Amana-Goodman 10728318 Limit Switch

As an HVAC professional, you know that a reliable Goodman furnace limit switch is non-negotiable for system safety and operational integrity. The Amana-Goodman 10728318 Limit Switch is an authentic OEM replacement engineered to monitor and regulate internal plenum temperatures. This L240F-40F limit switch features a 240-degree Fahrenheit fixed "open" set point and a 40-degree Fahrenheit differential for the "close" reset, effectively preventing heat exchanger overheating. Specifically designed for compatibility with Amana and Goodman gas furnaces, such as the GCIB045CA30 series, this primary limit switch ensures the burner circuit opens if airflow is compromised. Its robust construction is designed for high-cycle industrial environments, providing the precise thermal response required to protect the furnace and the structure. Whether you are performing routine maintenance or an emergency service call, utilizing this HVAC high limit control maintains the manufacturer's original safety specifications without the guess-work of universal alternatives.

• OEM Precision: Guaranteed 10728318 limit switch specifications ensure exact fitment and calibration for Amana/Goodman units.
• Optimal Thermal Safety: Fixed 240°F trip point prevents hazardous heat exchanger temperatures during restricted airflow events.
• Industrial Durability: Constructed with heavy-duty components to handle the frequent cycling typical of residential and light commercial HVAC applications.
• Direct Technical Replacement: Eliminates compatibility issues when servicing Goodman furnace parts.

• What does the L240F-40F rating indicate? It means the switch opens (breaks the circuit) when the temperature hits 240°F and automatically resets (closes) after the temperature drops by 40°F.
• Is this switch a manual or automatic reset? This specific model is an automatic reset limit, closing again once the system cools to the differential threshold.
• Will this fix my furnace if it is short-cycling? While a tripped limit is a symptom of overheating, a technician should also inspect the air filter, blower motor, and ductwork for airflow obstructions.
