Zodiac R0023000 150 Degree F Hi Limit Switch Disc Replacement Kit for Select Jandy Pool and Spa Heaters

Verify the disc type and trip temperature

This listing identifies R0023000 as a hi-limit switch disc replacement kit rated for a 150 degree Fahrenheit temperature. The listed fit includes Legacy LRZE, LRZM and Lite2 LD, LG, LJ models, plus LX/LT Low Nox spa heaters in the sizes shown by the product data.

The listed temperature value is a specification to match against the original component; do not treat it as a field-adjustable setting.

• Match your heater nameplate to one of those documented families; do not treat every Jandy heater as compatible just because it uses a hi-limit switch.
• Distinguish this disc from an electronic temperature control assembly, transformer with harness, header plug, or ignition control; those are separate replacement components.
• Check the old part number against R0023000 before ordering; similar-looking safety parts are not interchangeable by appearance alone.
