The refrigerator section of our 19-year old refrigerator suddenly started freezing the food. Freezer section also seems to have gone hyper-cold. I have replaced the bimetal defrost thermostat (Whirlpool 4387503) and the defrost timer kit (EAP376605), but this has not helped.
The control knob works, as when switched to OFF the box will turn off.
ANSWER Hello Dave. Based on the information you provided, the temp control 1123394 is bad and will need to be replaced. It is not reading properly and is allowing the air in the unit to get to cold before shutting off.
