Hi All, I have a 5 y/o 80% eff bryant furnace. The problem I have is that my furnace Doesn't always kick on even when thew thermostat shows the temp under the Temp set. I will sometimes have to go down and turn of the blower switch on the furnace wait a couple seconds and then turn it on again....

Furnace operates fine except during cycle it will shut down then come back on to complete cycle. Could this be the blower relay or something else?

My carrier furnace would only come on if I shut down the main power then turned it back on. Then after it got up to the proper temperature it would shut off but not come back on. Now it won't come on at all. I just replaced the control board and it is doing the same thing.

My furnace is 5 years old. Will not stay lit. The igniter lights, the gas valve open, stays on for 30 seconds and shuts down and does it over and over. Never staying operational. Please help.

I have an old coleman electric furnace which is not working properly. The problem is that when the blower will quit when it is supposed to but the heating coils keep heating no matter what I do with the thermostat. I have had to cut the unit off at the breaker to stop the unit from heating. Any...
