A visual description such as “outdoor-unit board” is rarely enough. One VRF series may use different revisions by capacity, production date, region or electrical specification. Correct identification begins with the full equipment identity.
Send these six items with every spare-parts request
Clear evidence allows the supplier to check compatibility before quoting. Do not remove or discard the original part until identification is complete.
- Full model number from the unit nameplate
- Serial number and, where shown, production or revision code
- Electrical data and destination market
- Part number printed on the component or PCB label
- Clear photos of the complete part, connectors and labels
- Fault code, symptom and technician’s diagnosis where available
Model number is not always the part number
The unit model identifies the equipment family, while the replaceable component may have its own service part number and revision. A board with similar dimensions or connectors may still be electrically or firmware incompatible.
Ask for a compatibility statement
The quotation should repeat the unit model and the proposed part number, state whether the part is new, superseded or subject to additional checks, and list any related items required for replacement. Safety-critical and refrigerant-circuit work must be handled by qualified personnel.
Plan packing and small-part shipping
Electronic boards require antistatic and moisture protection. Sensors, valves and fragile assemblies need secure internal packing. Agree whether parts will ship alone or with a larger project order and keep the package label linked to the quotation reference.
