Fans in the kitchen, bathroom or laundry can stop working out of the blue. It’s frustrating, but most problems are fixable without calling a pro. Below are the most common signs, what they usually mean, and a step‑by‑step guide you can follow right now.
Fan doesn’t turn on at all. The first thing to check is power. Is the switch on? Is the circuit breaker tripped? If the fan has a separate fuse, make sure it isn’t blown. Sometimes the wall switch is the culprit, especially if it’s a dimmer that isn’t rated for fans.
Fan runs but makes a loud humming or rattling noise. This usually means something is hitting the blades or the motor bearings are worn. Dust and debris can also cause vibration. Turning the fan off, cleaning the grille, and tightening any loose screws often solves the noise.
Fan spins slowly or stalls. A motor that’s overheating or a capacitor that’s gone bad will cause low speed. You might feel the fan wobble or notice the motor getting hot. Replacing the capacitor is inexpensive and can restore full speed.
Fan works for a minute then stops. Overheating protection can shut the motor down if airflow is blocked. Check for clogged vents, a dirty filter, or an obstruction behind the fan housing.
1. Turn off the power. Flip the breaker or pull the fuse for safety. Even if the fan is unplugged, you don’t want any surprise shocks.
2. Remove the cover. Most extractor fans have a snap‑on or screw‑on grille. Use a screwdriver if needed and keep the screws in a small bowl.
3. Inspect and clean. Take a dry cloth and wipe away dust from the blades, motor housing, and vent duct. A vacuum with a brush attachment works well for stubborn grime.
4. Check the wiring. Look for loose connections, burnt spots, or cracked insulation. Tighten any loose terminals and replace any damaged wires.
5. Test the capacitor. If the fan is slow or humming, the capacitor is likely the issue. You’ll need a multimeter set to capacitance. Compare the reading to the value printed on the part. If it’s off, replace it—just snap the old one out and snap the new one in.
6. Re‑assemble and restore power. Put the cover back, screw everything in place, and turn the breaker on. Run the fan for a minute to make sure it stays on and is quiet.
If the fan still won’t work after these steps, the motor itself may be burnt out. Motors are generally cheaper to replace than to repair, so buying a new fan unit or a motor kit is often the most sensible move.
Remember, regular maintenance—cleaning the filter every few months and checking for dust buildup—will keep most fans humming along for years. A quick visual check each season can catch problems before they become expensive repairs.
