Magic Chef Refrigerator Freezing Up – What to Do

Here is what to do if your Magic Chef refrigerator is freezing up:

1. Check the Temperature Control Thermostat

To know if the thermostat is faulty, turn it from the lowest to the highest setting and listen for a click. If it clicks, then the thermostat is not faulty. But if it doesn’t click, then test its continuity with a multimeter. If there is no continuity at any setting, high or low, replace the thermostat.

The thermostat gets the compressor and fan motors running efficiently by sending voltage to them as they need it. If the thermostat is faulty, the fans and compressor could run more than the refrigerator needs. This can make the unit become too cold to the point of freezing.

2. Check the Damper

To find out if the damper is broken, take a look at it between the fridge and the freezer. If it is in the open position and doesn’t close or if it is slightly open, the damper is broken and should be replaced.

The damper handles the amount of cool air that goes into the refrigerator. If it is stuck open, then the amount of cold air cannot be controlled. So the refrigerator gets too cold.

3. Check the Thermistor

To know if the thermistor is defective or not, use a multimeter to test it. You should find its resistance changing with the temperature of the refrigerator. If the resistance doesn’t change and there is no continuity, change the thermistor.

The thermistor reads the temperature of the surrounding air and sends the readings to the control board of the refrigerator. Then, with the readings, the control board powers the evaporator fan and compressor. If the thermistor can’t do this, the fan and compressor are likely to operate beyond what the refrigerator needs. Consequently, the refrigerator gets too cold and even freezes food.

The main control board or the temperature control board could also be defective. But don’t check them until you are sure none of the parts mentioned above is faulty. It is easy to misdiagnose them as the problem and hence, throw out a perfectly good board. However, check either of them if all else works well.

Magic Chef Mini Fridge Freezing Up – Solution

Ensure you set the temperature at the right setting. The temperature control is numbered 1 to 5, 5 being the coldest, and 3 is the recommended setting. So setting the fridge at 4 or 5 will cause the fridge to freeze.

Be sure the seal of the door is still reliably keeping air out of the fridge and keeping the cold air in the fridge. If the seal is compromised, it will affect the freezing ability of the fridge. Humid air penetrating the fridge will cause condensation and over time, will build up ice by refreezing the moisture from the air.

Furthermore, avoid storing food or other items too close to the air vents. The food will freeze too quickly, being too close to the cold air. It will also affect the circulation of air in the fridge and this can lead to the fridge freezing.

Additionally, don’t open the door too often. It will compromise the air in the fridge. Warm air carries moisture easily so if it enters the fridge, the moisture will condense and freeze. If the warm air keeps entering, eventually, ice will build up in the fridge.

All the above is applicable to all Magic Chef fridges, including Magic Chef wine coolers and beverage coolers.
