Got a whirring fan that’s gone silent or a bathroom that feels stuffy? Bad ventilation isn’t just annoying, it can cause mould, odors and higher energy bills. The good news? Most fan and vent issues are fixable with a few tools and a little know‑how. Below you’ll find the most common problems, step‑by‑step repair advice, and clear signs you should call a professional.
Before you grab a screwdriver, figure out what’s actually wrong. Here are the top culprits you’ll see around the house:
Identifying the symptom helps you pick the right fix and avoids unnecessary parts purchases.
1. Safety first. Turn off power at the circuit breaker and double‑check the fan is dead with a voltage tester. This protects you and your home.
2. Remove the cover. Most extractor fans have a simple snap‑on or screwed‑on grille. Take it off, then unscrew the fan housing to expose the motor.
3. Clean the motor and blades. Use a soft brush or vacuum to clear dust, grease and cobwebs. A clean motor runs cooler and lasts longer – exactly what our Extractor Fan Motor Cleaning guide recommends.
4. Check the blades. Make sure they spin freely. If they wobble, tighten the mounting bolts or replace a bent blade. A straight blade restores smooth airflow.
5. Inspect wiring. Look for frayed insulation, loose connectors or burnt spots. Tighten any loose screws; if a wire is damaged, replace it with the same gauge copper wire.
6. Test the motor. Re‑connect power temporarily (keep the cover off). If the fan still doesn’t run, the motor likely needs replacement. Motors are inexpensive, but if you’re not comfortable soldering, it’s smarter to let a pro handle it.
7. Re‑assemble and seal. Put the housing back, snap the grille on and restore power. Run the fan for a few minutes to ensure the airflow is back to normal.
Most homeowners can handle cleaning and basic checks in under 30 minutes. If you reach step 6 and the motor is dead, or the fan keeps tripping the breaker, it’s time to call a qualified technician.
Regular maintenance makes a huge difference. A quick motor clean every six months keeps the fan humming, blocks mould growth and saves on energy. Think of it like a car oil change – simple, cheap, and it prevents big breakdowns later.
