Suburban Furnace Problem

I have a Suburban furnace in my 87 Southwind. It will not produce heat. The sail switch is working, as is the high temp sensor and the propane tank is full. It was working fine, but then just quit producing heat. Any suggestions as what to look at next?

Does it have a pilot light or an ignitor? Check that the ignitor is lighting. If it then shuts off the gas, it probably is the heat sensor. If it tries to light 3 times and fails, the furnace goes into lockout. Reset lockout by turning power to furnace off for a minute or two.

See page 22 for sequence of operation. Take the outside cover off the furnace and stand near as someone inside turns on furnace. See where in the sequence your furnace fails. If it doesn't do anything but let the fan run, it could be a bad circuit board.

Thank you for the link, it is useful. The furnace has an electronic ignition setup and sparks very well. From what I have read and tested, my guess is that it is going to be the gas valve not opening. So I guess I will have to pull the furnace out and take it apart to test the module and the electric gas valve.
