Description
The Goodman B1370150 is an OEM replacement SPST (Single-Pole, Single-Throw) pressure switch engineered for reliable furnace and air handler safety control. Designed with a -0.85″ pressure factor (pf) setpoint and a convenient 1/4″ barbed port connection, this switch monitors the negative pressure generated by the inducer motor to confirm proper venting and combustion airflow before allowing ignition to proceed.
How It Works
The pressure switch senses the differential pressure created by the draft inducer blower. When the inducer establishes adequate negative pressure at the -0.85″ pf threshold, the SPST switch closes to signal the control board that it is safe to continue the ignition sequence. If pressure falls outside the acceptable range — due to a blocked flue, failed inducer, or cracked pressure switch hose — the switch opens, locking out the furnace and preventing unsafe operation.
