- Non-returnable — special order. Circuit boards are non-returnable and cannot be canceled once ordered. Cal Spas offers a limited 30-day warranty on their circuit boards.
- Identify by chip number and Balboa 5-digit board number. Look for chip label CS5300R1B (or any revision ending in a different letter, e.g., R1A through R1D) on your existing board. Also confirm the 5-digit number starting with “5” on the white sticker.
- Compatible with Balboa Sensor Assembly 30337. Confirm your existing sensor matches before ordering.
- Do not order by spa model alone. Many Cal Spas models used different board variants. Your chip number and board number are the only reliable identifiers.
