Inlet Safety Thermostat
On electric models, the inlet safety thermostat is
located near the back of the heater housing, on the
left side. On gas models, the inlet safety thermostat
is located on the top right side of the inlet duct,
below the high limit thermostat. The thermostat
monitors incoming air temperature.
If the thermostat reaches a temperature beyond its
maximum temperature rating, it will trip and disable
power to the heating elements (electric model) or
burner assembly (gas model).
The inlet safety thermostat opens at 260°F (127°C)
and will automatically reset at 230°F (110°C).
To access the inlet safety thermostat, it is necessary
to remove the drum (electric model). On gas models,
remove the rear bulkhead for front service, or the
back panel for rear service.
The thermostat is attached to the heater housing or
inlet duct with a Phillips head screw and a tab. Two
wires are connected to the thermostat.
