    Bryant furnace draft motor spins, but HSI doesn't heat, no ignition
    The title pretty much says it... the circuit board is United Tech Electronic Controls HK42FZ010 and it's giving LED code 4 short, 3 long. I see from another post that this is "Low-heat pressure, draft safeguard, or auxiliary limit switch open while high-heat pressure switch closed", but I have no idea what to do next. Help, anyone?

    More information... I can see both of the vacuum valves opening & shutting when I turn it on & the draft motor begins running. We had some high winds recently and I'm wondering if that could have tripped the draft safeguard, but I don't know where that is.

    Can't find much on that furnace. Can you post a pic of the wiring diagram? Yes high wind's can cause a problem.
