Step-by-Step Instructions
Turn off power at the breaker
5 minutes
Go to your electrical panel and turn OFF the breaker for the ceiling fixture. Use a voltage tester at the fixture to confirm power is completely off.
Warning
NEVER work on electrical wiring with power on. Always verify with a voltage tester, not just the light switch.
Remove existing fixture
15 minutes
Take down the old light fixture or fan. Remove any glass shades first, then unscrew the mounting screws. Lower the fixture carefully and note how the wires are connected before disconnecting.
Pro Tip
Take a photo of the wire connections before disconnecting anything.
Check the electrical box
5 minutes
The electrical box MUST be fan-rated (metal, rated for 50+ lbs, attached to framing). A standard light box cannot support fan weight and vibration. Look for a label or stamp indicating it's fan-rated.
Warning
Using a non-fan-rated box is a fire and fall hazard. If the box isn't fan-rated, it MUST be replaced.
Assemble fan components
20-30 minutes
Follow manufacturer instructions to assemble the motor housing, downrod, and canopy. Do NOT attach blades yet - they're installed after the fan is mounted.

5 minutes
Attach the fan's mounting bracket to the electrical box using the provided screws. Ensure it's secure - this bracket holds the entire fan.
Hang the motor temporarily
5 minutes
Most fans have a hook or ball mount that lets you hang the motor while connecting wires. Lift the motor and engage this support mechanism so you can work hands-free.
Pro Tip
Having a helper is very useful for this step.
Connect the wires
10-15 minutes
Connect matching colors: black to black (hot), white to white (neutral), green or bare to green or bare (ground). If there's a blue wire, that's for a light kit - connect to black if using one switch, or to a separate hot wire for two switches.
Warning
Double-check all connections are secure and no bare wire is exposed outside wire nuts.
Secure motor to mounting bracket
5 minutes
Lift the fan off the support hook and align it with the mounting bracket. Tighten the canopy screws to secure the fan to the ceiling.
Attach fan blades
15-20 minutes
Attach each blade to its blade arm (usually 4-5 blades). Then attach each blade arm to the motor using the provided screws. Ensure all screws are tight.
Install light kit if applicable
10 minutes
If your fan has a light kit, connect the blue wire from the fan to the light kit wires. Attach the light housing to the fan's bottom cap. Install bulbs and light covers.
Restore power and test
5 minutes
Turn power back on at the breaker. Test all fan speeds and light (if applicable). Check for wobble - some is normal, excessive wobble may need blade balancing.
Pro Tip
If the fan wobbles excessively, try a fan balancing kit (available at hardware stores).
Common Mistakes to Avoid
- Not verifying power is off with a voltage tester
- Using a non-fan-rated electrical box
- Mixing up wire connections
- Not securing blade screws tightly (causes wobble)
- Installing blades before mounting the motor
Safety Warnings
- ALWAYS verify power is off with a voltage tester
- A fan-rated electrical box is NOT optional - standard boxes cannot support fan weight
- If wiring is aluminum, consult an electrician
When to Call a Professional
If there's no existing ceiling box, if you need new wiring run, if the wiring is aluminum (older homes), or if you have vaulted or very high ceilings.
