Ensure the safety and efficiency of your heating system with this high-quality Goodman/Amana Primary Limit Switch. Designed as a critical high-limit control, this L150-30F fan disc switch serves as a vital safety mechanism for residential gas furnaces and HVAC units. It is engineered to monitor the heat exchanger's temperature, automatically interrupting the heating cycle if the internal temperature reaches 150°F to prevent overheating and potential equipment damage. The switch features a 30°F differential, allowing the system to reset once the temperature safely drops to 120°F. If your furnace is short-cycling, the blower fan is running constantly, or the system fails to stay lit, a faulty limit control switch may be the cause. This durable replacement part helps maintain reliable climate control and protects your forced air system from thermal stress.
