Hi-Limit Thermostat; Gas Valve - GE DPGT750EC/GC Technical Service Manual

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 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).
To remove the hi-limit thermostat:
1. Remove 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.

Gas Valve

The gas valve assembly is located in the bottom,
right, front corner of the dryer cabinet.
• 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.
