Possible Causes
Worn or cracked keypad overlay, Moisture intrusion, Damaged topside cable, Control pack keypad input fault
How to Fix / Troubleshooting
Safety first: Turn off power before disconnecting the topside panel.
- Inspect overlay: Look for cracks, bubbles, or water under the keypad overlay. Moisture can cause ghost presses.
- Dry the panel: If minor moisture is present, allow the panel to dry completely. Do not use heat guns directly on the panel.
- Check cable: Inspect the topside cable for cuts or pinches and reseat the connector at the control pack.
- Replace topside: If issues persist, replace the Master Spas topside control panel with the correct model for your spa.
- Control pack issue: If a new panel behaves the same, the control pack keypad input circuit may be faulty and require replacement.
