Refrigerator #RTT1700DAM (it's older) the ceiling of the fridge freezes up every 4 weeks or so leaving the fridge too warm. The freezer is fine. I have already replaced the defrost timer. I unplug the fridge to defrost the buildup and it works fine for another 4 weeks ect.

Is the compressor kicking on at all?

when you open the freezer door do you hear the fan blowing?all that happens is the evaporator coil in the freezer gets cold,the evap fan blows the cold air from the freezer and into the fridge side,there are ducts on the bottom left side where the air return sto the freezer,if that's blocked the fridge will get warm,also if the fan is blowing depending on your model you could have a damper,it's in the fridge section up top where the cold air blows into,all it is is a door that opens and closes to let the air in when the fridge section gets warm and then it closes when it's cold enough,if the damper is bad it won't open and let the air in,sometimes it gets stuck in the open position and things start to freeze in the fridge section.if you can't figure it out send the model number and i can see what model you have,open the fridge door,look up on the right side near the ceiling and you should see a tag with the model number.good luck and have a great weekend.also from the bottom up in the freezer,remove the second bin of food and touch the back inside wall of the freezer,if there's frost or like snow on the back inside wall of the freezer you have a defrost problem,let me know what you find.

if your freezer is working your fridge is fine
Your problem probably started a couple weeks ago when the drain that allows defrosted ice (water) to drain into the drain pan at the base of your fridge became plugged for some reason. Then everytime the fridge went on defrost more water melted but did not drain which in turn froze. Now ice has built up and caused the air that flows into the fridge to be blocked, causing a warm fridge.... my advice is to leave fridge unplugged for 48 hrs to thaw it and find the cause of the water not to drain... could be a corn niblet or pea from the freezer... the tube should be visible from the inside or the back

ok first of all. the refrige is in the basement. do you know what the relative humidity in the basement is?

you can check this with a humidity gauge.

Try defrosting freezer, sometimes when the defrost thermostat fails it causes ice too build up behind the walls of the freezer then it restricts the air flow to the refer side. If it works after defrosting then you probably need to get a new defrost thermostat.

it is almost certainly a defrost problem. when fault has occured, remove freezer bzck panel and see if there is ice build-up. if so this confirms a defrost problem - possibly that the element is open circuit
