Motor home furnace
I have found a little info on my furnace on a 1998 fleetwood discovery, which is not working. I couldn't find an owners manual, but did find a booklet for installation instructions. On this booklet it says Excalibur 8500-lll Series hydroflame furnace. I had no luck finding an owners manual on line.I found one other piece of literatue which showed the order of events when trying to lite the furnace. With the propane on and the electric on, turning the thermostat to heat and setting the temp set point, the blower should start running, but it does not.If any one has a thought to what the problem could be, please let me know, thanks. (I am able to light the stove burners so I at least know I'm not out of propane}

The first thing I would check is a bad fuse. The blower draws a lot of current.

When my furnace started intermittently working, then not come on (fan was blowing though), I called a mobile RV tech, and he let me watch, and he explained how it all works. He found that the connector on the circuit board was not making contact. He showed me how to clean it. It worked fine, but several days later...not working.
I pulled it out (2 min job) and cleaned the contacts at the connector, then applied some die-electric grease to them. It worked. Still working.

Try this one.

It is a hydroflame series IV
May be close enough.

The whole system depends on 12 volts. First check to see if you have power to the furnace. If so then disconnect the thermostat wires and use a jumper wire to connect the two terminals. The blower should run. If it does not, check the board connections, but you may need a new motor.
