What usually goes wrong with ceiling fans
Speed problems are frequently caused by a failing capacitor or pull chain switch. Fans controlled by remotes have a receiver in the canopy that can fail, especially in hot attics above. Humming often comes from a standard dimmer being used as a fan speed control — which can damage the motor.
Wobble usually comes from loose mounting or blade imbalance, but a fan on a non-rated box is a safety concern. If a fan is old or the repair costs approach replacement, installing a new fan may make more sense.
What the work typically involves
Identify the symptom
Determine whether the issue is power, control, motor, light kit or mounting.
Check power and controls
Test the circuit, wall switch, remote or receiver.
Repair components
Replace capacitors, switches, receivers or light kit parts as needed.
Secure and balance
Tighten mounting, confirm the box rating and balance the blades.
Common reasons homeowners call
- Fan stuck on high or low
- Remote stopped working
- Fan light works but fan doesn't (or vice versa)
- Wobbling that's getting worse
- Humming at certain speeds
Stop using the fan and call if you notice
- Burning smell from the fan
- Fan housing hot to the touch
- Sparks at the canopy
- Visible sagging or movement of the mount
- Fan slowing down over time
Safety considerations
Turn it off at the breaker. Turn the fan off at the breaker before investigating. Never use a light dimmer to control a fan motor, and stop using any fan that's pulling away from the ceiling.
What an electrician will check
- Box rating and mounting hardware
- Capacitor and switch function
- Remote receiver and wall control
- Wiring connections in the canopy
- Blade balance and motor condition

Frequently asked questions
The most common cause is a failed capacitor or pull chain switch. Both can usually be replaced.
Slight wobble is often a balance issue. Significant or worsening wobble, or a fan on a non-fan-rated box, should be checked promptly.
Humming often comes from an incompatible wall control, a failing capacitor or loose parts. A dimmer used as a speed control is a frequent culprit.
