Aaon G006390 Pressure Switch

The Aaon G006390 Pressure Switch is a high-limit safety control designed for precise refrigerant circuit monitoring in commercial HVAC systems. This high pressure switch 375# M/R is engineered with a manual reset function, ensuring the system remains offline following a high-pressure event until a technician can diagnose the root cause. As a direct replacement for Aaon 29635, this component ensures seamless mechanical and electrical compatibility within Aaon rooftop units and chillers. The HVAC high pressure cutout is calibrated to trigger at 375 PSI, protecting the compressor from thermal overload and catastrophic failure due to restricted airflow, overcharge, or condenser fan failure. Utilizing a robust refrigerant pressure switch like the G006390 is critical for maintaining system integrity and meeting commercial HVAC pressure switch specifications. Its durable construction withstands the vibrations and temperature fluctuations common in industrial environments, providing reliable OEM Aaon parts performance for demanding service applications.

• Direct Fit Replacement: Engineered specifically to replace legacy part number 29635 without mounting modifications.
• Safety Compliance: Features a manual reset (M/R) mechanism to prevent short-cycling after a high-pressure trip.
• Precise Calibration: Factory-set at 375# to ensure accurate system protection under high-load conditions.
• Durable Construction: Built for high-cycle reliability in demanding commercial HVACR environments.

What is the reset logic for the G006390?
This is a manual reset switch. Once the pressure drops below the reset threshold, a technician must physically depress the reset button to close the circuit and allow compressor operation.

Can this replace other 375 PSI switches?
While the pressure rating may match, the G006390 is optimized for Aaon equipment. Always verify thread pitch and electrical terminal configuration before installation.

Is the G006390 compatible with R-410A systems?
Yes, the 375 PSI setpoint is typically utilized in specific high-side protection circuits; verify your system's design operating pressures against the 375# rating.
