Product Details

Description

This premium 5-inch insert high limit control switch is a vital safety component for residential and commercial heating systems. Engineered as an L240F-30 thermal limit, this thermostat monitors internal furnace temperatures to prevent hazardous overheating. When the system reaches the critical 240°F threshold, the switch automatically opens to interrupt the heating cycle, protecting the heat exchanger and surrounding components from damage. Once the temperature cools by its 30°F differential, it resets to restore normal operation. Ideal for HVAC maintenance and furnace repair, this durable limit control ensures your heating equipment operates within safe temperature parameters.
