Curt for Model Number rt188kxjw00 Fridge was not getting cold in lower part, freezer working fine, found ports that allowed cold air from freezer to come into lower compartment clogged with ice, removed rear panel on inside of freezer and found fan was working but the coil was frozen almost solid. Can you help me find what might be causing this and help me fix it ? Thank You for your time
Answer Hello Curt. 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 Read More...
