About this seal/gasket

**Genuine Hot Spring Spas thermostat with O-ring (part #79006) designed to restore accurate temperature control in your spa.** This OEM control thermistor monitors water temperature and communicates with your spa's control system to maintain your desired heat settings. When thermostats fail, you'll experience temperature fluctuations, error codes like HH, ICE, or OH, or complete heating system shutdown.

**Built to Hot Spring's exact specifications, this replacement sensor includes the necessary O-ring seal for proper installation.** Our exact fit guarantee ensures seamless compatibility with your spa's existing wiring harness and mounting configuration. Ships same day from our Canadian warehouse and backed by our comprehensive 1-year warranty for complete peace of mind. Professional installation recommended to ensure proper sensor placement and waterproof seal integrity.

Common symptoms this part fixes

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

  • HH error code displayed on topside control

  • Heating system shutting down unexpectedly
  • Spa reads incorrect water temperature on display

Before you buy — quick checklist

  • Confirm your spa displays HH, ICE, or OH error codes before replacing — these are the primary indicators of thermistor failure
  • Verify your Hot Spring spa model to ensure part #79006 is the correct thermistor for your specific control system
  • Check that the existing sensor mounting port and wiring connector style match this OEM unit before ordering
  • Inspect the sensor well or port for corrosion or debris that may need to be addressed during installation
  • Have a multimeter available to test the old thermistor resistance before assuming it has failed — a known-good reading can rule out a control board issue

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