Reznor 207178 Pressure Switch

Reznor 207178 Pressure Switch

When you're troubleshooting a Reznor unit and the burner refuses to fire, the Reznor 207178 Pressure Switch is often the first place to check. This 0.20" WC pressure switch is a critical safety component designed to verify that the inducer motor is creating the proper negative pressure before allowing the ignition sequence to proceed. As a genuine Reznor OEM replacement part, it ensures your heating equipment maintains factory-spec safety standards and operational efficiency in demanding commercial or industrial environments.

The 207178 pressure control features a precise diaphragm calibrated exactly to a 0.20-inch water column setpoint. This sensitivity is vital for detecting subtle airflow obstructions or venting issues that could lead to incomplete combustion. Its SPDT configuration provides reliable switching performance, while the rugged construction is built to handle the cycling and temperature fluctuations common in unit heater applications. For any technician, keeping a HVAC induction pressure switch like this in the van is standard practice for quick, reliable repairs on Reznor systems.

Key Benefits
  • Precise 0.20" WC Calibration: Ensures the system only ignites when the correct negative pressure is achieved, preventing hazardous operation.
  • Genuine Reznor OEM Part: Guarantees a direct fit and seamless electrical integration with existing Reznor control boards and wiring harnesses.
  • Industrial-Grade Durability: Constructed to withstand the harsh conditions of warehouse and mechanical room environments.
  • Safety Lockout Integration: Correctly signals the control board to enter lockout mode if venting or inducer performance drops below safe thresholds.
Common Questions

How do I know if the 207178 pressure switch is failing?
If the inducer motor runs but the igniter never glows, use a manometer to verify the draft. If the draft exceeds 0.20" WC but the switch remains open, the internal diaphragm or electrical contacts may be fouled.

Can I use a universal pressure switch instead of the 207178?
While universal switches exist, they often require manual calibration. Using the Reznor 207178 ensures the 0.20" WC setpoint is factory-accurate, maintaining the system's UL certification and safety profile.

What causes a "Pressure Switch Stuck Open" error code?
This is frequently caused by a cracked pressure switch hose, a blocked flue vent, or a failing inducer motor that cannot pull the required 0.20" WC vacuum.
