Description
The Noritz NPH028 is a genuine OEM CB Flame Detector Sensor designed to maintain safe and accurate flame monitoring in compatible Noritz tankless water heating systems. As a critical safety component, the flame detector sensor continuously monitors burner operation and signals the control board to shut down the unit if a flame is not detected — helping prevent unsafe operating conditions and protecting both the appliance and its users.
Key Features

Why Replace Your Flame Detector Sensor?
A faulty or degraded flame detector sensor can cause nuisance shutdowns, error codes, or — more critically — allow the system to operate without a confirmed flame signal. Replacing a worn sensor with a genuine Noritz part restores proper safety interlocking and ensures your tankless water heater performs as designed.
Compatibility
