Our freezer started defrosting. Sounds like the motor is still running but everything is melting in the freezer. The fridge compartment is working well. How should we troubleshoot?
Make sure all the fans and compressor is operating. If one is not then this is the problem...All fans must work inside and outside. If after you have verified this is not the problem UNPLUG THE UNIT and look at the freezer rear lower wall. You are looking for frost. If you find frost you will need to shut it off and open it up for 24 hours. Unscrew the lights so they don't stay on. The next day you are going to need to remove that panel with the frost on it to access the coils and defrost any remaining frost. Clipped onto the coils is a disc shaped object about the diameter of a quarter with 2 wires coming out of it. This is the defrost thermostat. If you have a meter you can verify that this part is good by allowing it to get very cold..(frosty) and then see if you can read through the 2 wires..get a reading cold its good,,,no reading cold,,,its bad. At the bottom of the coils is the defrost heater,,,look at it good if it looks ok then take the meter and see if you can get a reading through that. Same as the defrost thermostat except it does not need to be cold. Get a ohm reading its good. The last part is the defrost timer. I do not know where it is located on your unit it could be anywhere but I do know this. If the other 2 parts are good and you did have a lot of frost on your coils then this is the bad part. You will need to locate it and replace it.
