Job Checkin

Arrived to find control board flashing code 31 for pressure draft safe guard. Checked vent for any obstruction and found none. Found pressure switch to be stuck open. Blew into it to close it and started ignition sequence. Furnace fired up and is operating correctly at this time. Turned furnace on and off several times to test that issue did not persist.
