I Suburban SF20 furnace is not working. I have a 2009 F/R Surveyor 235RKS. If I click it on, the blower starts for 20 seconds and shuts off. I am not hearing any clicking from the ingiter or smelling any propane. Any ideas? Any help would be appreciated.
Sounds like a bad sail switch. The sail switch senses that the fan is running, if it isn't then it shuts down before opening the propane valve. Find the sail switch, bypass it with a jumper and see if it will run though the entire startup process. If it does then the sail switch is bad.
The caveat with this is that you have shore power plugged in or you are sure you have good batteries. Not enough amperage will cause the fan to turn to slowly to close the sail switch.

If you bought your rig new you should have received a manual for the furnace which shows a parts breakdown. If not you can ask for one from a Suburban repair facility. You can also refer to this Furnace Information document put out by Suburban.
If you have an access door on the outside of your RV to the furnace you may not even need to remove it to work on it. This is the way it was on our older Fleetwood motorhome we used to own.
