Product Details

Description

This high-limit control switch is a vital safety component for HVAC systems, designed to prevent furnaces and air handlers from overheating. Featuring a 3-inch insert probe, this switch monitors internal plenum temperatures to ensure the system operates within safe thermal parameters. If the temperature exceeds the pre-set safety threshold of 215°F, the switch automatically breaks the electrical circuit to shut down the burner or heating element, protecting the equipment from damage and enhancing home safety. It is engineered to reset once the temperature drops by 30°F. Ideal for professional HVAC repairs and maintenance, this durable limit control ensures reliable performance and longevity for residential and commercial heating units.
