Our furnace does not shut off at the set temperature. I have it set on "auto" and "heat". When it reaches the set temperature, it stops blowing warm air and just blows air (from the basement, so it's cool air).
Does this affect our gas bill? Right now, we turn it to "off" when it stops blowing warm air. It's a pain at night because it gets pretty cold. We rent, so as far as landlords go...we have a typical one... no response for days. Is there something simple we can do or will he have to call for service? We tried replacing the thermostat thinking this would fix our problem. Any suggestions?

No, it does not affect your gas bill, unless you set the temp higher because the cool air blowing makes it feel cooler, but it does affect your electric bill.
Contrary to what some have posted, the thermostat does not typically control the fan in the "heat" mode. The fan is controlled by the furnace.
In an electric furnace, the fan is controlled by a small time delay relay called a "Sequencer". If the sequencer sticks, it will keep the fan on too long.
In a gas furnace the fan is controlled by a Fan Thermostat on older units, or by an electronic control board relay on newer units. On GE and Trane units from the early eighties, there is a Camstat fan thermostat that uses a time delay to start the fan and a thermal element to turn it off.
If the fan turns off immediately when you switch the stat to "off", then someone may have wired something incorrectly. Most likely you have an older gas furnace with a Fan/Limit combo control. To locate this control take off the front cover and it should be mounted on the rear wall of the unit. It is usually a rectangular gray or silver box, about 2'' by 4". Turn off the power to the unit, usually a switch on the side. Remove the cover and locate the Fan Control. There should be 3 sliding levers for temp setting, on a rotating dial. The one that is set at the lowest temp needs to be raised very slightly to turn the fan off at a slightly higher temperature.
This is just a guess since I would need more info to diagnose completely. Good Luck!

It is only the blower running, and that does not affect your gas bill. The furnace will heat and shut off when the thermostat tells it to. You could see a small increase in your electric bill.
I don't have enough information to troubleshoot your problem, but here is a couple of things to consider. There may be a manual fan switch on your furnace that needs turned off. look for a 2 x 4 inch metal box with a white button that indicates push on - pull auto. Another possibility is a short in the thermostat wire. You can check this by removing the green thermostat wire where it connects to the furnace. If the fan stops, your problem is in the thermostat wire or thermostat. Good Luck

Is the gasoline grew to develop into on?, is the pilot mild lit?, in certain situations there's a swap to practice on/off the warm temperature/cooler, dont comprehend if this can be a cellular or a house, or what kind of furnace, (i.e. gasoline, electric powered, propane), is there a thermostat , or is it a wall hugger, I in simple terms concept-about something as our waterheater did this once. The little piece of versatile cord searching stuff, is termed a thermocouple. the right of this sticks into the pilot mild and opens an inner valve at the same time as it receives warm from the pilot mild. those do move out in many situations, and ought to nicely get replaced for some funds, and also you gadget gained't paintings in the experience that they are undesirable. attempt replacing this universal, and then see iff the pilot mild will paintings, and then turn the gasoline valve something else of ways on. it truly is with somewhat of luck your issue, and they are difficulty-free to modify.

YOU NEED A NEW THERMOSTAT. ABOUT 25.00 AT MENARDS. IF YOU HAVE A/C, THERE WILL BE 4 SMALL WITES ON IT. NO A/C, 2 WIRES. RED WIRE GOES TO R SCREW AND WHITE WIRE GOES TO WHITE. GREEN WIRE TO G SCREW AND BLUE OR YELLOW WIRE GOES TO THE Y SCREW.

Could be a faulty fan limit switch, too.
