Remotes for Sears 3/4 garage door opener working intermittently
A few weeks ago my remotes for the garage door opener started acting up. In the garage the remotes work fine, outside the garage they stopped working. If I get out of the car with the remote and reach into the garage it works and the door closes. The wireless keypad also now works sporadically. Most of the time it does not work. The hard wired connection to the opener inside the garage has always worked and still does. The 2 lights on the sensors for the door reversal are solid, and works fine if I ever break the beam when closing the door, it reverses like it is supposed to, and turns the light on when it is dark and the beam is broken.
Prior to a few weeks ago, the remotes worked 50-60 feet away from the door and worked perfectly. Suddenly about 2-3 weeks ago all of this started. The only change I can think of is excessive cold in my area. 10-20 below zero. Now it is about 30 above and it is still acting up. Any ideas? Should I reprogram all the remotes? Any input would be appreciated. Thanks for reading this.
