Ensure the safe and efficient operation of your heating system with this 170-degree Fahrenheit Primary High Limit Switch. As a critical safety component for residential furnaces and air handlers, this fan disc-style control switch is designed to monitor the temperature within the heat exchanger cabinet. If the internal temperature exceeds the 170°F threshold, the switch automatically interrupts the electrical circuit to the burner or heating element, preventing potential overheating and equipment damage. This durable replacement part is essential for maintaining HVAC system safety and is a common fix for furnaces that are cycling improperly or shutting down prematurely. Built for reliability, this limit control helps protect your appliance from thermal stress and ensures your central heating system operates within safe temperature parameters.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
