Bathroom Fan Not Working? Get It Running Again Fast

If your bathroom fan is silent or just whirring without pulling air, you’re probably annoyed by the extra moisture and smells. The good news is most problems are easy to spot and fix. Below are the steps you can try before you call a professional, plus the signs that it’s time for an expert.

Quick DIY Checks

1. Power check – First, make sure the fan actually has electricity. Switch the light in the bathroom on and off. If the light works but the fan doesn’t, the fan’s wiring or switch may be the culprit. Try resetting the circuit breaker for the bathroom; a tripped breaker is a common cause.

2. Switch test – Bathroom fans usually share a wall switch with the light. The switch can wear out, especially in damp environments. Swap the fan’s switch with another working switch (or use a temporary jumper wire) to see if the fan powers up. If it does, replace the faulty switch.

3. Clean the grille and motor – A layer of dust or bathroom grime can block airflow and cause the motor to overheat and stop. Turn off the power, remove the grille, and vacuum any debris. If you feel comfortable, unscrew the motor housing and wipe the blades with a damp cloth. Re‑assemble and test.

4. Inspect the fan’s wiring – Look for loose connections, burnt spots, or frayed wires inside the fan housing. Tighten any loose terminals and replace any damaged wires. If you see blackening or a burnt smell, stop and call a pro – that’s a sign of an electrical fault.

5. Check the fan’s capacitor – Many fans use a start capacitor to get the motor moving. A bad capacitor can make the fan hum but not spin. If you have a multimeter, test the capacitor for the correct voltage. Replacing a capacitor is inexpensive and usually a quick fix.

When to Call a Pro

If you’ve run through the checks above and the fan still won’t work, it’s time to get professional help. A licensed technician can safely diagnose motor failure, replace worn bearings, or rewire the fan to meet UK regulations. You’ll also avoid voiding any warranties by attempting advanced repairs yourself.

Another red flag is a fan that makes a loud grinding or squealing noise before stopping. That often means the motor bearings are shot and need replacement – a job that requires special tools and expertise.

Finally, if the fan is over 10‑12 years old, the cost of a full motor replacement may approach the price of a new, more efficient unit. A pro can advise whether repair or replacement makes more sense for your budget.
