Bard HVAC 8402-145BX Limit Switch
The Bard 8402-145BX Limit Switch is a critical safety component designed for high-temperature protection in commercial HVAC systems. This Green A/R limit switch features an L230-30 temperature rating, meaning it opens the circuit at 230°F and closes once the temperature drops by a 30°F differential. As a direct replacement for Bard 8402-145, the 8402-145BX ensures seamless compatibility with wall-mount air conditioners and heat pumps without the need for mounting modifications. Veteran technicians recognize this automatic reset thermal limit for its precise calibration and durable construction, preventing heat exchanger overheating or blower failure issues. Whether you are performing routine maintenance or emergency HVAC furnace repair, using this OEM Bard replacement part ensures the unit operates within factory-specified safety parameters. This high-limit cutout switch is essential for maintaining system integrity and avoiding costly damage to internal components in demanding commercial environments.
- Direct OEM Match: Engineered specifically for Bard wall-mount units, serving as the official 8402-145 replacement switch.
- Precise Thermal Control: Features a fixed L230-30 setpoint for reliable overtemperature protection.
- Automatic Reset Functionality: The Green A/R switch restores circuit continuity automatically once temperatures stabilize, reducing unnecessary service calls.
- Compact Form Factor: Designed for standard electrical bracket mounting, ensuring a quick swap during HVAC field service.
Common Service Questions
Is the 8402-145BX compatible with older 8402-145 models?
Yes, the 8402-145BX is the verified HVAC manufacturer direct replacement for the legacy 8402-145 part number, maintaining the same electrical specs and physical dimensions.
What does the L230-30 rating indicate for this switch?
This signifies the switch is a normally closed thermal limit that opens at 230 degrees Fahrenheit and resets when the temperature cools to 200 degrees Fahrenheit.
Why would my Bard unit keep tripping this limit switch?
Frequent tripping usually indicates restricted airflow, often caused by a dirty HVAC filter, a failing blower motor, or blocked return air grilles.
