🔧 Core Identity & Function

Part Number: 60011‑4 Component: Blower Proof Switch Assembly OEM: AERCO

This assembly is a critical combustion‑safety interlock. It verifies that the blower (combustion air fan) is producing adequate airflow before the burner is allowed to ignite. If airflow is insufficient, the switch prevents ignition, protecting the boiler, the facility, and occupants.

Key functions (confirmed):

• Provides blower/fan proof‑of‑airflow before ignition

• Prevents burner firing when airflow is inadequate

• Ensures safe operation in commercial boiler environments

• Direct OEM drop‑in replacement — no modifications required

Used in:

• AERCO commercial boilers

• AERCO commercial water heaters

• Any system requiring blower‑proof safety interlock in the ignition sequence

Typical replacement scenarios:

• Ignition lockouts due to airflow faults

• Blower proving failures

• Preventive maintenance on combustion‑air systems
