Quality Control Checklist for Ceiling Fans From Bangladesh

If you import ceiling fans, this ceiling fans quality control checklist gives you a practical way to check a shipment before it leaves Bangladesh. A ceiling fan is judged in use: wobble, motor noise or a regulator fault shows at once. Use an agreed sampling plan rather than pieces the factory selects. ISO 2859-1 specifies an acceptance sampling system for inspection by attributes, indexed in terms of the acceptance quality limit (AQL), applicable to end items.¹

Why this checklist matters

Ceiling fans concentrate risk in a rotating electrical product fixed above head height: sweep and balance decide whether the fan runs true, the downrod and mounting parts decide whether it stays secure, and the motor, wiring and regulator decide whether it runs safely at every speed. A fault hidden in the carton, such as a bent blade iron, shows only after installation.

A written checklist removes interpretation. Each point is checked against the approved sample, the specification and the packing list, and recorded as pass, fail or not applicable. Set acceptance numbers per defect class in the purchase order.¹ See the AQL acceptance quality limit explainer.

Before you start

Do not begin until the references are complete: an approved sample per model, sweep and finish, the purchase order and specification with rated voltage, frequency and power, blade sweep, downrod length and tolerances, the regulator type, and the packing specification. Agree the sampling plan in advance,¹ and draw the sample randomly across models, finishes and cartons.

Confirm the safety references before bulk marking is printed. IEC 60335-2-80:2024 deals with the safety of electric fans for household and similar purposes, with a rated voltage of not more than 250 V for single-phase appliances and 480 V for other appliances, and ceiling fans are listed among the fan types it covers.² IEC 60335-2-80:2024 is used in conjunction with IEC 60335-1:2020.² IEC 60335-1:2020 deals with the safety of electrical appliances for household and similar purposes, with the same rated voltage limits.³

The full checklist (numbered, printable)

Dimensions, sweep and components

1. Confirm each sampled carton contains the motor unit, blades, blade irons, downrod, canopy, regulator or remote control and fixing kit named in the specification.

2. Measure blade sweep tip to tip on each sampled fan, assembled as directed, against the specification figure and tolerance.

3. Measure downrod length, canopy size and blade length and width, recording actual values, not pass marks alone.

4. Check blade count, shape and finish on every sampled fan against the approved sample, with no substitution in bulk.

5. Weigh sampled fans where the specification gives a weight, and check each blade for symmetry of shape and pitch.

Blades, balance and mounting

6. Check each blade for cracks, warping, dents, sharp edges and coating damage, on the face, back and edges.

7. Check blade irons for straightness and angle, and confirm every blade screw seats firmly without stripping.

8. Check the downrod, hanger ball and coupling: setscrew tight, safety pin named in the instructions present, and no play when the fan is moved by hand.

9. Check canopy and mounting bracket parts in the kit against the instruction drawing, including screws, washers and insulating parts.

10. Run each sampled fan at every speed and check for wobble at the blade tips, rocking at the canopy and contact between moving and fixed parts, recording the speed where wobble appears.

Motor, wiring and electrical safety

11. Check the rating label on each sampled motor against the purchase order: model, rated voltage, frequency and rated power input must match the order and the carton marking.

12. Check supply leads, terminals and connectors for damage, loose strands and secure fixing, with no copper showing outside a terminal.

13. Check earthing, where the design provides it, is connected as drawn, and that protection symbols on the sample appear the same way in bulk.

14. Run each sampled fan through start, every speed step and stop, checking for failure to start, stalling at low speed, heating smell and sparking.

15. Check motor noise while running: listen for grinding, scraping and bearing rumble separate from normal air movement, at each speed.

16. Confirm safety test evidence where the order requires it names this model and lot. IEC 60335-2-80:2024 also applies to separate controls supplied with fans.²

Regulator and controls

17. Check the regulator or remote supplied with each sampled fan matches the specification, with the correct number of speed steps.

18. Operate every speed step in order and confirm changes in the right sequence, with no dead step or sticking control.

19. Where a remote is supplied, check pairing, range, battery fit and that the fan responds only to its paired control.

20. Check any light kit, timer or reverse function named in the specification works as the manual describes.

Performance evidence: air delivery and noise

21. Review air delivery evidence where the order requires it and confirm the report names this model, sweep and lot. IEC 60879:2019 specifies the performance-measuring methods of comfort fans and regulators, with a rated voltage of not more than 250 V for single-phase fans and 480 V for other fans, and a rated power input of less than 125 W.⁴

22. Confirm the performance report uses the ceiling fan method. Under IEC 60879:2019, comfort fans are classified into two groups for testing, and ceiling fans form one group.⁴

23. Review regulator performance evidence where required, because IEC 60879:2019 covers regulators together with the fan where applicable.⁴

24. Review noise evidence where required. IEC 60704-2-7:2020 applies to electrical fans for household and similar use, including ceiling fans, and treats the motor, impeller and housing, if any, as a single unit.⁵

25. Check by ear that no run fan is clearly louder than the approved sample at the same speed, and hold louder units for review.

Finish, appearance and markings

26. Check coated parts for peeling, bubbles, rust spots and color difference between blades, motor cover and canopy, against the sample under the same light.

27. Check decorative trim and model badges named in the specification for straight placement, secure fixing and correct wording.

28. Check rating markings are legible, durable to a rub by hand and identical across the sample, including voltage, frequency, power and model identification.

29. Check warning and installation wording on the product and in the manual against the approved artwork, with no missing page.

30. Check the manual in each sampled carton: language, model name, wiring diagram, parts list and fixing steps must match this model and destination market.

Packing and cartons

31. Confirm each fan is packed as directed, with blades, irons and motor protected so metal parts cannot rub in transit, with spacers where specified.

32. Check that the fixing kit, regulator or remote, manual and warranty card named in the pack are present in each sampled carton.

33. Check that barcode, model and sweep stickers scan and match the purchase order, and that carton markings match the fans inside.

34. Handle sampled cartons as the carrier would: no crushed corner reaching the product, no split seam and no loose contents.

35. Weigh and measure sample cartons, and check markings and carton count against the packing list.

36. Record every failure by fan, carton and defect type, photograph it, and keep the unit aside until disposition is agreed.

Common failures and how to fix them

The most frequent failure is wobble at high speed, usually because one blade is warped, one blade iron is bent, or blade screws were tightened unevenly. Stop, measure blade height and sweep on the assembled fan, replace the affected blade or iron, and re-run the fan at every speed before more fans are packed. Next is a fan that hums or runs hot at low speed, which points to the regulator or capacitor match for that motor: hold those units, compare the regulator type against the specification, and test a corrected unit before the line restarts.

Loose movement at the canopy traces to a slack setscrew or a missing safety pin in the downrod coupling: refit the coupling as drawn and re-check the affected group. Finish differences between blades and motor cover point to mixed finish batches: re-sort complete fan sets by finish before packing. Crushed cartons point to weak packing for a heavy motor unit: repack as specified and re-check handling on a fresh sample.

Above the agreed acceptance level, options are re-inspection after sorting or rework, documented partial acceptance, or rejection. See the pre-shipment inspection guide.
