Question about Kidde Nighthawk Combo Gas/co Detector
I keep getting an error code when plugged in
I have the same problem....The answer is the detector has died. This kind of detector has a warranty for 5 years. Mine was assembled 8 years ago and just died this morning. 8 years is good for this kind of detector. The protection device inside wears out in time. Thats why you keep getting an err message.

Actually, it was a pre-planned detector death. See
These units expire automatically seven years after power up. Unfortunately this "feature" is only documented in for some models.
