Same: Only wall button works

Remotes and keypad stopped working at the same time. Units is 5 yo. Reset remotes countless times, no change. Some people suggest it is the receiver, but I did not touch anything in the unit.

It is your receiver that is bad and is part of the logic board. The remotes and keypad send a signal that the receiver uses to switch the relay that controls the motor. The wall control is wired directly and doesn't use the receiver. The key is both the remotes and keypad quit at the same time.

Replaced batteries.changed codes verified not in lock position checked wiring-checked breakers -remotes dont work have 2 different units-one commercial all stopped working on same day -need help


I have the Same Problem...
2 similar but independent 315MHz Craftsman door openers stopped receiving any remote signals at the exact same time. One hour they worked , next hour they didn't, no storms in area.

I know remotes are good because they still open our subdivision gate. the Only way to open door is with wall pad. Verified that they are not on vacation lock. 5 different remotes, 2 different keypads all no longer open door.
I tried resetting codes with learn button but they won't take new programming. Also before when an unlearned remote was used in the area, the learn light would at least flicker (as if it was receiveng a code, but rejecting it) It no longer even does that.
i even cycled the circuit breaker and the vacation lock, no help.

Does anyone know how to fix this?

Genie remotes stopped working


The receiver can go bad and that would stop all remotes from working. The wall control would still work because it does not use the receiver.

All of a sudden all three remotes stopped working at the same time. Battery is okay, hard wire opener works


You probably have the lock enguaged on the opener. On the wall control, there is a button labeled "lock". Press and hold for 3 seconds and then release. the light on the wall button should be solid now. Your remotes should work. If the light is solid and the remotes still do not work, press the learn button on the back of the opener motor and then press the button on the remote. The light on the motor will blink once. Repeat on the other two remotes.
