John for Model Number 106.53652300 Freezer coil was frozen. Thawed refrigerator and replaced thermostat. Would not cool after that. Replaced new thermostat with old one and initially would not cool. Unplugged and replugged it a few times after waiting from one hour to a couple of hours. All of a sudden coils were frosting up. Unplugged to replace with new thermostat and replugged to discover it was not cooling again. replaced new with old thermostat and still no cooling. Waited a couple of hours and opened the freezer to discover coils were frosting up again. Unplugged for a couple of minutes to tape up wire connections and leave old thermostat wired in. Plugged back in and discovered it was not cooling again. Prior to replacing thermostat the only problem I had was that it would freeze up . Now it doesn't want to cool at all. I thought about replacing the defrost timer and the start relay but not sure what to do at this point.
Answer Hi John. The defrost thermostat part # WPW10225581 can be tested by inserting it in a glass of ice water. After a few minutes it should be a closed contact. Test it with a ohm meter and it should read 0-ohms (closed). It also has to open at a certain temperature (approx.45°) to be considered to be good as well. If you purchased the thermostat from us we will stand behind it 100%. Unfortunately as it don't happen hardly at all a man made electrical device can be bad. It also sounds like a loose wire as well because of movement in and out of the system or in moving the unit. Are the fans and lights going when it is not frosting up ? The control board sounds defective part # 8201527. If it does start up and frost builds up then the sealed system is working. If you are hearing a heavy audible click every few -to- 30 seconds by the compressor then by all means the compressor relay part # WP4387835 or the compressor windings are an issue. Make sure the condenser coils are clean so the cond.fan does its job well and you are not boiling the freon. Thank You. Read More... Answered by AppliancePartsPros.com | Friday, May 18, 2012
