Product Details

Description

This premium fan and limit control switch is a vital safety and operational component for HVAC heating systems and furnaces. Engineered with a 'close on rise' configuration, this disc-style switch automatically completes the electrical circuit when the temperature increases to the specified range, typically used to activate the blower fan once the heat exchanger has reached the proper operating temperature. Beyond fan regulation, it serves as a critical high-limit safety device, protecting your heating equipment from potential damage caused by overheating. This durable replacement part ensures efficient heat distribution and reliable system performance, making it an essential component for routine furnace maintenance and HVAC repairs.
