I'm having a problem with my furnace. It goes into watchguard - burners failed to ignite. the fan comes on, the starter/ignitor glows red, I hear a click (I assume gas coming on), then the right and sometimes middle burners flame on for a half second, click, and the burners go out. This repeats 4-5 times, then back into watchguard.
Anybody have any ideas on what I might be able to try to get this working?
