Hello,
I have a Maytag plus side by side and I am troubleshooting a cooling problem on the fridge side; freezer is at -15 degress while the fridge is at 55 degrees.
I suspect the evaporator fan, but to keep everyone clear is the evaporator fan in the freezer and the condensor fan under the outside of the refrigerator???!!
Please advise me... Thanks!

Problem sounds like a lack of air circulation between freezer and refrigerator. Make sure that all vents are clear and not blocked by food items..

Thanks Harold,

The return flapper is clear and I think the cold air supply at the top of the fridge side under the light assembly and temp controls.
