Product Details

Description

Ensure your HVAC system operates safely and efficiently with this high-quality 140-degree high limit control switch. Designed as a critical safety component, this thermal fan disc monitors the internal temperature of your furnace or air handling unit. When temperatures reach the 140°F threshold, the switch automatically opens to break the electrical circuit, preventing overheating and potential equipment damage. This reliable replacement part is essential for maintaining proper airflow regulation and system longevity. Ideal for HVAC technicians and homeowners performing furnace repairs, it serves as a vital safeguard for residential and light commercial heating equipment.
