It also has the electric element on it with a on/off switch on the box for it (located under the back bunk). It was in the on position and probably has been for who know how long. Is there a breaker somewhere for this or is it just tied in with everything else? I'm guessing the element is probably bad. Haven't taken it off yet to look. We will use it at campgrounds with electric so the propane side can wait a bit. Just want to make sure there isn't another breaker somewhere that needs to be on for it to work. All the ones in the power converter are turned on though.
The heater and blower won't come on either. I noticed a missing fuse in the power converter box. Nothing in the box is labeled so I have no idea what it is for. I tried putting a 15 amp fuse in it, but it blows right away. Attached is a picture. It is second from the right. The first fuse is 25A and all the rest are 15A. Is this for the furnace and/or hot water heater(propane)? I've read the control board on the furnance can go out a lot. Would this be blowing the fuse? Are there any fuses in the furnace itself?
Just to give you a starting place, the furnace control board and blower motor are 12 volt and protected by a fuse.
The element for the water heater is 110 volt and may or may not be protected by a circuit breaker. The control board will be 12 volt and may be piggy backed with the furnace control board. It's anyone's guess until you tear into it and find out.
Try the photo again, it doesn't show up.
