My wife and I bought a 2008 pop up last year and used the furnace-- everything worked up until we took it out this year and couldn't get heat going... I replaced every fuse in the box, along with wiring a new lp detector in but still nothing. The battery has a good charge, the fuses have been swapped out, new lp sensor and even tried connecting to shore to be sure. The stove lights, so there is definitely propane flowing. However the pilot on the thermostat as well as the furnace blower and lp detection are failing to work. Any ideas?
