My Maytag (fridge over freezer) had a very warm fridge last night, but the freezer was fine relative to temperature.
I noticed a 1/4" sheet of ice on the back wall of the freezer, and took the cover/panel off to notice that the evaporative coils were solid frozen and caked with ice. A hair-dryer helped to melt the ice.
I put it back together and changed the fridge coolness setting to '7', the coldest.
Today the fridge is in normal temperature range.
I'm wondering if I still need to replace the evaporative fan motor ? or maybe the damper assembly?
Would defrosting the evaporative coils be potentially the only thing wrong?
Thoughts?

Here are your parts Parts for Maytag MBF2255KEB Refrigerator - AppliancePartsPros.comSee the attachment for the tech sheet [COLOR="Blue"]I'm wondering if I still need to replace the evaporative fan motor ?[/COLOR] If it was running it should be OK [COLOR="Blue"] or maybe the damper assembly?[/COLOR] I doubt it. [COLOR="Blue"]Would defrosting the evaporative coils be potentially the only thing wrong?[/COLOR] Yes. If the fan cannot pull air through the evaporator coils it will give you the symptoms you had. It sounds like you have a defrost problem. See the tech sheet for how to force a defrost cycle. When the fans and compressor go off you are in defrost. Check if the defrost heater comes on. Be careful that you do not burn your fingers. Also the defrost thermostat must be frozen for the heater to come on. It opens just above freezing killing power to the defrost heater. If it comes on you probably need a new control board as it is not programming defrost cycles when it should. If the heater does not come on. Unplug the unit. Check the defrost thermostat. It should be 0 ohms when frozen. If it is deformed/bulged replace it even if it does measure OK. Check the defrost heater, should be around 30 ohms. If both are OK then odds are that the control board is bad. |
