Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
I have tried eliminating other frequency problems - such as CFC light bulbs
Have you tried making sure you don't have motion detectors on light by the door. This will sometimes cause trouble when the sensors are going bad or if you have cfc or led bulbs in them.

Actually Jeffrey, since your opener isn't human, it can't possibly know whether it's day or night, so the problem lies elsewhere. You don't say how close you are to the door you are. My opener is older and very touchy and doesn't always respond when pushed because the contacts are worn. Try this, take the opener off your visor. turn it
face up and then see if it works. If it does, its time to get a new opener. First make sure the battery's good. Hope this helped, Ken

Thoroughly check all the connections. temp changes might effect connectors.
