Ned September 08, 2012 for Model Number FFU20FC4CWO We recently had the deforst timer replaced on this freezer (6 years old). now the freezer triggers the circuit breaker and turns off after 10-12 hours. When I turn the defrost timer past the two clicks it runs again and we have to do this avery 8-10 hours. What is the issue and can this be resolved with replacing the heater element? or something else?
1 Answer Hi Ned. Check the defrost timer connections to see if there is a shorted wire grounding out onto the chassis or the bracket mount. Open the freezer back wall and make sure the defrost thermostat part # 297216600 is closed (0-ohms) under normal temperatures. Make sure the heater part # 216730700 leads are not grounded out as well. Repair all terminal leads if necessary. The heater should have resistance and not open (o-ohms). From what you described the Defrost timer part # 5304518034 may have internally shorted terminals. Thank You. Read More...
Roy March 16, 2012 for Model Number frigidare freezer plfu1777ds1 The freezer coils develop frost in spring thru fall, in the winter they seem to be ok. Last year we changed the compressor for this problem. Now the problem is back with warm weather. Is there a solution to the build-up of frost that then ices up the coils?
1 Answer Hello Roy. The problem you are describing has nothing to do with the compressor but is a defrost issue. There is only a few components in this circuit: the defrost timer, the defrost heater, the defrost thermostat, and the wiring harness. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html The defrost timer 5304518034 is mounted behind the kick panel and has a knob that allows you to advance it into defrost. This is the first test. Advance the timer into defrost,(you will know it's there when the fan and compressor kicks off). It should advance itself out of defrost in 30 minutes or less. If this happens, the defrost timer is probably good. Now the next test you need to open the freezer back wall,(after unplugging the unit to prevent electrical shock), and ohm out the heater 216730700 and the defrost thermostat 297216600. Whichever part you find bad will correct the situation and it will once again be a self-defrosting unit. Have a great day! Read More...
Keith June 03, 2011 for Model Number FF2U0F9GW5 How do you test the heater element / defrost heater part to see if it still works?
1 Answer Hello Keith. You will test and see if the heater is closed for continuity. 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...
