We have a newer 3 bedroom moble home. We have a propane furnace. At night the furnace runs non stop. I have talked to the landlord and he said that the furnace is fine and so is the thermostat. Right now it is set on 70 and it is 67 in here (according to a diffrent themometor) The furnace has not stopped running since I have been home (2.5 hrs). I have storm windows on and DOUBLE plastic. What the heck is going on here? We are always cold and are going through Propane like crazy. When the blower kicks off the burner automatically kicks right back on.

I am not talking about the thermostat setting, imtalking about the temperature stting of the air that comes out of the air vents. I saw a place on my furance where i could set the temperature but im not sure what to set it to?

I am renting a basement apartment – the tenant upstairs tends to leave the furnace off all weekend when they go away leaving me to freeze with just a space heater to keep it warm. The furnace is accessible from my apartment – is there anyway I can turn it on from downstairs?
Talking to the people upstairs doesn’t work – I think they do it on purpose as we don’t get along. The landlords are useless as well.

Have moved into a house where previous owner replaced simple mechanical type thermostat (with mercury bulb) with an electronic unit. Mechanical type obviously just closes a contact to complete the gas valve circuit and so get 24V across gas valve coil.
Obviously 2 wire electronic unit cannot do this because the unit needs to draw power for the electronics.
The new thermostat is giving unreliable operation, am thinking of replacing it with the old unit which I found and appears to be functional (checked with multimeter).
