Raypak H000333 10k Ohm Thermistor Sensor Kit for Pool & Spa Heaters

The Raypak H000333 is a genuine OEM replacement 10k Ohm thermistor sensor kit designed for use with Raypak pool and spa heaters. The thermistor sensor monitors water temperature and communicates readings to the heater's control board, allowing the system to maintain accurate and consistent water temperatures.

Using a genuine Raypak replacement thermistor ensures proper calibration and compatibility with your heater's electronic control system. A faulty or failed thermistor can cause incorrect temperature readings, nuisance shutdowns, or prevent the heater from firing altogether — making this an essential diagnostic and maintenance part.
