Two numbers find a replacement part: the model number of the appliance or unit, and the part number printed on the old part. Either one works on PartFind. They answer different questions.
Model number: what fits my unit?
The model number is on the appliance or equipment label (where to find it). Search it and you see every part in our fit data for that model, grouped by part type. Use it when you know what is broken but not the exact part.
Part number: what replaces this part?
The part number is stamped or printed on the old part itself, often on a sticker or molded into the plastic. Search it and you go straight to the part, or to the part listed as its replacement. Use it when you have the old part in your hand.
Why a search can show a different number
Makers change part numbers over time. An old number is often replaced, or superseded, by a later one listed for the same units. Each part page lists the numbers it replaces, so an older number still finds the current part. How superseded numbers work.
Which one to use
- You have the old part: search the part number, then check the fit list against your model number.
- You only know the symptom: search the model number and browse the part types.
- You buy for many units: put model and part numbers in one list and request a quote.
Specs matter for HVAC parts
Many HVAC parts, like run capacitors, contactors and transformers, are matched by their ratings rather than by one model number. Match the numbers printed on the old part: microfarads and volts for a capacitor, coil voltage and amps for a contactor, VA and volts for a transformer.
