I found that the power board had burnt. Weve had several power surges after the ice storm and apparently one weakend the unit. Price for the board (from craftsman) is like 80.00 and not knowing what else may have took a hit I replaced whole unit for 140.00.

Liftmaster 1/3 HP - humming, but does not open.


It's the gear drive. There are kits online for about $40, if you're semi-handy you can replace it yourself. Search for liftmaster replacement parts.
