Modine 5H0716080009 Pressure Switch

The Modine 5H0716080009 Pressure Switch is a critical OEM safety component designed for precise 0.82" WC airflow verification. This SPST pressure switch acts as a primary safety interlock, ensuring that the inducer motor is generating sufficient static pressure to vent combustion gases safely before allowing the ignition sequence to proceed. As the direct factory replacement for Modine 5H71608-9, it maintains the exact calibration required for high-efficiency unit heaters and duct furnaces.

Built for the rigors of commercial and industrial HVAC environments, this switch utilizes a sensitive diaphragm to detect minor pressure differentials. For technicians, installing a genuine Modine 5H0716080009 ensures seamless compatibility with existing harness connectors and mounting brackets, preventing the nuisance trips or delayed firing often associated with non-spec universal alternatives. This HVAC pressure switch is essential for restoring the safety logic and operational integrity of Modine heating systems.

Key Benefits

• OEM Precision: Factory-calibrated at 0.82" Water Column to meet strict safety and venting specifications.
• Direct Compatibility: Engineered as the official successor to part number 5H71608-9 for a drop-in replacement.
• Reliable Switching: Features a durable Single Pole Single Throw (SPST) contact configuration for consistent signal feedback.
• Safety Optimized: Critical for monitoring flue gas passage and preventing operation under restricted venting conditions.
• Rugged Construction: Designed to withstand the thermal cycling and vibration found in gas-fired unit heaters.

Common Questions

Can I use a universal pressure switch instead of the 5H0716080009?
While universal switches exist, Modine airflow switches are safety-critical components. Using a part not calibrated to the exact 0.82" WC set point can lead to unsafe operation, improper venting, or frequent system lockouts.

How do I confirm if my current switch is failing?
Technicians should check for continuity across the SPST contacts once the inducer reaches full speed. If the switch remains open despite the system reaching the proper pressure, or if the diaphragm shows signs of moisture or cracking, replacement is necessary.

Does this switch include the necessary tubing?
This is the OEM replacement pressure switch assembly. It is recommended to inspect the existing sensing lines for cracks or blockages and reuse or replace them with high-temperature silicone tubing as required by the specific Modine model.
