I have a DLGX7188RM that stopped producing heat. I replaced the thermistor, which gave us about five loads of heat before kicking off again. I then replaced the thermistor again along with the blower thermostat, the high limit thermostat, and the burner tube thermostat. That got the dryer working again, but did not last through a single load. I have tested the igniter, the igniter sensor, and the gas valves with a multi meter, all seem to show the proper continuity / resistance. Short of the control panel, at a bit of a loss as to what else the issue could be. I have cleared out the discharge duct, it is now clear. Would appreciate any thoughts!
