My 3 year old Genie Garage Door Opener (screw type) will now only close if I hold the wall button down for the entire travel. It will open from the remote control but not close using it. This, combined with the fact that the right hand (looking from inside) infrared unit LED is very dim (always used to be bright, and blinked if obstruction present) leads me to believe it's that unit. The left IR unit has a solid bright LED. Wiring seems to be fine. It's been really cold this winter, I suspect frost or cold damage.
My questions: - Anybody have experience with this kind of problem? Diagnostic suggestions? I can't find the owners manual (of course). I have rudimentary electronics knowledge (volt meter stuff, nothing fancy). - Two home centers near me (you know the ones) offer everything but replacement IR units. Any suggestions for on-line sources to consider (or to definitely avoid?) - I gather defeating the unit is a bad idea or not practical. My young- est child is 19 but, granted, it might save my car trunk someday.
Thanks in advance for reading this and making any suggestions!
