My refrigerator goes on and off very often, sometimes several times a minute. Is there some control besides the main thermostat that could cause this? I don't here the big click like when the main thermostat goes on and off.
Answer Hello Jim,
I would check the start relay on the compressor to see if it is bad. Normally when you pull the relay off and shake it against your hand, there might be particles of ceramic that come out. If this happens then you would need a new relay. We would need to verify your refrigerator model number to help further. Please post your model number with a new question on the parts page. http://www.appliancepartspros.com/modelnumber_locator.aspx
My refrigerator does not defrost.
Answer Hello John. 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
