i have a coleman evcon m# DGRT070AUA s#9308.... the burner lites, but will not bring trailer up to temp, before furnace shuts down entirely. then i have to relite pilot/igniter, burner comes on for short period, fan kicks on for a minute then everything shuts down again! can anyone help? thanks, tom

Hi,

Will have to locate interruption in low voltage power to gas valve.

Could be t-stat, a limit or a overheating problem inside furnace chamber.

First trace the circuit to find where the power to gas valve was interrupted.


Thanks,
Robert
