I have a GE Gas Dryer, DPXR475GW, that starts and runs, but the burner stops after 10 - 12 minutes.
Restarting the dryer, the burner no longer turns on, drum spins normally.
If the dryer cools down for an hour or more, it will run with heat for 10 - 12 minutes.
Same operation with different heat settings.
First item I checked was for lint blocking the exhaust path, from the lint tray to the exterior vent, found some and cleaned it out. I went so far as to disassemble the cabinet and clean out all ducts in the machine.
While I was checking for lint, I removed electrical thermostat located on the blower housing, and noticed a slight rattle.( p/n 540B146P011)
How do I test the thermostat ?
