Bruce for Model Number ziss480drbs Freezer randomly goes up form 5 F to 24 F, stays at 24F for 24 to 36 hrs. then goes back down to 4-5 F. Compressor is only hot during the draw down of the temperature - as hot as 138. What's wrong? Thanks
Answer Bruce, You will want to check the condenser fan motor to make sure that it is running. Make sure that the condenser coils at the top are clean. You will want to test the thermistors in the unit. The resistance of the thermistors should be 42.2k ohms at 0 degrees, 14.4K ohms at 37 degrees and 5K ohms at room temp of 77 degrees. If not within range then replace the thermistor. Read More... Answered by AppliancePartsPros.com | Wednesday, October 22, 2014
