Fridgidare Top Freezer-FRT22TSE-The evap coil on freezer freezes up within 5-10 min. What do I replace, the defrost thermostat, heater and/or something else?
Answer Hello Keith,
If the coils are freezing up that quickly, you need to make sure the evaporator fan motor is running. If it doesn't run, the coils will freeze up from the top to the bottom, (the top first). Otherwise, you should be looking for the moisture that is getting into the area such as a stopped up defrost drain. The coils should not freeze up that fast. The fan motor is the first suspect.
Give me information so I can get access to the defrost heater for replacement of the heater.
Answer Hello William. If you unplug the unit and remove the back wall inside the freezer, you should be able to access the evaporator coils and the heater. You will need to pull out the evaporator just enough to remove the heater, but be careful not to break the heater in the unit. The heater should read closed for continuity. If it reads closed, it is good. 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
