Before you buy — quick checklist

  • Confirm your spa uses a Gecko in.grid control system — check the existing module label for the 0608-521033 part number
  • Verify the error codes you're seeing are HH or OH — other fault codes may indicate a different failed component
  • Check whether the fault is in the control module itself or in a sensor (thermistor/hi-limit sensor) before replacing this unit
  • Document your existing wiring connections or photograph them before removal — this module interfaces with multiple harness connectors
  • Confirm this is an OEM Gecko Alliance part number match for your specific heat pump model before ordering

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