do you have the manual?? most manuals will have a troubleshooting section that will recommend corrective action.

if you do not have a manual, contact Coleman, most manufacturers are more than happy to provide manuals for free.

You can probably download one from their website.

If the ignitor energizes then most likely no gas flow. So could be no output from board, low gas pressure, failed gas valve as a few examples. Check to see if there is 24V at the gas valve after the ignitor goes through it's warm up cycle.

I agree with Subcooled...you gettin 24v to the gas valve?

What bothers me is....when does the main blower come on (or were you talkin' about the vent motor?)

If the main blower starts before the ignitor works, your faulting out somewhere else sooner, that is, before the gas valve.

Some furnaces will energize the ignitor but not the valve if there is a pressure switch problem if 90% furnace check drains and venting and just venting on 80% furnaces
