A capacitor's printed ratings are more useful to a supplier than a description such as 'the round AC capacitor'. Have the technician identify the required replacement and supply a readable label photograph. This guide is about ordering information; it does not describe testing, discharging or wiring a capacitor.
Capture the entire label
Include the part reference, capacitance markings, voltage rating and any separate values shown on a dual-run component. Do not crop the photo to one large number. Add the AC unit model and the technician-approved specification, because a label on an old component may not establish that it was the correct component for the equipment.
Confirm the requested configuration
Record the component type, dimensions and mounting arrangement as secondary information. If a proposed alternative differs from the approved reference, ask the technician to assess it before purchase. Avoid treating a larger printed number as an automatic upgrade. Keep the confirmed reference in the maintenance record so future orders do not depend on recollection or an unclear photograph.
A practical enquiry example
A label showing two capacitance values should be photographed in full. Copy both values as written and let the technician approve the specification, rather than sending only whichever number appears larger on the label.
Enquiry checklist
- Complete, readable label photograph
- Equipment model and part reference
- All marked ratings and component type
- Technician approval of the replacement
Can I choose a replacement using its shape?
No. Shape and mounting are secondary checks. The approved ratings and equipment-specific reference control selection.
Discuss your requirement with Refco
Prepare the approved references and quantities, then contact the branch to confirm availability and collection details before visiting.
