by Mike

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,

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.

Thanks Shawn. after posting I did turn on the fridge and left the cover off to see if the coils would freeze and I did see the defrost heater kick on and defrost the coils so I think the heater is... I will check the Thermostat and look into the defrost control. Thanks for your help !!!
