Carrier HH22HB067 T-Stat

The Carrier HH22HB067 T-Stat is a genuine OEM replacement temperature actuator switch designed for precision thermal regulation in compatible Carrier, Bryant, and Payne HVAC units. As a high-reliability limit switch, this component ensures safe equipment operation by monitoring internal temperatures and executing circuit interruptions when thermal thresholds are exceeded. For contractors and technicians, utilizing an authentic Carrier replacement part like the HH22HB067 is critical for maintaining the factory-specified safety parameters and operational integrity of the primary heating or cooling system.

This HVAC temperature switch features a robust design capable of withstanding the high-cycling demands of commercial and residential environments. It is specifically engineered to interface with the original control board logic, providing seamless system compatibility without the need for field modifications. When diagnosing short-cycling or thermal lockout issues, replacing a fouled or drifting limit control with this OEM actuator restores the unit to its optimal performance curve. Ensure your HVAC maintenance inventory includes these essential safety devices to minimize downtime and prevent catastrophic component failure in high-output forced-air systems.

• OEM Precision: Guaranteed Carrier HH22HB067 specifications for exact setpoint accuracy.
• Universal Compatibility: Fits a wide range of Carrier, Bryant, and Payne models including the 50BT and 38 series.
• System Protection: Acts as a critical safety limit switch to prevent overheating and equipment damage.
• Direct Fit: Designed for rapid installation with standard lead connections, reducing labor time on the job site.

Is the HH22HB067 a universal limit switch?
While it fits dozens of 50BT and 38-series models, it is a specific OEM Carrier part. Always verify the opening/closing temperature setpoints against your specific model's service manual to ensure proper safety circuit integration.

What are the symptoms of a failing temperature actuator?
Common indicators include intermittent system lockouts, the inducer motor running without ignition, or the unit tripping on a "Limit Switch Open" fault code. Replacing with a genuine HH22HB067 solves these issues if the switch has drifted out of calibration.

Can I use this switch in both heating and cooling applications?
Yes, this temperature actuator switch is utilized across various equipment types where thermal monitoring is required. Consult the unit’s wiring diagram to confirm it matches the required normally-closed (NC) or normally-open (NO) configuration for your specific application.
