Propane heater troubleshooting?

[sfedeli3]

Steve,

On my PT, I found that my LP heater in the bedroom did not work.
You should test for 12V at the thermostat first (it should always be
on if your 12V master switch is on). If you have that, then make sure
that the thermostat is good. Mine was burned out from a design flaw in
the furnace. Turns out that the 12V goes to the propane valve AFTER
the blower fan via a microswitch. In the furnace, the 12V power wire
to the fan travels very close to the hot metal surface of the exhaust
vent. Mine had melted to the vent and was shorted. Once fixed, it
worked fine. IF your thermostat is burned out, that wire to the fan is
the FIRST thing I would check in the furnace. Why Suburban ran the
power wire this way, I'll never know.. It appears to be a source for
problems. Check for 12V at the thermostat first, then turn up the heat
and see of the thermostat is allowing 12V to go to the furnace.
