Zodiac R0389600 Honeywell Cad Cell Replacement for Zodiac Jandy XL 3 Oil Fired Pool and Spa Heaters

Check the heater model before ordering

The R0389600 cad cell is listed as a Honeywell replacement for Jandy XL-3 oil-fired heaters, specifically models 2000 and 3000. Match those model numbers to your heater nameplate rather than relying on the term cad cell alone.

• Part match: verify R0389600 or an equivalent part number supplied by your service documentation.
• Fuel type: confirm the heater is oil-fired; do not assume a gas heater uses this component.

Keep the removed component beside the new one before installation to confirm connector orientation and housing shape. Because replacement involves electrical and fuel-connected equipment, have a qualified technician perform installation. Amazon listing.
