Description
This is an Genuine OEM Lochinvar Air Pressure Switch used in EnergyRite (model ERN/ERL) pool & spa heaters, which monitors combustion airflow and ensures the inducer fan generates enough static pressure before the heater is allowed to ignite. The Air Pressure Switch acts as a safety interlock that verifies proper airflow before allowing the pool heater to ignite. It ensures that dangerous exhaust gases are being safely vented and that there is enough fresh air for clean combustion.
