My lennox gas furnace, with electric ignition will not light. The flue blower won't shut off for hours. What's wrong.

Welcome to Just Answer,

You could have a (partially?) blocked vent or a faulty draft pressure switch. If the igniter initializes then you could have a faulty gas valve or control board
Customer: replied 5 years ago.

the igniter doesn't come on, and this thing worked perfect a week ago. Oh I just tried the A/C, that doesn't work either, and the flue blower is still running. I think the circuit board might be fried, thanks to an electrical storm we had a couple of days ago.

Should have diagnosed further before I ask. thanks for the response.
