I went out to the motorhome to fetch some screws, and noticed that a fan
was running. It was the furnace blower. So, I figured last time I was in
the coach, I must have bumped the thermostat switch and turned it on. Nope,
it was off. I pulled the thermostat cover and confirmed that "off" meant
"off".
Left with no other way to make the furnace blower stop, I pulled the fuse
on that circuit. Whatever ghost was making it run then decided to take a
break.
My furnace, which is maybe a 15-year-old Suburban, has stopped working a
year or so ago (maybe more), and I've had it on the list to pull it for a
while to figure it out. My furnace is mounted in a non-standard spot, under
the cook top in the corner of my L-shaped galley counter. It's not easy to
access it at all, so I've put it off. For the little bit of heat that I
only occasionally need, the heat strip in the roof air has been adequate to
take off the chill.
The previous symptoms were the usual: Blower would start but the gas valve
would never open. The electronic starter was working, though I has probably
tried to start that furnace about a million times in the who-knows-how-long
period it was running. Could have been the sail switch, but I don't know.
But now I guess I'll have to pull it and figure out what's going wrong with
it.
Anybody ever heard of the furnace running with the thermostat turned off?
Other than the thermostat wire being chewed by a $%&%(*&#! mouse, that is.
