[VAC] Re: furnace

[Weimers]

I don't know what's in your '86, but I've had two Suburban furnaces. You have to take them out of the trailer and take the guts out of the furnace (Not too hard). There is a sail switch that detects that the fan is blowing air through the combustion chamber. If the switch gets stiff or the air flow gets blocked, the switch will not activate and you will get not flame in the furnace.   Before you take the furnace out, try blowing a shop vac into the vents on the outside of the trailer (with the furnace turned off). Something might be in there blocking the air flow. I had a wasp nest in mine once.   MARC WEIMER Punxsutawney, PA  -  Home of the Groundhog #15767 1963 Globe Trotter 1971 Globe Trotter http://users.penn.com/~mweimer/weimer.html ----- Original Message ----- From: Dennis Ober To: Multiple recipients of VACList Sent: Wednesday, April 18, 2001 8:42 PM Subject: [VAC] furnace      I have a 86 a/s ....the furnace fan comes on but not the burner flame ... do I have to take out the whole furnace to get to the relay switch or circuit board ...does any one else have or had this burner promblem ...what should I BE LOOKING FOR ??thanks ...keep up the digest  ...I read it every day ... only 10 more years till mine is a vintage ......
