Guys,

I haven't been on here much because everything in my coach has worked so well, thanks to all your help in the past. I hope I've repaid by helping others when I have something to contribute.

This Suburban furnace has given me troubles in the past. Turned out to be a venting issue that was easily solved and has run perfectly until . . .

Yesterday it was running when I woke up. Then it stopped, but it immediately started, then stopped, paused, did it again, then came back on, ran for five seconds and quit. I cycled the new last year, Suburban thermostat and the motor would start for one or two seconds, stop and immediately, I mean before the fan motor completely stops, it starts again for not even a second and quits.

I had to leave for work, so the warmer in my roof a/c unit did the job as I made coffee and breakfast. Only in the 40's here. Last night I turned up the thermostat and the furnace came on, got warm, and I thought, can I be that lucky? No is the answer. It did the on-off thing and died. I mean cycling the thermostat does nothing. The fuse is good. My volt meter is at the shop, so I can't test anything yet. Can't even find a paper clip to short out the two thermostat wires at the plug.

Just hoping someone has had a similar experience or advice other than buy a new furnace. Maybe a new Dno board? Anyone, Beuller?

As always, thank you.
