Cathy B. for Model Number Hotpoint HSM25GFTC Coil in freezer is a block of ice. Changed out control board ,defrost element still a block of ice. What next before I blow it up?
Answer Hello Cathy. Test the heater WR51X10055 and the thermostat WR50X10068 on the coils. They should read closed for continuity when cold. if both test good, and the entire assembly of coils are ice, you will need to replace the thermistor WR55X10025 located on the top of the evaporator coils. 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 Read More...
