REFRIGERATION SYSTEM DIAGNOSIS GUIDE

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. In an ice water 
bath (32°F) resistance should measure 16.1 kilohms.

5K OHMS @ 77°
16.1K OHMS - 32°F ambient

THERMISTOR FAILURE

Limp Mode Data Table

Zone Thermistor

If the zone thermistor fails, the unit will continue to 
operate in a timed limp mode which varies by model. The 
unit will otherwise operate normally. The error will be 
displayed in the error log.

Evaporator Thermistor

If the evaporator thermistor fails, the unit will rely on a 
preset defrost time during defrost cycles. The unit will 
otherwise operate normally. Evaporator thermistor errors 
will be displayed in the error log.

Always assure that all thermistor connections are clean 
and dry. Whenever opening a thermistor connection be 
sure to apply a fresh dab of die electric grease.
