Maytag fridge model # MFF2557HEB

try disconnecting thermistor and let run if ok replace it if no possible low on freon

Sounds like one or more of ofvyour 3 defrost components have failed which are defrost heater , defrost thermostat, and defrost timer or board

Can you feel air moving or hear the fan running in the freezer section? You said the freezer section is freezing well, but is it freezing really hard?

all it does is the freezer gets cold,the evap fan blows cold air from the freezer into the fridge section so if the freezer is fine,check the air ducts in the fridge section,if a package or something is blocking the vent on the bottom it will get warm or also on your model you have a damper on the top where the air blow into the fridge section from the freezer,you have an electronic damper,there's a door that opens and closes to let the air in,when it's cold enough the door closes when it gets warm the door opens so either the damper is bad or the computer board that operates it is bad,also check the packages in the freezer,if you see frozen water droplets on the packages or ice on the shelves the door could have been left open and the air ducts freeze so no air can pass through,you can hit the air ducts with a hair dryer to melt them out but be careful,don't keep the heat on one spot for to long,you can damage the ducts,also when you open the freezer door you should hear the fan blowing,if not you could have a bad evap fan motor and the air isn't blowing over to the fridge section,the damper is like 45 dollars and the computer board is around 120 dollars,you can go onto the sears site,put your model number in and look at the controls and you can look up the parts.http://www.searspartsdirect.com/partsdirect/part-model/Maytag-Parts/Refrigerator-Parts/Model-MCD2257HEB/3048/0165000/M0703130/00006?blt=06&prst=&shdMod= copy and paste.open the freezer door,listen for the fan no fan bad motor,if the fan is blowing either the air ducts are frozen or you have a problem with the damper or board that operates the damper,you might want to call in a tech for this if it is the damper,it's a little tricky to do this job but that's up to you.good luck and i hope this helps you out.

all that happens is the cold air from the freezer gets blown into the fridge section by the evap fan motor brhind the inside back wall of the freezer so if you open the freezer door and don't hear the fan blowing i would say that yes you do have a bad evap fan motor and that's why the fridge section is warm.next time send the brand name and model number so i can help you better

Hi,

Many times a freezer and/or refrigeratordo not work right because of a dirty condenser coil...there are also many otherthings that can go wrong. If you are hearing a clicking or buzzing then check out thelast two tips.

I had similar problem in that the fan in the freezer that blows freezing air into freezer and over to fridge was not working. Fridge was running warm (over 40 deg and freezer up near 20) Service call around $160 with new fan.

You should try to clean the coils under the fridge . Thats a simple thing to try .If your fridge /freezer cant remove the heat it wont cool ,also please make sure your doors are closing tight. We can start on all the free things you can try first..

it is almost certainly a defrost problem. when fault has occured, remove freezer bzck panel and see if there is ice build-up. if so this confirms a defrost problem - possibly that the element is open circuit
