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.
REED SWITCH
A reed switch is used to monitor door state. When the
door is closed magnetic force pulls the reed to its contact
and closes the circuit which turns the light and display off.
When the door is open the reed pulls away from the
contact and opens the circuit. If the door is left open for
longer than 5 minutes, the switch will trigger an error code
and set an audible warning.
