The L160-30F High Limit Switch is a critical safety component designed for forced-air heating systems and furnaces. This 3-inch limit control sensor monitors the internal temperature of the heat exchanger, acting as a vital fail-safe by automatically cutting power to the burner or heating elements if the unit exceeds safe operating limits. This specific switch is engineered to open the circuit at 160°F and features a 30°F differential, meaning it will reset once the system has cooled to a safe temperature. If your furnace is short-cycling or failing to stay on, a malfunctioning thermal limit switch may be the cause. This durable replacement part ensures your HVAC system operates efficiently while preventing overheating and protecting your home from fire hazards.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
