Ceiling Fan and Exhaust Fan Repairs

Fans are easy to take for granted until one starts wobbling, humming, or stops working. Ceiling fans help with comfort, and exhaust fans in bathrooms and kitchens help control moisture and odors. Here is how to troubleshoot common problems and when a repair needs a professional.

Ceiling fans: common problems

Wobbling

A wobble is usually caused by unbalanced or loose blades, loose mounting screws, or a bracket that isn't secure. Most wobbles aren't dangerous, but a fan that shakes badly should be checked.

Simple steps:

1. Turn off the fan and switch off its circuit breaker.
2. Tighten the screws that attach blades to the blade holders and the holders to the motor.
3. Check that the canopy and mounting bracket are secure.
4. Use a blade balancing kit, which comes with small weights, if the wobble continues.

Noise

Clicking can come from loose screws or a loose light fixture. Humming can point to a speed control issue, a failing capacitor, or a dimmer switch that isn't rated for fans. Grinding may mean worn motor bearings.

Fan won't turn on or runs on only one speed

Check the wall switch, pull chains, remote batteries, and the breaker first. If those are fine, a failed capacitor, receiver (on remote-controlled fans), or switch is a common cause. A motor failure is less common but possible.

Light kit problems

If the fan runs but the light doesn't, try new bulbs that meet the fixture's wattage limit. Some fixtures have built-in limiters that shut off the light when overloaded.

Exhaust fans: common problems

Bathroom and kitchen exhaust fans run in humid, greasy, or dusty conditions, which shortens their life.

• Weak airflow. Dust and lint build up on the grille and fan blades. A clogged or crushed duct also reduces airflow.
• Loud noise. A rattling grille, loose housing, or worn motor bearings are common causes.
• Fan doesn't run. Check the switch, timer, or humidity sensor, as well as the breaker or GFCI outlet that may be on the same circuit.
• Moisture problems. Fogged mirrors that linger, mildew, or peeling paint can mean the fan isn't moving enough air or isn't vented outside.

Simple maintenance

• Dust ceiling fan blades regularly to reduce imbalance
• Tighten fan screws once or twice a year
• Remove and clean exhaust fan grilles
• Run bathroom fans during showers and for a while afterward
• Check that the exhaust duct vents outdoors, not into an attic

When to call a pro

Turn off power at the breaker before any work. Call an electrician or qualified technician if:

• You need to open the fan housing or work on wiring
• The fan motor is burning out or smells hot
• You see scorch marks or the fan trips the breaker
• The ceiling box isn't rated for a fan
• You want to replace a fan on a high or sloped ceiling
• An exhaust fan needs new ductwork or a new roof or wall vent

Replacing a fan motor is sometimes possible, but on many fans replacing the whole unit makes more sense. A technician can help you compare.

If you replace a bathroom exhaust fan, check that the new one is sized for the room and that the duct runs to the outside. A fan that is too small or vents into the attic can leave moisture behind, which can lead to mold and damage to ceilings and framing over time.

How home warranties usually handle fans

Many home warranty plans cover ceiling fans and exhaust fans as part of their electrical coverage or as a separate item. Coverage generally applies to mechanical and electrical failure from normal use. Common limits include:

• Remote controls, light kits, and bulbs may be excluded
• Cosmetic parts like blades or housings may not be covered
• Duct and venting work may be excluded or limited
• Fans installed improperly may not be covered

Read the contract's ceiling fan and electrical sections carefully. See our ceiling fan coverage page and electrical coverage page for typical inclusions.
