How many ohms should a refrigerator thermistor read?
With the sensor warmed up to room temperature the sensor should read approximately 6.2K Ohms at 68°F. With the thermistor submerged is a glass full of ice water, the sensor should be very close to 32°F which should read approximately 16.3K Ohms.
Does my refrigerator have a thermistor?
