I recently had the old 'furnace fan runs for 30 seconds then shuts off' syndrome.
Turned out to be a loose wire on the sail switch.
Just used it a few minutes ago (we are at the Colorado Springs HOC Rally) and it is now working great.
Yesterday before we left I ran over to Walmart and bought a Pelonis Oil Filled Radiator space heater . . . on sale for $34!

I've been wanting to get one for a while now.

It warms up the Prowler's living room and kitchen pretty good.
Got down to 40 degrees here last night and it kept the chill down and the furnace never ran once until I bumped it up this morning just to make sure it was still going to work after the drive here yesterday.
