I had the same problem. When the evaporator heater stops working, frost will build up until there is no air flow to the refrigerator. This will cause the refrigerator to keep running. Remove everything from the freezer and remove the pan at the bottom and see if there is a frost buildup. .... Bruce

Refrigerator not cold but freezer freezing

The first thing you want to do is open the freezer and see if the fan inside there is running. The reason is the freezer cools the refrigerator side by circulating air from the freezer. If the fan is running then your problem is one or more parts of the defrost system is malfunctioned and in return your problem arises. There are three parts to the system, the defrost timer or in some cases control board, defrost thermostat also known as a bi-metal, and the defrost heater. The defrost system is set up to operate as so. The defrost timer or control board will turn the machine off, in some cases every 8 hours, some 12. During this time period the defrost heaters, located behind the freezer wall and rest underneath the evaporator, yet wires to them run up the side of it, are energized and emit heat that raises upward to melt the ice that has formed on the evaporator coils. The bi-metal or defrost thermostat is at the top of the evaporator. When the heat from the heater starts to reach the bi-metal, it breaks the circuit turning the heater off. The whole purpose of this is because the freezer cool the refridgerator side by drawing air across the coils and blowing to the other side via the evap fan motor. In my opinion, if you change one part of the defrost system change them all because usually when one part fails another will follow, so save yourself the time and the food loss, the cost difference is minute.

My refrigerator is not working properly.. the freezer section is work fine.. but the other section is not getting cold...I bought this refigerator six months ago...the model is .. MCBR1010W

Your complaint is not unusual, except that you say the frig is only 6 mo. old. First, I suggest you call the manufacture for warranty service since the unit is still new. There are several items that could cause this problem. It usually will not help by playing with the controls for frig & freeze; the unit should work properly with the controls set at normal midrange for both frig and freez; changing the settings from normal cannot compensate for a mechanical problem. is the refrig in an enclosed space that cannot get good air circulation, or does this frig have the black grid coil in the back and you have the frig up against the rear wall so that no air can remove the heat from this coil ? Any other cause would require mechanical work within the frig components.

Side by side freezer side not working all food was defrosted

When this happens, usually the frig side is also not so cold. If frig shows 50 degrees or higher, you have a defrost control parts failure. Can be defrost heater, defrost thermostat, defrost timer, or the air circulating fan in back of freez compartment. If you are not very capable of removing sections of the inner freezer and do not have good diagnostic skills, best to leave it to a professional. Good luck, Macgivor

also check defrost timer,defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

Freezer works fine fridge part not working at all, magic chief

I would look at air flow as the cause. First, look at the inside back wall of your freezer. If you see a buildup of frost, you have a problem in your defrost system (timer, heater or thermostat). Second, listen for proper operation of your evaporator (freezer) fan. I have seen motors turning too slow or blades coming off the motor shaft.
You may also make sure the fresh food door closes properly, and the light goes out inside the fresh food compartment.

MAGIC CHEF CTF1920ARA - Freezer works, Refrig. portion does not.

Sounds like a defrost problem. Check to see if there is any frost buildup in the back wall of the freezer. If so, it is not defrosting as it should.
  • possible causes:
  1. bad defrost timer
  2. bad defrost heater (in freezer)
  3. bad thermo switch in freezer
If you don’t know what these are then unplug the machine and let the ice melt in the freezer overnight with the door open. Then try it the next day, if is cooling fine then you need to have a service person replace one of the above items.
