Thank you for you recent answer. I just have additional info about the refrigerator. I took off the back panel and nothing is icing up. The fan and heater are working also. The fan by the compressor is working also. I took out the temperature control and was wondering if there is any way I can check the temperature control with a volt/ohm meter to verify it is bad, not that I doubt you answer.
Answer Hello Ed,
The cold control is a set of contacts that make and break as the temperature of the attached "bulb" dictates. In order to test it, you need to be able to control the temperature of the "bulb" so you can see what temperatures the contacts make and break. This almost requires a laboratory as controlling the temperature is the hard part. It can be done, but you have to know the "bulb" temperature at the precise time the contacts open and then when they close. Of course the contacts are checked with an ohm-meter, but just sticking the "bulb" in a glass of ice water isn't a precise test. The precise calibration is where the temperature "control" falls into play.
The refrigerator run continuously at the lowest setting. Is it the temperature control?
Answer Hello Ed. Yes, if the unit is freezing this and the only way to turn it off is to turn the control to 0, you will need to replace the temp control WR9X545. Hope this helps.
