GE DPGT750GC Gas Dryer Problem

I made the 'Guest' post last night, and have since found more info.

You can enter service mode by:
1. Power on (press 'POWER')
2. Press (and release) 'HOME' (will beep twice I think but doesn't matter)
3. Press (and release) 'HELP' (again with the beeps)
4. Press (and hold) 'MY CYCLES' and 'BACK' together (hold for ~3 seconds)

It will then give you more detailed info as to the specific problem, plus suggestions for what to check. When you exit service mode (via on-screen 'EXIT' touchbutton), it will tell you that you have to unplug the dryer to reset it. After replugging, it will run a setup/diagnostic which tests the door switch, panel buttons, touchscreen, beeper, motors, heating, etc.

Good luck!
