Field Controls 602602001 Pressure Switch
The Field Controls 602602001 Pressure Switch is a high-precision sensing component specifically engineered for use with PVG-100 power venters. As a critical safety interlock, this SPST pressure switch monitors the negative pressure generated by the blower to ensure proper combustion air volume before allowing the burner to fire. Designed for induced draft systems, it features an 8" WC set point with built-in differential hysteresis to prevent rapid cycling and ensure stable operation during long heating cycles. This OEM-spec part provides a direct replacement for failed units in gas furnaces, boilers, and water heaters that utilize Field Controls power venting technology. The robust diaphragm-actuated design is built to withstand the vibrating environments of mechanical rooms while maintaining accurate pressure sensing. For technicians performing HVAC system troubleshooting, this Field Controls replacement part restores the necessary safety parameters to the integrated furnace control board, preventing hazardous conditions like carbon monoxide buildup or blocked vent errors.
Key Benefits:
- OEM Compatibility: Precision-calibrated for seamless integration with Field Controls PVG-100 venting units.
- Enhanced Safety: Acts as a reliable combustion safety interlock, preventing burner activation without verified airflow.
- System Longevity: High-cycle diaphragm construction ensures consistent performance across residential and light commercial heating applications.
- Diagnostic Accuracy: Standardized electrical terminals allow for rapid testing with a manometer and ohmmeter during preventive maintenance.
Common Questions:
How do I verify if my Field Controls 602602001 has failed?
Use a manometer to measure the actual pressure at the switch port while the inducer is running. If the pressure exceeds the set point (stamped on the housing) but the SPST contacts remain open (infinite resistance), the internal diaphragm or microswitch is likely compromised and requires replacement.
What causes this pressure switch to trip during a cycle?
Common system-side causes include a blocked vent pipe, a failing inducer motor, or moisture accumulation in the sensing tubing. In condensing furnaces, ensuring the proper 1/4" per foot slope on horizontal vent runs is essential to prevent condensate from backing up into the pressure switch body.
Can I use this switch as a universal replacement?
No. Pressure switches are application-specific based on the required "inches of water column" (WC) rating. Using a switch with an incorrect set point can lead to unsafe burner operation or frequent furnace fault codes.
