I have a 139.53xxx garage door opener. There was lightning strike in the neighborhood and we lost electricity. Upon restoration of power, we found the GDO to be inoperative. Observations:
- When one pushes either the wall button or a remote, there is a click from the GDO whereupon the light goes on and nothing else happens. No hums, nothing.
- The light goes out after a few minutes as it should.
- Blocking a sensor and trying again leads to the GDO light blinking, so that part of the system is working.
- The light on the wall button is on at all times.
- There is a little green light on the back of the board that I think has to do with the remote control. It blinks intermittently.
I'm thinking that something got fried inside the GDO. A new circuit board is $80 + shipping, which is a significant fraction of the cost of a new one. I did notice a big capacitor inside wired between the power coming into the device and the motor. I suspect it is there to give a shot of juice get the motor going when the button is pushed. It looks OK from the outside. At $18 or so it is worth replacing if this indeed is the trouble. Any ideas?
