Carrier 338096-710 Limit Switch Assembly
The Carrier 338096-710 Limit Switch Assembly is a critical safety component designed for precise thermal monitoring in residential and commercial gas furnaces. This genuine OEM Carrier replacement part functions as a primary high-limit control, featuring a normally closed (NC) circuit that triggers a system shutdown if internal plenum temperatures exceed safe operating parameters. Engineered to professional standards, this main limit switch ensures the heat exchanger does not exceed critical thermal limits, protecting both the equipment and the structure from potential overheating hazards.
Specifically calibrated for high-limit protection, the assembly is rated at L220-20F, meaning it is designed to open on temperature rise at 220°F and automatically reset when the temperature drops to 200°F. This automatic reset limit switch includes a pre-installed gasket to maintain an airtight seal within the furnace cabinet, preventing air leakage and ensuring accurate temperature sensing. It serves as a direct replacement for Carrier, Bryant, and Payne units, offering the reliability required for rigorous HVAC service calls and long-term system integrity.
Key Benefits:
- Precise Thermal Protection: Calibrated to open at 220°F to prevent heat exchanger damage and unsafe operating conditions.
- Factory-Authorized Performance: An authentic Carrier furnace part that maintains the original equipment’s airflow and safety specifications.
- Simplified Installation: Includes the necessary mounting gasket for a secure, professional-grade seal.
- Automatic Reset Logic: Eliminates the need for manual intervention once the system returns to a safe 200°F operating temperature.
- Broad Compatibility: Fits a wide range of forced-air heating systems across the Carrier Corporation family of brands.
Common Questions:
What causes a main limit switch to trip frequently?
Repeated tripping is usually indicative of restricted airflow. Technicians should inspect for a dirty air filter, blocked return air ducts, a failing blower motor, or a cracked heat exchanger before replacing the switch.
Can I use a switch with a different temperature rating?
No. Using a limit switch with a higher or lower opening point can compromise system safety or cause nuisance tripping. Always match the L220-20F rating specifically for this application.
Is the gasket included with the 338096-710?
Yes, this assembly comes with the required gasket to ensure an airtight seal against the furnace plenum.
