WARNING: Before working on any appliances that have
electrical components, be sure to disconnect it from its power source
completely. Not doing so could result in injury or harm to yourself.
Make sure your refrigerator’s temperature is within proper
range between 37-41°F and your freezer is set between 0-5°F.
To check if your thermostat needs to be replaced, rotate it
from the lowest to the highest setting and wait to hear a click. If you do hear
it click, then it’s probably not broken. If you do not hear it click, use a multimeter
to check its continuity. If it does not have continuity at any setting you may
need to replace it.
If your thermistor is damaged or defective the evaporator
fans may run more often than needed, causing your fridge to become more cool
than normal. Use a multimeter to test it for continuity. If it does not have
continuity, then it may need to be replaced.
If the control board is damaged or defective, it might send
continuous electricity to your fan motor or compressor. This may cause your
unit to cool off more than needed. If none of those points listed are at fault,
consider replacing the control board.
