Question About Chamberlain Garage Door Opener Power Drive
garage door opener beeps every 15 sec....

I have a Chamberlain Whisper Drive, model 940D-01 Security + wireless keyless entry. I have had it about three years now. Works fine. This past Saturday the unit started beeping every 15 sec and a red light is lite. Does anyone know the meaning of this?
