Hello,
When the refrigerator side is getting too cold this is because the control of the compressor has gone bad in some way...
There a few different things that could cause the unit to lose control over the temperature of the fridge side.
If
your refrigerator has a damper door that opens and closes to allow cold
air to move to the fridge side the damper linkage or the damper motor
may have broken or gone bad.
The coils in your fridge may have
frozen over and now the air does not move at all so then the ice builds
up and can freeze parts of the fridge side.
The thermostat has
gone bad and so now the compressor runs continually. This will not be
noticed readily on the freezer side but will show up quickly on the
fridge side.
Many newer model refrigerators use an electronic
sensor or thermistor to read the temperature and supply the info for
the circuit board and often a digital readout.
So, here is how I would go about troubleshooting this problem.
Check
the coils for ice, defrost the coils with a heat gun or hairdryer, then
check for the reason why they iced over. Defrost control or defrost
timer bad? Evaporator fan bad?
Check the damper door to see if it is stuck in the open position. If it is then check the motor and the linkage.
Check
to see if the refrigeration unit will shut down if the thermostat or
digital setting is turned up to a higher temperature. If it continues
to run then find the cause and fix it. It may be a bad thermostat,
sensor, or control board.
Sometimes
with a change is weather to a cooler climate this will be enough to
also affect the inside temperatures. Make sure that a bit of adjustment
in the thermostat or setting of the temperature will not solve your
problem very simply.
I hope the above helps.
Good luck.
This product comes equipped with an Adaptive Defrost Control (ADC). To activate manual defrost, press and hold the Freezer temperature UP (WARMER) key while pressing the Fresh Food temperature DOWN (COLDER) key 5 times within 6 seconds. A "d" in the freezer temperature window and "F" in the refrigerator temperature window will display when the heater is activated. To deactivate manual defrost, press and hold Freezer temperature UP (WARMER) key while pressing the Fresh Food temperature DOWN (COLDER) key 5 times within 6 seconds. "d" and "F" will be displayed until the defrost cycle is complete. (approx. 8 minutes)
