Ignitor - GE DPGT750EC/GC Technical Service Manual

• The control operates the gas valves by
supplying voltage based on varying duty
cycles.
• It is difficult to determine specific voltages at
the valve due to software algorithms based on
clothes load and temperature settings. The
most accurate diagnostic check is to measure
resistance of the solenoid coils.
To remove the gas valve:
1. Shut off the gas and electricity to the dryer.
2. Remove the
Top Cover
3. Disconnect all wiring to the gas valve and

ignitor.

4. Remove the 2 Phillips head screws that hold
