The freezer side of our maytag side by side just stopped staying cold, the fridge part seems cool still but maybe not quite as much as before, you can still hear the entire fridge working, we took off the rear panel and cant notice anything out of the ordinary, out of ideas....its only like 4 years old so i'm hoping we are just looking at a quick fix....

Hi,
This is a common defrost problem, The ice
is not being melted by the defrost system. he fan can't blow into ref.
Take out back panel of freezer to check for icw build up. The coils should be clean.
There are three components to a defrost system- a heater,heater thermostat, and a timer unless you have a defrost electronic card.
Its best handled by a Technician but you could possibly do it by taking your model number to the nearest appliance parts store and asking for the parts. They are mostly located in freezer ,behind back panel on freezer coils.except the card which is usually located in ref The parts store will have info
Also check evaporator fan in freezer
Also check fan undernearh Ref in the rear
Clean condenser coils underneath
If this was helpful please rate me
Thanks for using fixya
