Hi

I have a Frigidaire FRS26TS7DW2...and this morning it stop cooling both freezer and fridge. The Water dispenser also did not work as well as not making Ice, once I unplugged and defrosted everything seem to work ok but not sure for how long.. since a few days ago everything in my freezer had frost. I opened up the cover and the evaporator coils where frozen...any ideas what it could be ? searching on line it's looking like a defrost issue but I would like some expert advice. any help is appreciated.

Hi Mike,

Replacement parts in FRIGIDAIRE FRS26TS7DW2 Frigidaire/refrigerator


If the coils are covered with frost there is a problem with the defrost system. On your refrigerator the defrost system is the defrost heater, defrost thermostat and the adaptive defrost control.
To tell which one is bad you will need an ohmmeter. First make sure there is some ice build up to ensure that the thermostat should be tripped. You don’t have to wait until the refrigerator stops cooling just a few days.
Turn off the refrigerator and take the back wall out the freezer. Unplug the defrost heater and thermostat. Using your ohmmeter test for continuity across the heater and the thermostat.

If you do not have continuity across the thermostat the thermostat is bad and needs replacing.




If you do not have continuity across the heater the heater is bad and needs replacing.




If both of these parts check out ok (have continuity) replace the adaptive defrost control.




I hope this helps!
