Before you buy — quick checklist

  • Confirm your existing thermostat is a Robertshaw C/1-22RX model before ordering
  • Verify the 119°F trip point matches your spa's OEM specification — using the wrong setpoint can cause nuisance shutdowns or unsafe operation
  • Inspect the thermostat well or sensor port for corrosion or damage before installing the new unit
  • Check whether the fault is in the thermostat itself or a related component (heater element, control board) to avoid unnecessary replacement
  • Note the wire terminal configuration on your existing unit to ensure correct reconnection

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