Why is my fridge not cooling properly?
The sensor that tells the compressor to run is probably coated with ice or frost.When this happens the compressor wont turn on enough because the probe is still frozen, look for a small metal tube like a wire about 1/8" thick usually clipped close to the cooling plate. this needs to stay free of ice for the fridge to maintain temperature. don't use an Ice pick to chip the ice off because you may damage the evaporator coils and release the freon. It is best to turn the fridge off and let it melt, (food in a Ice chest) I have used warm water to melt the ice faster but this makes a mess also. I don't recommend hair dryers as there could be a shock hazzard with all the water. Hand held torches may damage the coils and plastic parts. Usually a bad seal on the door causes the excessive buildup.
