I have a side by side MAYTAG MZD 2768 GE the fridge part is not getting cool enough anymore. Everything else is fine- The crisper fans are not running Would those fans cause the fridge not to get cool enough?

Clean the coils and condensing fan. Usually. This will cause unit to run warm

It was the circuit board in the upper part of the fridge. Put new circuit board in & fridge is getting colder now.
