Help! We lost power and now the keypad and indoor pad don't work. I reset the the entire unit. All the remotes work but the unit continually blinks 3 times. Anyone have any suggestions? Thanks
The LED flashing 3 times is the code for a shorted wall switch. You can try removing the wires that go to it at the motor unit. They are connected to terminals 1 and 2. One of the wires has a red tracer. That is the one on terminal 1.
