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
Any comments will be appreciated

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 .

Must be a limit or rollout. Pressure switch

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

You absolutely right however there is no limit on the way but three rollout arount the burner box which are all OK and no problems .
Tks for quick answer again .

Does the control board give a fault?

No not at all . There is no led on the control board . However I replaced it with a new one and the problem still there .

remove the draft motor and the tube to the P/S. make sure its free from moisture and shake the draft motor to be sure there is no water collecting in it.
