Bard 8402-144BX Switch
The Bard 8402-144BX Switch is an OEM high-limit safety control engineered for precise thermal monitoring in Bard HVAC systems. This L150-30 exposed face auto-reset switch is calibrated to open the electrical circuit when the supply air temperature reaches 150°F, effectively shutting down heating elements to prevent heat exchanger damage or cabinet overheating. Once the internal temperature drops by 30°F (reclosing at approximately 120°F), the automatic reset engages to restore normal operations, reducing the risk of nuisance lockouts in high-demand environments. Featuring a 0.50-inch insertion depth and an orange color-coded face for rapid identification, this genuine Bard replacement part ensures complete compatibility with existing mounting brackets and wiring harnesses. As a critical safety component, it maintains the integrity of the HVAC high-limit circuit and protects against restricted airflow issues commonly caused by clogged filters or blower failures.
Key Benefits:
- Precise Thermal Protection: Engineered with a fixed L150-30 temperature rating to safeguard the heat exchanger from excessive thermal stress.
- Automatic Reset Functionality: Eliminates the need for manual intervention by resetting the circuit once the system cools to a safe 120°F threshold.
- OEM Engineering: A genuine Bard 8402-144BX component, ensuring exact electrical specifications and physical fitment without field modifications.
- High-Visibility Identification: The orange exposed face allows technicians to quickly verify the temperature rating during troubleshooting and maintenance.
- Rugged Reliability: Built to withstand the high-cycle demands of commercial and residential wall-mount units.
Common Questions:
What is the difference between 8402-144 and 8402-144BX?
The "BX" suffix is a packaging designation used by Bard; the technical specifications and performance characteristics are identical, and they are direct replacements for one another.
Why is my Bard high-limit switch tripping frequently?
A trip indicates the sensor is detecting temperatures above 150°F. Before replacing the switch, verify that the air filter is clean, the blower motor is operating at the correct RPM, and there are no obstructions in the supply or return ductwork.
Can I use this switch in place of an L145 or L160 limit?
No. Safety controls must always be replaced with the exact temperature rating specified by the manufacturer. Installing a different rating can lead to system damage or unsafe operating conditions.
