These are general published reference ranges, not a model-specific lookup; always verify against the manufacturer's own documentation. Age and model identity cannot establish safety. Record your own installation or manufacture date, inspection observations, and a replacement-cost range in the ApplianceAgeBook workspace to plan a specific reserve for your unit.
