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.
My matag ref. ices up and the ref comp is warm.
Answer Hello Jack. It sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the evaporator coils in the freezer. If so, you will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
