High Limit Thermostat
The high limit thermostat is located on the top
right area of the heater housing. The high limit
thermostat monitors incoming air temperature.
If the thermostat reaches a temperature beyond its
maximum temperature rating, it will trip and disable
power to the motor, elements, and the drum light.
The high limit thermostat opens at 315°F (157°C)
and will automatically reset at 250°F (121°C).
To remove the inlet high limit thermostat:
Remove the top, control, and front panels. (See
Top Panel, Control Panel and Front Panel .)
Remove the drum. (See Drum .)
Disconnect the 2 orange wires from the high
limit thermostat.
Remove the single Phillips-head screw, then slide

Outlet Control Thermistor
The outlet control thermistor is located on the lower
rear area of the blower housing. It is below the
outlet control backup thermostat. The outlet control
thermistor measures outgoing air temperature
and responds to temperature changes. The outlet
control thermistor provides temperature change
information to the power board. The power board
makes heating decisions based on this information.
The outlet control thermistor has the same
resistance values as the inlet control thermistor. (See
Inlet Control Thermistor .)
Operation of the outlet control thermistor can be
checked by using service test mode t07. (See
Service
Test Mode .)
Specifi c failures associated with the outlet control
thermistor can initiate error codes E03 and E05. (See
Service Test Mode .)
To remove the outlet control thermistor:
Remove the top, control, and front panels. (See
Top Panel, Control Panel and Front Panel .)
Remove the drum. (See Drum .)
Disconnect the 2 blue wires from the outlet
control thermistor.
Remove the 2 Phillips-head screws that attach
the outlet control thermistor to the blower
housing.
