Sounding like a flame proving device is failing to sense flame. Try to clean the device with some steel wool. It is located right next to the last burner looks like a thick wire. Take the steel wool and gently rub the carbon that has built up off. Should only take 4 or 5 strokes. Let me know it that did it. Ken

Your induce fan motor is burnt out or the senor is out. If the little fan is working its just the senor. Your going to need a repairman to find the senor or motor for you. You can replace the senor but I wouldnt recommend replacing the motor. www.fastacservice.com

Normally if you have a limit switch problem on a hot air furnace it is the manual high limit switch that should be located near the blower. If you lost power while the unit was operating the heat build up will trip this switch.
Normally they are about 2 inches round with a red button in the center. Firmly push the button till it clicks.
Sometimes it can be the high limit switch that is just a saftey switch in case the furnace gets too hot.
If you do not have enough air flow this switch will operate excessively and will eventually fail.
The best way to find the problem is to trace the low voltage control circuit till you find the open switch. This can be challenging and time consuming, especially if you are not used to doing it.
I hope that this will help you to solve your problem!
Thanks for using Fixya!!

This happens when the furnaces tries to light to many times and doesnt succeed. If you stand in front of the furnace while it is coming on, you will be able to hear the problem. If its an electronic start, there will be a clicking sound, followed by the gas valve opening to start it. If it has a pilot light, make sure it is lit, then listen for the gas to come out, it will make a hissing sound. If no gas is coming out, first double check to see if the gas is turned on to the unit, if it is, then its possibly the gas valve. Oh, if it is electronic, and you hear gas, but dont see a glow inside the furnace, or no glow or gas, it could be the ignite. Hope this helps.

1) Turn the fan to on and if it runs you know that you have line
voltage to furnace and 24volts to the thermostat.
2) You could turn the furnace off remove the doors and get to the
control board. If you can find the Thermostat wires on the board
mark and remove them. If you have a typical Furnace and you
have some electrical background put a jumper wire between
terminals R and W,put the doors back on-there is a door switch
that if the panel is not put back on-it will not run. Turn your power
3) The Blower motor may come on, the induced draft blower should
come on, the glow coil should glow, the gas valve open and the
burners should come on and the unit should run.
4) If all of this happens, then you have a thermostat problem or you
have bad thermostat wires.
5) If nothing happens then you don`t have power to the furnace or the
little fuse that protects the transformer is blown.
