I have maytag rsd2200eam side by side fridge. Fridge side had been getting warmer over a week now.. I cked airflow vents were free of ice.. Cleaned out fridge and freezer found ice on lower back wall of freezer and the evaporator coils frozen pretty solid.. But while emptying freezer I did find a piece of plastic blocking about 80% of bottom grate vents in bottom of freezer. I defrosted coils completely and plugged in again.. Took off perfectly and two days later good temps on both sides ( I have not put much back into either side of fridge/freeze yet). Took off freezer panel after two days and all coils are clean, just a little frost on bottom four rows of tubing behind/thru coils.. How long do I let it run to see if it freezes over again? Could the plastic have been blocking the air flow enough to cause the evap coils to freeze over? Or is it still the defrost cycle? If so is there a way to check if (1) defrost timer, (2) defrost thermostat, Or (3) defrost heater is faulty by myself?

I'd give it another week before trying more repair. 80% blockage by the plastic was more than enough to cause the freeze up. Air must be circulating to be effective.

I have the same refrigerator with the same problem. It's 13 years old now. I too, found the coils frozen over. I defrosted the unit and it worked fine again for about twelve days, but now I am back where I started, with 50 degree refrigerator temps. The cooling coils are once again frozen. I tested the defrost timer and it seems to work fine. What am I left with the defrost thermostat and defrost heater? How do I check them?

Jalute, what was the end result of your problem please?

Thank you,

Mike

I found the problem myself. It was the defrost heater element. It was physically broken at the bottom of the cooiling coils that were frozen over. The coiled heating element is housed inside of a glass tube. The tube cracked, water got in, and the element failed. This is a very cheap fix, just plug in two wires on the new one. Ebay is your friend.
