Joe for Model Number tcx18pacbrww The refrigerator fan wll quit blowing in the ref unit and coils freeze over under bottom shelf. Unit quits cooling, freezer unit stays cold. ice maker is ok. We defrost coils with a hair dryer and it will work ok for a few weeks and then does it again. Is it the defrost time or control board?
Answer Joe, 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...
