Hi I have a Coleman Evcon furnace model dgat056bdf furnace that quit recently, first I bought a gas valve, but the furnace started working again before I got back from purchasing it, so I let it keep working, it worked for a month before the ignitor failed, so I had a tech. replace both items, then it worked half the night, then quit giving gas to the ignitor after it lit up sufficiently, so we figured we got a bad gas valve, bought another, installed it, tested the voltage going to the gas valve, and it was 24, tested the gas pressure at the inlet, it was good, the outlet wasn't, BAFFLING, huh?/ then we applied 24 volts to the gas valve separately and it opened, re-installed it to the same problem, HELP..
