Flow Sensor and Thermistor Repair in Pomona
Tankless heaters use flow sensors to start and thermistors to regulate temperature.

Temperature becomes steady again once readings are correct.

A tankless unit that leaks internally or shows a fault you cannot clear needs prompt attention. We prioritize no-hot-water calls and arrive with common sensors, igniters and filters.
