This high-performance high-limit control switch is a vital safety component for residential and commercial heating systems. Functioning as a fan disc limit, it monitors the internal temperature of your furnace or air handler to prevent dangerous overheating. If the heat exchanger reaches its maximum safety threshold of 220°F, the switch automatically interrupts the circuit to the heating element or burner, protecting the appliance from heat damage and ensuring safe operation. Once the temperature drops to a safe level of 190°F, the control resets to allow for normal operation. This reliable replacement part is essential for HVAC maintenance, providing peace of mind and extending the lifespan of your heating equipment.
