Bard S8402-095 Limit Control
The Bard S8402-095 is a critical 190F One Shot Limit Control designed for high-temperature safety within Bard wall-mount air conditioning and heater packages. As a primary thermal cut-off switch, this OEM replacement part is engineered to interrupt the electrical circuit if the heater section exceeds its maximum operating threshold of 190 degrees Fahrenheit. Unlike resettable switches, this "one-shot" high limit control provides a definitive fail-safe; once the internal thermal element open-circuits due to an overheat event, the component must be replaced to restore unit functionality. This ensures that a furnace high limit switch failure forces a technician to diagnose underlying issues such as low airflow, dirty filters, or blower motor malfunctions before resuming operation. It serves as the direct 8402-095 replacement, meeting exact factory specifications for voltage and mounting footprint in Bard HVAC systems. Maintaining an functional HVAC safety limit is essential for protecting the heat exchanger and prevent hazardous equipment conditions.
Key Benefits:- Thermal Protection: Prevents catastrophic equipment damage by providing a dedicated 190°F localized shutdown.
- OEM Compatibility: Serving as the official replacement for 8402-095, it ensures proper fitment and terminal alignment in heater packages.
- High-Reliability Safety: The "one-shot" mechanism eliminates the risk of a technician manually resetting a control on a failing or restricted system.
- Component Longevity: Safeguards expensive heat strips and internal wiring from heat-related degradation.
Is the Bard S8402-095 a manual reset or automatic reset switch?
Neither. This is a "one-shot" thermal cut-off. Once it reaches its 190°F trip point, the internal link breaks permanently, and the part must be replaced.
What causes a 190F One Shot Limit Control to trip?
Common causes include restricted return air, a failing blower motor, or obstructed supply grilles, all of which lead to excessive heat buildup in the heater package.
Can I substitute the S8402-095 with a different temperature rating?
No. In Bard HVAC units, using a higher temperature limit can compromise safety and lead to component melting or fire hazards. Always stick to the 190°F factory spec.
