GEAUX LSU TIGERS!!!
We have a 2010 Bighorn 3580RL. We didn't use the trailer for a few months and then camped at a place where it was cold. When we got setup, I turned the furnace on to heat it up since it was about 30 degrees when we arrived. You could hear the starter click and try to light a fire, but the fan never turned on. When I just turned the fan on, it works. I just filled up both propane tanks so that shouldn't have been an issue. After several attempts, I checked the 12 volt fuses and the furnace one was blown. It was a 20 amp. I replaced the fuse and tried again, and it instantly blew the fuse as it tried to turn on. I thought it was a grounded wire somewhere or bad circuit board. My dad and I took the cover off of the outside exhaust and we looked and didn't see anything at first. Then, with a flashlight, my dad saw some dirt dobber nests inside the top tube that goes to the squirrel case blower. The nests kept the blower from moving and blew the fuses. Once we knocked the nests loose and removed most of it, we replaced the fuse and it started right up. It was a little noisy at first, but after a few times of it kicking on, it sounded right. I think it still had a little of the nest in there. I didn't have a screen on the exhaust pipes. If so, this would have been prevented. I will now install a screen. I think this $5 part should be installed at the factory on new trailers. Or at least offered as an option or highly recommended by all dealers when they sell them. They'd make a few extra bucks and the new owners wouldn't have this issue. Hope this info helps someone with the same problem.
