Ceiling fan won't spin

Symptoms

• Fan makes a humming sound but blades don't move
• Fan does absolutely nothing when turned on
• Blades can be spun by hand but don't start on their own

Likely causes

• CommonA failed run capacitorThe capacitor gives the motor its initial push to start spinning; when it fails, the motor may just hum.
• CommonA worn-out motor bearingOld fans can develop enough friction in the motor bearings to prevent starting under normal power.
• PossibleA stuck or broken pull chain switchInternal switches for speed control can fail and cut power to the motor.
• PossibleNo power reaching the fan at allA tripped breaker or failed wall switch can leave the fan completely dead.
• Less commonBlades obstructed or blockedSomething physically blocking the blades, though rare, would also prevent spinning.

What to do

1. Check that the wall switch and any remote are actually sending power, and check the breaker panel.
2. If the fan hums but doesn't spin, try giving a blade a gentle push by hand while it's on to see if it starts moving.
3. If a push gets it going, the capacitor is a likely cause and should be replaced.
4. Turn off power to the fan and check for visible obstructions around the blades.
5. Remove the canopy cover to check the pull chain switch for damage if speeds don't respond correctly.
6. Replace the capacitor with the exact rating specified for your fan model if that's the identified issue.
7. Consider replacing the whole fan if the motor bearings are worn, since motor replacement often costs close to a new fan.

Tools and parts

• Screwdriver
• Step ladder

When to call a pro

Call an electrician or fan repair technician if you're not comfortable replacing a capacitor or switch, or if the motor itself seems to be the issue.
