Description
Lochinvar & A.O. Smith 100113144 Blower Prover Switch
The Lochinvar & A.O. Smith 100113144 Blower Prover Switch is a genuine OEM replacement safety component designed to confirm proper blower/inducer motor operation before allowing burner ignition. By verifying adequate airflow and draft pressure, this switch plays a critical role in protecting the appliance and its users from unsafe combustion conditions.
Product Overview
The blower prover switch monitors the pressure differential generated by the draft inducer blower. If the required pressure is not achieved — indicating a blocked flue, failed motor, or restricted vent — the switch prevents the ignition sequence from proceeding. This safeguard helps ensure safe, efficient, and code-compliant operation of Lochinvar and A.O. Smith water heaters and boilers.
