Maytag mff2557hew fridge not cooling. Freezer ok.

Yes it has a fan you should here it and feel it. It sounds like your defrost coil may have gone out. Take the back pannel of the freezer off and see if it is clogged with frost.

Clogged coils can cause poor cooling. Check to make sure nothing is stuck in the condenser fan and that it spins freely (models with coils on the back won't have a fan). To do this, unplug the fridge and pull it out. Clean the fan blades and spin the fan by hand to see if it's stuck.

Fan in freezer working? Any frost build up on inside back freezer wall?

Possibly evaporator fan not working or defrost problem.

Some fridge freezers take the cold air from the freezer and moves it into the fridge via small duct in the back of the inside of the fridge and freezer . Empty frige and freezer , take plug ouy of wall and carefully remove involved panels taking note of any mechanical valves and order for reassembly. Clean and clear all airways and check for any blockages . Over loading of freezer can also obstruct airways . Whilst you are doing this you will allow a good defrost time for fridge and freezer airways . Hope this helps

The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. Make sure this fan is running. The fan should spin freely when you spin it. You can check the fan plug for voltage to see if it's getting power with the door switch pushed in. You may have to hold the door switch in for it to run. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp.
The problem could be the electronic control if you have one or the mechanical linkages.

If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it'll be the control.

Low on freon or there may be accumulation of dust and dirt on the coils of the condensor. To check to see if the coils are dirty you need to remove the bottom panel of the fridge just below the frige door. Once you pop off this panel take a flashlight and look under the unit. You will see what looks like a radiator with a fan and fan motor in front of it. If these coils are blocked the unit will not cool since this is where the heat goes from the fridge to be dispersed. Clean the coils with a coil brush (purchased at any hardware store) and use a wet/dry vacuum to remove the debris. Once these coils are cleaned it will take about 12 hours for the unit to operate properly.
If the coils are clean already then you possibly have a compressor that is low on freon. I would check the coils first since most of the time this is the cause of the problem.

Good luck on your repair hope this helped you some

i am not a expert just trying to help,,, try pulling fride out and checking the line from freezer down to the pan and made sure it is clear,cause this will keep the air from flowing,, hope this help

sounds as if perhaps the fan in the freezer is not circulating air up to refrig sect. pretty common issue, if you pull out freezer door youll be able to hear the fan on the back wall, behind the vent on top sect of freezer. that cover pops right off with a pry of the screw driver.. heres the part number if indded that is the issue 12002744 comes with instuctions on how to install

3 thingsto check. If you didn't adjust the damer from the freezer to the refrigerator, like closed it off. Is the freezer fan running. The fan blows air from the freezer to the refrigerator section. Some fans shut off when the door is open so you may have to push in the door switch to check this out.
Look for ice on the back wall, of the freezer section, if present then the defrost cycle is not working. The evap. coil is icing up and there is no air into the refrigerator.
