The above model dryer is a very nice condition electric dryer with a peculiar circumstance . After it shuts off from a drying cycle it will about an hour or less later start to chirp at the control board area. The LED 's will also blink. It does not do anything drastic but it will continue this chirp noise. If I push the stop button it will stop but later start the chirp noise again. Does anyone have any experience with this type of problem ?
