    Kenmore two stages problems
    Kenmore furnace two stages
    M/N : C9MPT07514A3
    G/V smart valve 9541

    Call for heat there , the furnace kicks on however the inducer goes off half way that means when it is going to light up the HSI .
    Checked out the board that is OK
    Checked out the inducer is OK
    Checked out the blower fan that is OK
    P/S closed and shows 24vac on airflow C and NO

    Kenmore two stages
    M/N :C9MPT100J16B1
    G/V smart valve SV9541

    Replaced the smart valve and now come across a big problem:

    Call for heat is there , the furnace is humming however the inducer does not get energized . Waited for more than 5 minutes and no go at all.
    The inducer found to be OK
    The blower OK
    The board was replaced with a new one and the problem still there .

    Any comments will be highly appreciated .

    The only thing that would stop the vent motor is a limit, or loss of heat call
