Modine 5H0716080008 Pressure Switch

The Modine 5H0716080008 Pressure Switch is a critical safety component designed for precise draft monitoring in high-efficiency heating systems. This SPST (Single Pole Single Throw) vacuum switch is factory-calibrated to a .45" WC (Water Column) set point, ensuring the inducer motor is moving sufficient combustion air through the heat exchanger before ignition. As the direct replacement for Modine 5H71608-8, this OEM part maintains the operational integrity of your unit heater without needing field modifications.

For technicians on a service call, the 5H0716080008 features a 1/4" barb connection for standard sensing tubing and common spade terminals for HVAC pressure switch wiring. This component is frequently utilized in the Modine 3H0333310002 ventor assembly and is compatible with several PDP and HD series unit heaters. Using this Modine replacement part ensures the system meets the exact static pressure requirements specified by the manufacturer, preventing nuisance trips or unsafe combustion conditions caused by generic alternatives.

• Precise .45" WC Calibration: Maintains tight tolerances for reliable proof of airflow in draft inducer circuits.
• OEM Compatibility: Serving as the technical successor to the 5H71608-8, it fits existing brackets and wiring harnesses.
• Industrial-Grade Construction: Built to withstand the high-temperature environments of gas-fired unit heater cabinets.
• Standardized Porting: Features a high-integrity 1/4 inch barb for a secure vacuum hose seal.

What happens if the pressure switch fails to close?
If the Modine inducer pressure switch remains open, the ignition control will lock out to prevent a startup without proper venting. Ensure the sensing tube isn't cracked and the .45" WC threshold is actually being met by the blower.

Is this switch field-adjustable?
No, the 5H0716080008 is a fixed-point switch. Attempting to adjust the set point can lead to unsafe operation; always replace with the specific WC rating required by the model plate.

Can I use this for other brands?
While it is an SPST pressure switch, it is specifically engineered for Modine draft inducer specifications. Cross-referencing by set point alone is not recommended without verifying the electrical load ratings.
