  • Locate your control pack model number (typically printed on a label on the pack housing) and cross-reference with HydroQuip documentation
  • Inspect the thermostat shaft on your control pack — verify the shaft is undamaged and the knob is the only failed component
  • Check whether the D-shaft or spline profile on your existing thermostat matches this knob's bore before ordering
