Craftsman GDO wall unit light out, remote won't work
As many have written, my GDO car remote suddenly quit working. The exterior garage keypad and interior wall buttons work fine. There is no light on the wall unit pad. I have changed the remote battery and tried to check the vacation lock, but without the wall unit light I have no way of knowing if there is a communication. I tried to lock/unlock several times, so that should have fixed any lockout problem. Could the exterior keypad code be interfering with or overriding the remote? I recently purchased the home and have no manuals. Sears/tech support won't help, they quit offering tech support unless purchase was within 90 days. Please help!
Remote dated 06/06, verified it has the correct three blue buttons. It worked well for about 4 weeks.
Exterior Keypad: May be generic, don't know if it came with GDO.
