Quick answer
Ceiling fans fail from a burnt-out capacitor, a broken pull-cord switch inside the housing, or a failed wall controller. The capacitor is the usual answer, and it has a recognisable symptom: the fan hums but will not start, or starts only if you spin a blade by hand, or runs at one speed only. It is an inexpensive part and a short job.
Common causes
- Failed start capacitor — hums but will not start, or runs slowly
- Broken pull-cord switch inside the fan housing
- Wall controller or fan speed regulator failure
- Loose connection at the ceiling rose or in the fan canopy
- Seized motor bearings on an older fan
- Tripped breaker or a lighting circuit fault feeding the fan
What you can do now
- 1Check the breaker and the wall switch first
- 2Note the symptom precisely — humming without turning, one speed only, or completely dead
- 3Try the pull cord as well as the wall control, since either can fail independently
- 4Listen for bearing noise, which indicates the motor rather than the capacitor
- 5Do not spin the blades to start it as a routine workaround; that confirms a fault, it does not fix it
When to call a professional
Use an electrician who carries ceiling-fan capacitors and switches, since the diagnosis and the repair then happen in one visit. Call rather than leaving it, because a fan that hums without turning is drawing current through a stalled motor. If the bearings have seized, replacement is usually more sensible than repair.
