My Honeywell magicstat thermostat is not heating the house at the temp it's supposed to. Why?

The furnace comes on sometimes, so I know it's working. I put new batteries in the programmable thermostat just now, and it's still not work. It's subzero outside, and the thermostat is programmed to heat the house to 72, but it's only 64 in here! The thing seems to be stuck on 64 degrees because that's where the temp in the house stays! Anyone have any ideas how to fix this?My Honeywell magicstat thermostat is not heating the house at the temp it's supposed to. Why?It holds a constant 64 degrees? It could be a defective thermostat, but I would suspect an intermittent problem with the furnace. What kind of furnace do you have? Make and aprox. age. Forced air or boiler? Electric or gas?My Honeywell magicstat thermostat is not heating the house at the temp it's supposed to. Why?could be the tstat,but more likely is the furnace...has it heated the house to 72deg in sub-zero temps in the past?.its possible that its undersized,though not likely.....you can test it by removing the tstat from the subbase and jumping out [ connecting ] the wires that presently connect to the %26quot;r%26quot; [or %26quot;rh%26quot; ] and %26quot;w%26quot; terminals,,assuming its a regular gas or oil furnace...that bypasses the tstat,,see if house temp goes up,,might take a couple hours to tell for sure...if temp goes up,,it was the tstat...if temp doesnt go up,,its the furnace...sometimes minor or intermittent problems with the heat arent noticable until it has to run continuously for a while,,then not only are they noticable,but they get worse...if its a boiler,,it could be that the radiaters capacity to disipate heat isnt quite enough.....anyway,,jump out the 2 wires and see if furnace catches up,,,fyi,,dont go to sleep with wires jumped,,,only do it while you can monitor operation......danMy Honeywell magicstat thermostat is not heating the house at the temp it's supposed to. Why?Not enough return air possibly. Change out your furnace filter and see if that helps. Check to make sure that all of your vents are open in your house. If this still does not help, I say replace the piece of junk. get a White Rodgers T-stat. You might also check to make sure that all of your dampers are open and that your duct work is hooked up everywhere. Good luck.
