Gas Valve
The gas valve assembly is located in the bottom,
right, front corner of the dryer cabinet.
To remove the hi-limit thermostat:
1. Remove the
Top Cover
, the
Front Panel
, and
the
Drum
.
2. Disconnect the lead wires to the hi-limit
thermostat.
3. Remove the 2 screws that hold the hi-limit
thermostat to the housing. Remove the hi-limit
thermostat.
• The hi-limit thermostat monitors incoming air
temperature.
• If the hi-limit thermostat reaches a
temperature beyond its maximum
temperature rating, it will trip and disable the
heating function only.
• Heating functions will be restored when the hi-
limit thermostat cools and resets.
• The hi-limit thermostat on the electric models
has a trip temperature of 230°F (110°C) and a
reset temperature of 194°F (90°C).
• The hi-limit thermostat on the gas models has
a trip temperature of 194°F (90°C) and a reset
temperature of 158°F (70°C).

Hi-Limit Thermostat
The hi-limit thermostat is located on the left side
of the heater housing on electric models. It is
located on the right, upper side of the combustion
chamber on gas models.
• The gas valve consists of 3 valves operated
by 12 VDC solenoid coils.
• Two of the valves are either in an open or
closed state, depending on whether the coils
are energized by the control.
• The resistance value of these coils is
approximately 1900
Ω
.
• The third valve is a linear valve. The valve
opening varies depending on the amount of
voltage it receives from the electronic control.
The resistance of the coil on the linear valve is
approximately 65
Ω
.
