David for Model Number TFX20JRBKWW Temp. in refrigerator/freezer gradually getting warmer even on the highest setting of cold. Back of freezer wall is frosting up. Could this be cold control or defrost control panel? or both or something else. Originally noted items frozen in refrigerator a couple weeks ago.. then reversed and everything is spoiling . We now have both emptied and need to fix asap.
Answer Hello David. Based on the information you provided, it sounds like you have a defrost problem. You will need to test the defrost heater and thermostat WR51X10031. They should read closed for continuity when cold. If both of these are good, you will need to replace the defrost timer WR9X489. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
