About this sensor

The HydroQuip 36" Hi-Limit Sensor Assembly (5-60-6005) is an essential safety component designed for Gecko SSPA control systems. This OEM replacement sensor features a 36-inch length with a 5/16" bulb diameter, providing reliable overheat protection for your spa. When your control system displays HH, ICE, or OH error codes, this hi-limit sensor is often the solution to restore safe operation.

Built to HydroQuip's exacting standards, this sensor assembly delivers the exact fit and performance your spa requires. Every sensor ships with our 1-year warranty and same-day shipping commitment, ensuring minimal downtime. The 36-inch cable length provides flexibility for various spa configurations while maintaining precise temperature monitoring. Before installation, verify your existing sensor's cable length and bulb diameter to confirm compatibility with this replacement part.

Before you buy — quick checklist

  • Measure your existing sensor cable length — this unit is 36 inches
  • Verify your existing sensor bulb diameter is 5/16"
  • Confirm your control system is a Gecko SSPA or HydroQuip SSPA — this is not a universal fit
  • Check whether the fault code is hi-limit related (HH, OH, ICE) or a separate temp sensor fault before ordering
  • Inspect the sensor well or mounting location for corrosion or blockage that may have caused the original failure

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