Question

Stumped! Heil furnace.


I've got a 15 yr old heil furnace with issues. The fan kicks on, the glow igniter turns on, the pilot lights, but the main burner will not kick on. The gas valve is a year old and the igniter kit is 5 minutes old. I replaced it because it made since that that might be the problem.(but its not) any help would be appreciated.

check to see if you have 24 volts at gas valve..if you do bad valve,,,if you don't check for open limit, open roll out switches,,or other saftey switches....may be some saftey switches on blower housing.....

Are you talking about where the wire harness gets plugged into the gas valve coming from the igniter?

I just checked a switch where the rubber hose hooks up and I am getting infinite ohms. Should I be or is that a bad safety switch?

if pilot lights as you have indicated then iot could be that the flame sensor is not positioned properly to sense the pilot flame ..it should be positioned to have tip in flame and be close to ground/metal area of the sensor bracket..also could be touching metal somewhere thereby shorting the sensor out to ground OR cracked insulator allowing short

OR bad board?

I am starting to think bad board. Would it go through every step except the last step with a bad board?

A harness from the igniter to the gas valve sounds like a Smart Valve with all its attendent pin connection problems.

It is the new style valve. I replaced the old one last year. Could it be the board? Considering how far through the process it's going.

Yes it could be the valve or the board! It's just that possible valve system gives us all so many problems.
If you give us the make & number of your gas valve or better yet
post a picture of it, the answers will be more helpful.

I feel like I have tested everything. But not sure I am testing the gas valve correctly.

ignition control is part of gas valve.Double check ignitor/sensor is mounted in pilot assy properly.I had one that was not setting properly due to c clip not installed right, and flame sensor was touching pilot hood.Pilot would lite but no main valve.Repositioned correctly and furnace took off.
