Description

A Navien 30012033B flow sensor for NCB E-series appliances. The flow sensor is how a combi knows domestic hot water is being drawn, and how much — it is the signal that starts the burner on a hot water call and lets the unit modulate to hold temperature as the draw changes. A failing sensor typically shows as hot water that does not come on, or that swings in temperature. An OEM part, matched to the appliance series.
