repost with more specific . motor aka fan is running?stat is set to heat and max heat? how old? general progression is as follows. stat says its cold. signal is sent to gas valve to open. gas valve looks to see if pilot is lit via thermocouple. if pilot is lit then main valve opens and burner lights. shortly thereafter sufficient heat builds up to trip heat sensor that turns on fan and blows hot air into house.many times a tripped safty causes a default fan response. aka when you show up the fan is on 24 7 . that equals a failed safety and needs a pro tech to see why saftyfailed.

does the furnace ignite?? your system may not have been lighting and has gone into ignition lockout count the codes of the led lights then remove panel led diagnostic codes are listed there.
if led codes indicate no problem verify capacitor is good and that mtr is getting 115 volts.

I had the same problum with my heater to no end. I thought it was the th-sat . still don't know if it was . one of the sencers I was feeling, and the disc snapped in and the heater ran but on heat. turn off power and unplug the power cord and removed the sencer and taped it until it pop back out and when it did I resemble back in place.repluged all back up. turn the heater back on and the flame stayed on . LET THEIR BE HEAT. I played with it for 4 hrs.I don't know if this was the problum .will have a teck look at it to be safe.

There is no pilot and the flame is lit by a hot surface ignitor...
The hot surface ignitors go bad frequently...you probably need to replace that...
Here is a tip that will help you try to figure out why your furnace is notworking.
