Heat Exchanger, Coil & Radiator Manufacturing calculator

Warranty Exposure Calculator

Use this calculator to rank warranty exposure on a common scale. It helps quality, engineering, and service teams compare leak, corrosion, vibration, performance, packaging, and installation risks before choosing corrective actions.

What this calculator does

  • Score warranty exposure for heat exchangers, coils, radiators, condensers, evaporators, and oil coolers using severity, occurrence, and detection ratings.
  • Use it when leak risk, corrosion, vibration fatigue, fin damage, pressure failures, gasket issues, or field returns need to be ranked before corrective action.
  • Creates a weighted warranty exposure score from severity, occurrence, and detection risk for thermal product field failures.

Formula used

  • Warranty exposure score = field failure severity × 0.40 + expected warranty occurrence × 0.35 + pre-shipment detection risk × 0.25

Inputs explained

  • Field failure severity: undefined
  • Expected warranty occurrence: undefined
  • Pre-shipment detection risk: undefined

How to use the result

  • Use it for warranty reviews, FMEA updates, corrective action ranking, supplier quality reviews, and launch containment decisions.
  • It is a ranking tool, not a financial reserve model. Use field data, claim rates, service cost, and contract terms for warranty accruals.

Common questions

  • What warranty issues fit this calculator? Use it for leaks, corrosion, vibration cracks, blocked passages, thermal underperformance, pressure failures, port damage, packaging damage, and installation-sensitive failures.
  • What does detection risk mean? It reflects how likely the current manufacturing and test process is to miss the issue before shipment. Higher detection risk means weaker detection.
  • How should teams act on the score? Use it to rank which risks need engineering changes, process controls, supplier action, added testing, or field monitoring first.
  • Can this predict warranty dollars? No. It ranks exposure. Warranty dollars need shipment volume, claim probability, replacement cost, labor cost, freight, and contract terms.
