Which is the red wire connection?
Answer James, On this style thermostat 4-83053-003 it doesn't matter. The switch is a "single pole, single throw" (SPST) switch. When the cooling cycle is operating the switch has a "closed" circuit and supplies power to the compressor. When the temperature selected is reached the switch "opens" and removes power to the compressor until the cycle repeats.
Freezer keeps running until ice is on coils and there is no air flow.
Answer Hello Bobby. 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
