Would a defective defrost control cause the the refrigerator side to go up to about 50 degrees and stay there? If I unplug and defrost the entire side-by-side, and the refrigerator side worked for a few days and went back up to 50 degrees, what might that be symptoms of?

Automatic Defrost wont shut off and the frost crystals is being built up on the inside of the freezer walls. My worry is fire,the motor keeps running,doesnt shut off. Repairman is due Wed.4/16/14 but its 1 am and I worry about motor getting too hot and starts a fire. Do you feel I should unplug the entire thing?

I have a MSD2756DEQ Model Whirlpool Side by Side Refrigerator/Freezer. SN 10507386YH, installed in my home May 2000. In the last year I have had the refrigerator side shows warm on my refrigerator thermometer. Because of a similar experience several years ago, I learned from a refrigerator repairman to take the back panel in the freezer compartment off to look at the evaporator. I have done that and each time in the past year it has been coated with ice. Using a hair dryer, I have melted the ice off, put everything back and it works. A friend suggested it could be a problem with the defrost timer. I know there must be some sort of defroster mechanism also. How can I figure out on my own, what is wrong and what part to replace?

Latest Questions

I have a Whirlpool side by side model that cycles between having a moderately cold freezer compartment (capable of producing ice) and a not-so-cold refrigerator side. This condition persists even with the refrigerator indicator knob at its COLDEST dial setting. On some occasions the ice within the bin begins to thaw. At this point I disconnect the unit for a period of time and then reconnect it. This seems to do the trick until the thawing condition reappears. Where should I begin my diagnosis. I have basic tech skills. Thanks.

My refrigerator seems like it is stuck in defrost. Everything in my freezer has defrosted and it isn't making any noise.

On a adaptive defrost system does the polarity of the defrost thermostat matter? I checked the defrost heater and thermostat for continuity and they checked out fine. I installed a new control board but only the lights went on . Condenser fan did not go on. Sounds to me like defective board but what about the polarity question above. Thank you
