Yes, inspect the air intake, exhaust pipe, filter and condensate piping for blockage or moisture. Also check for a hole in the hose that goes from the small exhaust blower to the pressure switch or a bad connection on the switch or control board. You may be able to temporalily jump the switch for diagnostic purposes only.

Hi Kim,
A couple things to check:

1) OK, you've replaced the pressure switch - good stuff. But the neoprene hose running from the pressure switch to the inducer motor... does it have any tears or cracks? Is the hose fittings clogged on the inducer side? Clean/replace as necessary if so. You cannot have any leaks or restrictions in this hose.

2) Try disconnecting the inducer (spent fumes exhaust fan) motor and check this motor coil for continuity with a multimeter. If the motor coil is dead, you'll need to replace the inducer (about $120.00?).

3) Check during initial startup of a heating cycle that there actually is 120vac arriving at the inducer motor coming in from the control board. If not, your board may be at fault.

Hope this helps!
