Product Details

Description

This premium 3-inch high limit switch is a vital safety component designed for residential gas furnaces and HVAC heating systems. Engineered to protect your equipment from overheating, this thermal limit control monitors the heat exchanger's temperature. If the internal heat exceeds safe operating levels, the switch automatically interrupts power to the burner or heating elements, preventing damage and ensuring household safety. This reliable replacement sensor features a 200-degree Fahrenheit trip point and a 30-degree differential, making it an essential part for restoring proper cycling and function to a malfunctioning furnace. Ideal for HVAC technicians and DIY homeowners looking to repair heating units that are cutting out or failing to maintain consistent air temperatures.
