    Control Board and Inducer fan replaced in May by another company. Vent sized appropriately, condensate drains are clear. Unit has proper pitch.



    Heats up quickly then shutsdown on error code. Then starts back up.



    Any ideas?

    Check the

    flame rod pull it and clean and re install check the microamp signal should be between 2 to 10 microamps.

    Thanks

    Thanks Tim. Is the flame rod the same as the igniter? Are micro amps AC or DC?

    My bad

    Just re-read your post Tim. You said check amps not voltage. Thanks.

    If the system

    has a hot surface igniter then it may also be used as a sensor or there may be a separate sensor. You are looking to measure DC microamps.
