This premium 5/8-inch disc limit switch is a vital safety component for residential and commercial heating systems. Designed as a high-limit control, this switch monitors the internal temperature of your furnace or HVAC unit to prevent overheating. The automatic reset feature ensures that once the unit reaches its thermal limit of 220°F, the switch opens to break the circuit, then automatically closes once the temperature drops by 40°F. If your heating system is short-cycling or failing to stay on, replacing a worn-out fan disc switch can restore safe and efficient operation. Built for durability and precise thermal response, this limit control helps protect your appliance from heat damage and ensures long-term reliability.
