Modine OEM Replacement Pressure Switch
The Modine 5H0750300004 is a factory-specified SPST (Single-Pole, Single-Throw) pressure switch rated at 0.40″ water column (WC). Designed as a direct OEM replacement for compatible Modine unit heaters and make-up air heating equipment, this pressure switch monitors combustion air or draft pressure to verify safe operating conditions before and during burner operation.
How It Works
The pressure switch senses negative or positive air pressure within the heat exchanger or venting system. If the measured pressure falls outside the rated setpoint — indicating a blocked flue, failed inducer motor, or inadequate combustion airflow — the switch opens the circuit to prevent unsafe burner operation, protecting both equipment and occupants.
