Suburban Furnace (2nd post)

[magnuson mike]

Here is my original post.
Does anyone have any information on the workings of the suburban furnace.
Mine lights ok and appears to work great but when it reaches temp and the
burner shuts off if I watch it every once in a while a burst of flame will
run across the burner itself. Is this normal or is there a switch or valve
leaking somewhere?

For those of you that responded to the fridge, Thanks!
