Unscrew the 4 screws holding the furnace plate on, there is a switch, make sure it is in the 'on' or 'reset' position.
Was the fan running but just not igniting?
Make sure you have propane in your tank. Turn on the stove until you can light it, this takes about 30-seconds for the propane to reach.
Also, there is a metal switch on the frame rail behind the battery, make sure it is pulled out to the 'on' position. This is the battery cutoff switch.
Go on your roof and make sure the seam between the front cap and the roof doesn't have a gap. WW and Ragen' are notorious for this and then you get rot :-(
Post a pic :-)
