About this cord/connector

The 3 Position Jumper Pin 39193 is an OEM replacement part designed for Hot Spring Spas heater relay boards. This essential electrical component controls heater operation by setting the proper relay configuration on your spa's control system. When your spa displays HH (high heat) or OH (overheat) error codes, this jumper pin often provides the fix by restoring proper heater board communication.

As an authentic Watkins Manufacturing part, this jumper pin delivers the exact fit your Hot Spring spa demands. We guarantee precise compatibility and back every part with our comprehensive 1-year warranty. Your replacement ships the same day you order, getting your spa back to perfect operation fast. Ensure your spa's power is completely disconnected before installing this jumper pin on the heater relay board.

Before you buy — quick checklist

  • Confirm your spa displays an HH or OH error code before replacing — these are the primary indicators this jumper is the fix
  • Locate your existing heater relay board and verify the jumper pin is missing, damaged, or seated incorrectly
  • Match the 3-position configuration — do not substitute a 2-position jumper
  • Verify your spa is a Hot Spring / Watkins Manufacturing brand unit — this is an OEM-specific component
  • Disconnect all power to the spa at the breaker before inspecting or removing the board

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