Thermistors
Thermistors are used for various temperature readings.
Thermistors provide reliable temperature readings using a
resistance which varies based on surrounding
temperatures. If a faulty thermistor is suspected it may
be tested using an accurate ohmmeter.
This unit has two thermistors. One type one thermistor
and one type two thermistor.
The type one thermistor is located along the right hand
side wall of the ice bin and is used to regulate the level of
ice in the storage bin.
The type two thermistor is located on the liquid line
between the condenser and the filter dryer. It is used to
control the length of the freeze cycle during ice
production.
A type one thermistor should OHM out at 16.1k OHMS in
an ice bath or 5k OHMS at 77°F +/-5%.
A type two thermistor should OHM out at 10k OHMS at
77°F +/-5%.
Thermistor connections must be kept clean. A thermistor
connection that has become corroded can cause
resistance values from the thermistor to change as they
pass through a dirty connection to the board.
It is for that reason that we apply die electric grease to all
of our thermistor connections. Die electric grease will help
to keep thermistor connections clean and dry.
If you change a thermistor in the unit please re-apply die
electric grease to the connection. If you encounter a dirty
thermistor connection, you should replace the thermistor
and the thermistor harness.
