How to Troubleshoot & Replace Frigidaire AP6892591 / 134523200NH Electronic Control Board

Cleaned moisture sensor, especially the accumulated lint at the terminals/wiring, inside the airduct. Replaced the control board. Apparently, the new control board is slightly different version; so some diagnostic steps wouldn't apply, otherwise okay. 

Simple troubleshooting showed that the control was behaving erratically. Replaced the control. 

I ordered the control board one day and got it the next. I replaced the board and the problem was solved. 

I researched the model on YouTube where the majority of videos indicated the constant beeping, was due to the failure of the control board. I ordered a replacement from Appliance Parts Pros. I replaced the failed board, and it now works fine. Easy fix!! 

Replaced the control board after checking the discharge duct, limiters, thermistor, motor. Works like new. Thank you for the very FAST DELIVERY, next day 

Replaced the control board. 

Replaced control circuit board. 

Replaced the control panel. YouTube video showed how from start to finish, although I probably could have figured it out myself, but would have taken a lot longer and involved some swearing. 

Replaced the motherboard. 

Tried to release switch but no luck. Ordered and replaced control board.
