Electric Furnace

A well designed heat pump system has an outside temp sensor. This sensor will prevent operation if the temps outside are below freezing (The actuall cut off may be as high as 40 degrees) and thus prevent heat pump operation at low outside temps.

I have discovered the problem. It was an ID Ten T error. Heat sources work as they are supposed to.

I have posted in "Around the Campfire" about the bullet hole. We were returning home from Branson, Missouri on I-44, about 15 miles from the Oklahoma/Missouri border. A round from a .30 caliber rifle, probably a 30.06, smashed the window above and behind my head. Only after stopping and cleaning up the glass did I discover the bullet hole and the spent slug. Obviously a spent round, since it didn't have enough velocity to penetrate the curtain. Or maybe some hunter thought he had just shot a 40,000 pound elk being chased by a 4,000 deer...

I have both in my motorhome. The propane furnace works separately.

Tell us more about the bullet! Was that in "Indian Country?" Hope it wasn't "Up Here" on your last trip. (Although the natives are getting a bit restless lately.) You might have to spend more time up here to keep out of trouble. :) Sorry, not a clue about your furnace issue! :(

I can choose either gas or electric as a source for heat, in two zones. It wasn't that cold when the electric heat quit working in zone one. I still had electric heat in zone two. I haven't really checked it all out, but will be putting it in the shop for various fixes in the near future, including the window that was shattered by the bullet.

GM

you don't give a lot of information. I'm going to assume that you have a combination Air conditioner and heat pump along with a propane furnace. If that is correct, then the heat pump will only work down to about 40-45 degrees outside temperature. How cold out was it? The propane furnace is most likely controlled by the same thermostat on the wall but is otherwise an independent system. Did the front heat pump try to come on at all?

If you are referring to a heat pump, where does the propane come in?

Jim

My bad. Electric heat pump.

GM

Yes, confusing, could be a heat pump, could be an electric insert in the furnace. It isn't clear what GM is referring to.
