    Day and night plus 80 furnace 33 / 12 Code
    My furnace ignites, heats for a couple minutes, the blower does not come on, it shuts down then flashes a 33 code than a 12 code. I have pulled the wires off the limit switch and held them together to bypass, pulled out the switch and tapped it but when I try to fire it up, it just goes into 12 code. What's up?
