I have an Amana Refrigerator Model # ARB2202CC Freezer on the bottom. the coils keep on freezing up causing the fridge to warm up. after thawing the coils it freezes up after about a week again.

The defrost heater has a defrost limit thermostat ( a small disc with two wires) that is attached to the cooling coil. This defrost limit thermostat is a switch that will open when the coil is warm enough after defrost. If the defrost heater is staying on too long it can create steam which will condense and freeze on the vents after defrost period terminates.

On your model your cntrl board has a relay that can stick causing the compressor to always run even when the unit is turned off or in defrost. turn the fridge off, move the temp of the freezer to it's warmest setting and it should display a line in the freezer and fridge temp display. listen to hear if the compressor is running in back of the unit. if it is you need part number: 12868513

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

The refrigerator half of a refrigerator/freezer does not produce any cold! The refrigerator is cooled by transferring air from the freezer to the fridge. The fridge temperature setting controls a flapper between the freezer and the fridge. There should be a fan which blows air from the freezer into the fridge (through the damper).
If the ice forming in the freezer is concealing the cooling coil and air can not move through the coils, then the overall result will be a warm freezer (even though there may be ice in one location) and a warmer yet fridge. This can be tested by unplugging the fridge and allowing a complete thaw. If the ice is the cause of the problem, then it should work for a short while until it freezes up improperly again

Hi,

Many times a freezer and/or refrigerator do not work right because of a dirty condenser coil...there are also many other things that can go wrong.

If you are hearing a clicking or buzzing then check out the last two tips.

If your refrigerator is running but warm, then...

Check out these tips that I wrote about that... it is a great place to start trouble shooting your unit...and something that you can do rather then calling a repair person to do a simple thing for you...

This is a defrost problem most likely caused by a defective defrost thermostat. It is located in the freezer compartment behind back wall on top right hand side of coils and usually has a brown and an orange wire connecting to it. It should have continuity when checking with a volt/ohm meter when it is frozen and read open when it is warm.
I have seen many of the newer electronic temperature model bottom mounts with defective control boards as well that cause the fridge to skip the defrost cycle.
Good luck!

I had a similar problem where my evaporator coil was freezing into a block of ice, which caused my fridge to warm up due to a lack of air flow. I fixed this by doing a few things. I replaced the circuit board ($100) which was easy to do. Unfortunately, this didn't fix my problem so I took the inner fridge cover off to view the evaporator/heater coil assembly. I checked my thermo fuse and found it to be open (failed). I ordered the thermo fuse and the thermistor and replaced them both. I then plugged the fridge back up and put a regular thermometer inside the fridge to get an accurate reading of inside temp. A few days now and everything looks good. The board, fuse, and thermistor were all pretty easy to replace.

either compressor is jammed or the starting relay with capacity is faculty

just called in a sears technician 150 dollar bill that was an easy fix. he says my bottom freezer kenmore fridge with warm fridge problem was due to the pathway being blocked by ice and garbage which is common with these fridges. he took off cover from the fridge bottom and poured boiling water down to the freezer. try that before you replace any parts or call in a tech. next time im getting a top freezer because the blower is on the top not in the middle with the bottom freezers and thus more problem prone.
