When the room thermostat is satisfied it stops the heat by stopping power to the sequencer or contactor which is in series with the heating element/s...the TEMPERATURE OPERATED FAN SWITCH then takes over the blower until the heaters cool

True air heat tries to start then goes to gas.It worked fine in the fall but it is now -5F


Do you have a heat pump and gas furnace setup? Or is it electric and gas setup.

To me it sounds like either configuration issue its electric and gas, but if its heat pump/gas the furnace is defaulting to gas more then likely on the outside air temperature, usually most heat pumps only heat good down to 10 degrees F.

I'm not sure whether this is a gas unit or not. With many gas heaters, the blower comes on when the heat exchanger gets hot enough and goes off once the heat exchanger cools. Other things are happening before the blower goes on. The blower is normally controlled by a "fan control thermostat". This stat actuates the blower when the furnace is hot enough so that cold air is not being blown around and allows the blower to run until the furnace cools enough to get out the remaining heat after the flame shuts off but not so long to again allow cool air to blow around. If this fan control is malfunctioning, you will get erratic runs from the blower or the blower may not run at all or run long or continuously. The fan control is the first thing to check.

Furnace blower won't turn on... Forced air gas furnace was working fine for three weeks. Now: Turn themostat up Gas comes on, pilot light obviously working Box heats up for about 90 seconds Humidifier...


If it indeed started that one time for a short period then cut out, the first place that I would start would be the capacitor located in the blower compartment. The capacitor gives the motor the need kick to start, and often times stays in the circuit to help the motor run more effeciently. This could very well be the problem.

If you have the option to run the fan from the thermostat, turn the fan to the "on" position and see if it starts. If it does, then it is not the capacitor.

Hope this helps

PS Your are correct about the "sensor" turning the furnace off, it is called a high limit switch and is there for safety. It is an automatic reset device, and will reconnect power once it has cool suffeciently.

Sounds like the rollout is being tripped from the blower moving the falmes. i would have your heat exchanger checked for cracks or holes as this is usually the reason the blower moves the burner flames to tripp a rollout.

Can I convert a propane furnace to electric?


Actually yes! You can install electric elements in the plenum that turn on by your thermostat. The convection blower from the furnace can be used. You can also install a heat pump system that will give you both heat and air conditioning.

I replaced my Janitrol 7 wire thermostat with an RTH7500 which now controls my heatpump system. The switches on the Janitrol were cool - off - heat - Em Heat. Does that mean I have auxiliary heat? There is...


There should be electric heat strips in the airhandler.

They automatically come on when the unit goes into defrost, the thermostat is turned up more than 7 degrees over the indoor temp or if the outdoor temp is just so cold the HP cannot keep up.

Tat is your auxillary or emergency heat.

What does the new t-stats installers booklet say that the 0170 function and #2 #7 options are for?

If it is for gas vs elec heat then set it on the elec option.

The difference is that in gas heat systems the blower comes on a few min AFTER the furnace fires up to allow the heat exchanger to get hot.
In an electric furnace the blower has to come on emediatly because the heat strips get hot emediatly and if the blower is delayed the system will shut of in high temp overload.
