I have a problem refrigerators not cooling, change the temp control the new one does the same thing. You can tap on the control it will run until it gets cold then shut down and will not start back. until you tap on it again.
Answer Hello Dennis. If that is happening, then the wiring in the unit going to the control is bad. Look for loose or bad connections on the unit. If all is good, see if the timer is sticking on the unit. If so, replace the timer.
where is the defrost timer located in the fridge
Where the controls are in the refrigerator section, you would remove that panel and the timer is located behind it.
