Food in the refrigerator department is freezing. I checked the refrigerator temperature setting and it is 46 deg f. I checked the freezer temperature setting and it is 5 deg f.
I put a NIST traceble...
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.
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
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.
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.
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.
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.
