Product Details

Description

This 3-inch high limit switch is a vital safety component designed for residential and commercial heating systems. Functioning as a thermal safeguard, this high limit control switch monitors the internal temperature of your furnace or HVAC unit to prevent overheating. When temperatures exceed the safe operating threshold, the switch automatically interrupts the electrical circuit, protecting your equipment from damage and ensuring home safety. Featuring a reliable temperature setting with a built-in differential for automatic resetting, this component is a common replacement part for malfunctioning blowers or heating cycles. It is an essential repair part for maintaining the efficiency and longevity of forced air heating systems.
