About this relay/contactor

Built to Master Spa's exact specifications, this S86 style relay ensures reliable switching of pumps, heaters, and other critical spa components. At Bubbles Supply, we guarantee an exact fit for your spa and offer same-day shipping on in-stock items, backed by our comprehensive 1-year warranty.

Common symptoms this part fixes

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

  • Pump or heater not receiving switching signal

Before you buy — quick checklist

  • Confirm your existing relay is the S86 style and matches the 120V AC coil voltage — not all S86-series relays share the same coil voltage
  • Verify the 20A rating is sufficient for your load — check the amp draw of the component this relay controls
  • Confirm DPDT (Double Pole, Double Throw) configuration matches your circuit — do not substitute SPDT or other configurations
  • Physically inspect and match the terminal layout on your existing relay before removal
  • Check your spa's control board or panel documentation to confirm this exact part number is specified

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