Craftsman Garage door opener
Hi, I have a Craftsman Garage Door Opener model 139.53990D. about 2 yrs old. The remotes and the key pad stopped working. The button inside the garage works fine. I tried reprograming the key pad and remotes according to the instructions but the unit did not respond like it was suposed to ie. the garage lights flashing when the codes were "learned". I tried the proceedure several times with the same result(didn't work). I also ckecked the sensors and wiring to the sensors and the all seem to be ok. I think it may be the logic board. Any other ideas?
