The YORK/ETC Limit Switch L150-30F AUTO is a critical safety component designed for residential and commercial HVAC systems, specifically furnaces and air handlers. This high-limit control switch, often referred to as a fan disc, monitors the internal temperature of your heating equipment to prevent overheating. When the system reaches a temperature of 150°F, the switch automatically breaks the electrical circuit to shut down the heating element or burner, protecting your appliance from thermal damage and ensuring home safety. Featuring an automatic reset, the switch restores connectivity once the temperature drops by 30°F. This durable replacement part is essential for maintaining proper airflow and reliable thermal protection in gas and electric heating systems.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
