The 155-55F Auto Reset Limit Switch is a critical safety component designed for high-performance heating and ventilation systems. Functioning as a high-limit control, this fan disc switch monitors internal temperatures to prevent equipment overheating and potential damage. When the temperature reaches the 155°F safety threshold, the switch automatically opens the circuit to cut power to the heating element or burner. Featuring a 55°F differential, this thermal cutout automatically resets once the appliance cools down to a safe operating temperature, restoring functionality without manual intervention. This durable, precision-engineered switch is a common replacement part for furnaces, electric heaters, and forced-air HVAC systems, ensuring both appliance longevity and household safety.
