Who Needs Heat?
A few weeks ago my furnace stopped working. The fan would come on, the flames would light the burner but the large blower would not turn on to blow the air throughout the house. However it would work if i switched the thermostat from "auto" to "on" but this meant that the blower would run constantly.
There are a lot of pieces in there. The blower is the big metal thing at the bottom.
So after a week of reading online i figured it had to be one of these things:
The shorted out board behind the blower relay switch.
I soldered the wire back to the connector, hooked everything back together and amazingly enough it worked, the blower came on when it was suppose to.

So after a week of reading online i figured it had to be one of these things:
- blower control board
- heat sequencer
- temperature limit switch
- fan limit control switch
- temperature sensor
- relay switch
