Lennox G43UF-36B-070-07 : Ignitor Glowing, No Flame

[Jeremiah]

This has three tubes, and the ignitor is on the right-most one, with the flame sensor on the far left. When I turn on the power, the ignitor glows, but we never get a flame. It cycles through a couple times, and then shuts off.

Where should I go from here?

I have a picture of the tubes/ignitor, if that would help.

  If the ignitor is glowing then either there is no gas or the gas valve is not getting power to it. do you here a click when the ignitor is glowing try to open the gas valve?

If you do valve is getting power check valve. If not valve is not getting power. Possible bad board.

Turns out the problem was, in fact, that there was no gas getting to the unit. The landlord of this condo had not paid the gas bill, and the gas had been locked down.

Teaches me to look for the easiest solution to the problem first.

Thanks for your help.
