About this pressure switch

The MSPA?TSPA 14" Pressure Switch Harness 9920-400124 is a genuine Gecko Alliance replacement harness designed for spas equipped with Gecko control systems. This OEM 2-wire harness features a 3-pin plug connection and measures 14 inches in length, providing the essential electrical link between your spa's pressure switch and control board.

Built to Gecko's exacting specifications, this pressure switch harness ensures reliable communication for proper pump and filtration operation. At Bubbles Supply, we guarantee an exact fit with our genuine OEM parts, backed by our 1-year warranty and same-day shipping on in-stock items. When replacing your pressure switch harness, always disconnect power at the breaker and verify all connections match your existing wiring configuration before operation.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Pump fails to start despite adequate water pressure
  • Control board throws pressure fault or flow error
  • Spa shuts down intermittently with pressure-related fault codes
  • Pressure switch signal not reaching control board
  • Filteration cycle not initiating correctly

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your spa uses a Gecko Alliance control system (check the control board label)
  • Verify your existing harness is 14 inches in length — measure from connector end to end before ordering
  • Confirm the pressure switch connector is 3-pin — count the pins on your existing plug
  • Inspect the harness for damage (fraying, melted insulation, corroded pins) to confirm the harness — not the switch or board — is the failed component
  • Check that your pressure switch uses a 2-wire configuration compatible with this harness

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
