Product Details

Description

This automatic reset high limit control switch is a critical safety component designed for HVAC systems and forced-air furnaces. Functioning as a fan disc thermal cutout, this switch monitors the internal temperature of your heating equipment to prevent overheating. When the temperature reaches the pre-set high limit of 130°F, the switch automatically opens the circuit to shut down the burner or heating element, protecting the appliance from heat damage. Once the system cools back down to 100°F, the switch resets itself to restore normal operation. This durable, snap-action disc switch is essential for maintaining safe operating temperatures and extending the lifespan of residential and commercial heating units.
