my propane furnace quit on me fri night. and I desperately need one before going back to wisconsin next week, so I need to start shopping for one now. any body with one for sale or can direct me in the best direction to get one let me know. I need one for the new bus any way so I can use it in this one till then. I'm open for all kind of options that are not too expencive. might as well give me all the options. |

What isn't it doing, Ron? They're fairly simple in design..
50% of the time, insufficient voltage to the blower is the cause
for it not starting. Bug nests deep inside the intake or exhaust
tubes account for most other failures. Don't be too quick to
toss it out! |

I have it running on 110 not 12 volt. the fan blows but no heat. kind of sounds funny also. it's been making awierd noise for a while. |

(I'm assuming you have the standard RV Propane heater)
The standard 12v RV propane heaters that have the "110v" ability
run from it's own small converter. They are POS. Try running it
on a full 12v supply (engine running) and see if it'll fire up.
You may have to cycle it a few times by manually turning the
heater off, letting it sit a minute off, then turning it on again
with the thermostat set full scale.
Also, the burner has a small, replaceable orifice that runs about
$3 and takes some effort to replace, depending on the heater
and where it's been installed. But the first thing to check,
is the voltage supply feeding the blowers. If there isn't enough
wind blowing thru that fan, the flapper won't allow the gas to
be turned on, and/or shut the gas off, if it did run initially.
The fan will then (usually) continue to run, blowing cold air..
As little as a volt drop lower than what the fan requires, is
enough to cause it to turn off the gas supply. |

Incidentally, the blower motor set me back a whopping $45
when I had to replace mine. If the burner/heat exchanger
isn't rotted or burned thru, it is worth restoring. |

What kind of weird noise? A squeeky noise may mean the motor bearings, which means replace the motor. A rattle type noise may mean something is caught in the fan. A groan kind of noise may mean low voltage. a whooshing noise may mean gas train problems.
John is right about the 'flapper' switch, short it out and see if the furnace lights, if so, replace the switch. He is also right about bugs. Spiders LOVE the smell of LP and build webs in the gas train. Wasps find a dark, warm place great for nest building. And, if it is rotted or burned thru, dump it. Almost anything else, including an expensive PC board, is less than replacement. |
