If your Black and Decker refrigerator is freezing everything, then something has gone wrong. This article helps you to troubleshoot the refrigerator in order to find and correct the error.
Black and Decker Refrigerator Freezing Everything – What to Do
Do the following if you find that your Black and Decker refrigerator or mini-fridge keeps freezing everything you put in it:
1. Inspect the Damper Control Assembly
Open the refrigerator; you will find something that looks like a blinder. Study it for a short while to see whether it closes at the point when the refrigerator’s temperature falls to a certain point.
If it remains open even when the refrigerator’s temperature is below the setting, then the damper is stuck. Replace it.
The damper control of your Black And Decker refrigerator opens or closes to allow the flow of the right quantity of cool air meant to keep the refrigerator’s content cool.
If the damper control assembly is malfunctioning, chill air continues to enter the refrigerator without check. This can lead to improper temperature. It will eventually cause foods, vegetables, fruits, and soft drinks to freeze in the refrigerator.
2. Confirm the Soundness of the Thermistor
Test the resistance in the thermistor using a multimeter. This is to ascertain the soundness of the thermistor. A sound thermistor’s resistance changes in direct proportion to the temperature of the refrigerator. Also, test the soundness of the thermistor by checking for continuity.
The failure of the thermistor’s resistance to change as the temperature of the refrigerator changes shows that it is defective. In the same vein, if the thermistor lacks continuity when tested with a multimeter, then it is defective. And if it is defective, then replace it.
The thermistor is sensitive to the temperature of the air in the refrigerator. The thermistor reads the temperature and sends it to the control board of the refrigerator. The control board then regulates the refrigerant system, but it relies on this temperature reading.
Damaged, the thermistor gives wrong temperature readings. Because of this, the control board goes ahead with the wrong temperature readings. Hence, even when the board should stop the evaporator fan and compressor, it keeps them working continually. This is bound to cause over-freezing.
If the thermistor is not working well or is defective, it will fail to send the right amount of voltage to the cooling system. As a result of this, the temperature in your refrigerator will be either too low or too high.
A malfunctioning thermistor can result in the fan motors and the compressor operating continuously. It is this occurrence that makes the refrigerator compartment become too cold.
Use a multimeter to measure the thermistor’s resistance. If the resistance varies with the variation in the refrigerator’s varying temperature, then it is working well.
3. Check the Thermostat
Check if there is an electrical fault with the thermostat using a multimeter. Put the probes in the right wires and rotate the knob to turn it off.
If the multimeter does not read “O.L.” when the knob has been properly turned off, then that the thermostat is sticking. Replace it.
But if it reads “O.L.” when the knob is off, then the thermostat is working well. As such, the problem must have come from the temperature tube of the thermostatic control.
The thermostat control is responsible for turning your refrigerator on and off. It also monitors the temperature of the air in the freezer and refrigerator. The thermostat directs voltage to the compressor, condenser, and evaporator fan motors.
If the thermostat is faulty, the compressor will operate more than is needed.. This, in turn, causes the refrigerator to freeze food.
You can also check the functionality of the thermostat by turning the knob and listening for an audible click. If you hear it, it means the thermostat is good. But if not, it is likely to be faulty. So replace it.
4. Defective Temperature Control Board
A defective temperature control board is not a common occurrence. So it should not be the first port of call. Check other parts before going to check it.
But if you find that the one in your refrigerator is bad, replace it. You may not be able to test it yourself. Therefore, find a repair agent to replace it.
Sometimes, simply cleaning the condenser coils fixes the freezing issue. When the coils are dirty, they cause the compressor to work hard to remove heat from the refrigerator.
In doing this, there is no ‘off’ time for the unit. What this means is that it will keep working and over time, the unit will freeze.
So clean the coils. Shift the refrigerator away from the wall and wipe them down. Use a condenser brush if you have one. Otherwise, clean with the brush head extension of a vacuum cleaner.
Contact Black and Decker to report any issue you cannot fix on your own. Otherwise, chat with our refrigerator technicians who are available to help you find and fix the fault.
