inducer motor

[unionville]

I have a bryant furnace, model # 312AAV. The inducer motor runs constantly, even when the thermostat is in the the off postion.
When I turn on t-stat to heat the fault code comes up 32 which is pressure switch, changed pressure switch, no luck.
If anyone has come across the same problem, I could use some help.

Thanks

although most furnaces are essentially the same, certain functions may be present in some and some not. when you call for heat, there is a purge delay to exhaust unburnt fuel from the heat exchanger. the inducer fan turns on and a sail switch closes its contacts to set up a burn cycle start. the inducer blower blows air up the chimney to induce a draft for exhaust gases. when the burner starts gases are drawn up and out the chimney. when the stat is satisfied and the heater shuts down, the inducer keeps running for a time delay period. it should shut off after the time delay. look for a timer in your circuit diagram that says inducer motor.

There is a inducer control board behind your pressure switch, that is more than likely your problem.

Thanks for the replies about the braynt furnace, I didn't notice an inducer timer in the electrical diagram, but there is a draft safeguard switch after the inducer motor that I'am going to try and change.
If that does not work then I will change the board and hope that is it.
