Product Details

Description

This high-limit control switch is a critical safety component designed for heating and cooling systems, including residential furnaces and HVAC units. As a thermal fan disc, its primary function is to monitor internal temperatures and interrupt power to the heating element if the system exceeds safe operating limits. This specific model is engineered to open at a fixed temperature of 150°F and features a 30°F differential, meaning it will reset and close the circuit once the temperature drops to 120°F. Reliable and durable, this switch prevents equipment damage and ensures safe operation by acting as a fail-safe against overheating. It is an essential replacement part for maintaining the performance and safety of gas or electric forced-air heating systems.
