I have an 8 year old Maytag french door refrigerator which has been troublesome for the past 5 years ago. It started with the ADC failure. I replaced the evaporator fan motor and jazz board and bought a surge protector. Last year the duck bill drain plugged leaving water on the floor and giving the box a "bladder control issue" according to my daughter. Whirlpool sent a free p trap replacement. This weekend it again developed the cold freezer and warm fridge symptom. There was modest frost build-up in the freezer, but not as bad as 5 years ago when I replaced the control board. I followed the Samurai’s advice and put it into forced defrost mode and could hear the condenser fan continue to run, so I thought the ADC/Jazz board needed replacement again. I continued the rest of the troubleshooting steps to make sure that there were no other bad parts and low and behold the evaporator fan began blowing cold air into the fresh food compartment. The fresh food compartment has cooled, but I'm not sure if the coils will completely defrost after a few days or if I need to turn the box off and let the ice all melt off. I'm also not sure if the fix is permanent or if it will frost up again and I will eventually need to replace the ADC/Jazz board again! Any advice appreciated!
