Thermistor

Evaporator Thermistor

If the evaporator thermistor fails, the unit will rely on a 
preset defrost timer during defrost cycles. The unit will 
otherwise operate normally. Refer to defrost section.

Thermistor Resistance Data

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.

Both thermistors in the unit are identical. If a thermistor 
is suspected of being defective, the resistance can be 
verified. Place the thermistor in an ice water bath, the 
resistance should read 16.1k Ohms +/-5% on your meter.

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 dielectric grease to all of 
our thermistor connections. Dielectric grease will help to 
keep thermistor connections clean and dry. 

If you change a thermistor in the unit please re-apply 
dielectric grease to the connection. If you encounter 
a dirty thermistor connection, you should replace the 
thermistor and the thermistor harness.

Thermistor error information can be found in the Control 
Operations - Service section.

This unit has 

two

 thermistors.

Thermistor one (Zone):

Located along the right hand side wall. It is used to 
maintain the operating temperature within that zone.

Thermistor two (Evaporator):

Located on the evaporator. It is used for defrost.

THERMISTOR FAILURE

Zone Thermistor

If the zone thermistor in the unit fails, the unit will 
continue to cool in a backup mode (Self Preservation 
Mode) to preserve the integrity of the contents. The unit 
will otherwise operate normally.

This unit has one thermistor located along the right hand 
sidewall of the ice bin. It is used to maintain the ice level in 
the bin.
