How do I get the old thermostat out of the refrigerator?
There should be a screw that holds the housing for the thermostat in place. Remove the screws and the cover and disconnected the thermosat. Install in reverse.
The evaporator builds lots of ice.very often. I have to turn off the refrigerator, melt the iceand then it will work fine for few days. couldit be the defrost termostat?
Answer Hello Joe. It sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the back wall of 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
The defrost timer is not cycling. I replaced the timer and it's still not cycling. Does anything else need to be looked at? I've also replaced the heater and the defrost thermostat. This didn't help. Any help on what to look for now?
Answer Hello Kenneth,
I would look for the wiring diagram on the unit, (probably on the back), and use a test meter to insure voltage is getting to the timer motor. If it is, look on the other side of the defrost timer for the neutral side of the circuit.
