Description

Ensure the safety and reliable operation of your heating system with this high-quality L170-40F Auto Reset Limit Switch. As a critical high-limit control component, this fan disc switch monitors internal temperatures to prevent HVAC equipment from overheating.

This replacement part is ideal for restoring proper thermal regulation in residential and commercial heating systems, protecting against damage caused by restricted airflow or blower failure.
