This professional-grade Disc Limit Switch is a vital safety component for residential and commercial heating systems. Designed as an automatic reset high-limit control, this sensor monitors the internal plenum temperature of your furnace or air handler to protect against overheating. When the system reaches the pre-set temperature of 215°F, the switch opens to interrupt the heating cycle, preventing damage to the heat exchanger and ensuring safe operation. Once the unit cools by 30°F, the switch automatically resets to restore functionality. This durable fan disc switch is a common replacement part for HVAC systems experiencing short-cycling or ignition issues, providing a reliable solution for maintaining optimal climate control and equipment longevity.
