Challenger 9300 Model CH-1000
(Ft. Lauderdale, FL)
My garage door opener works fine when I use the remote, but nothing happens when I use the push button switch on the garage wall. I took the push button out of the wall and tested it with a continuity tester, and the push button switch is good. Do you have any suggestions? Thank you.
You may have a broken wire between the wall control switch and the power head (motor assembly). Check those for continuity and for possible broken wire that may not show on your tester without moving the wires about. The wires, if broken, usually have a fault near staples.
Also check the connections at both ends. Loose or corroded connections can cause problems.
