Craftsman 1/2 HP GDO stopped working

I have a 1/2 hp Craftsman GDO, which is probably older, maybe 15 years or so. This morning I pushed the button inside the garage and it opened up just fine. When I got in my car and pushed the button, nothing happened. So, I tried from the panel on the outside, still nothing. When I went inside the garage and pushed the button, I heard a "humming" sound - like power was going to the unit and trying to operate it but no movement whatsoever. I checked to make sure the track was clean, no obstructions to the sensors, manually opened and closed the door several times but it's the same thing, just a power humming for a few seconds.

Could the motor have given out that quickly? As I said, it opened the door just fine but then wouldn't close it. The light doesn't "blink" off and on like there's a problem. In fact, the light comes on just as it should, then goes off after a minute or two - just as it should. I unplugged it and then plugged it back in to no avail.

Is it expensive to have someone look at it, and who would I call anyway? Sears? It's long past warranty to be sure.

Any thoughts or suggestions?

It sounds like it could be the start capacitor or the drive gear. The cost to repair if you can't DIY is almost the price of a new unit less installation. It's a hard call.

Sounds like your logic board might be going on the fritz. If you think you might want to replace it yourself, I can tell you where NOT to buy it. I recently bought one from Ontario Supply in New York from their web site for $60. Unfortunately, it has turned out to be defective and they won't refund my purchase price even though I sent the defective unit back at my own cost. So, don't buy from them, they don't deal fairly in my opinion. I think you're best off just calling a local repair service and let them replace the board. If you replace the board yourself and it does not work, you're just going to end up calling a repair service anyway. Ontario Supply operates under the following web sites:


In my opinion, you should avoid this company
