What would cause the ice to melt then the water to refreeze.
Answer Hello Doug. It could be the cold control sticking or the defrost timer sticking on the unit. You will need to check both parts on the unit.
For several years my freezer evaporator coil would freeze up and refrigerator would stop cooling. So I would defrost it and it would go back to working fine for several months. In the past few months it freezes up in a few weeks. I thought I would change out the bi metal thermostate but decided to ask you first. thanks
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
