YES,......running element directly bypasses the circuit board/thermistor/thermostat...all controls
Continuous cooling cycle until you unplug the element
And the 30*F temp indicates that it DID cool down (that 30*F is FOOD Compartment temp right??)
SO you know cooling unit works
Now is circuit bd bad or is thermistor the issue
That is why I suggested with everything back to normal....unpklug the thermistor and run fridge test again...temp setting on 9 (max cool)
Then tomorrow check temps
Low temp.....thermistor is bad
Temps not cold.....bad circuit bd
