Bathroom Extractor Fan: How to Fix, Replace, and Keep It Working

That annoying damp smell in your bathroom? Chances are your extractor fan has given up. Before you panic and call a pro, check out these practical steps. Most fans just need a quick clean or a simple part swap, and you’ll save time and money.

First, make sure the fan is actually getting power. Flip the bathroom light switch – if the light works but the fan doesn’t, you might have a tripped circuit breaker or a loose wire. Turn the breaker off, remove the fan cover, and look for any obvious loose connections. If everything looks solid, move on to the next check.

Common Problems and Quick Fixes

Fan won’t spin. Dust and grime build up on the motor and blades, causing the motor to stall. Unscrew the cover, pull out the fan, and clean the blades with a soft brush. A can of compressed air can clear out the motor’s vents. Re‑assemble and test – often the fan revives instantly.

Weak airflow. Over time, the fan’s internal filter gets clogged. Many fans have a removable mesh or charcoal filter – wash it with warm, soapy water and let it dry completely before reinstalling. If the fan still feels sluggish, the motor bearings may be worn out; replacing the motor is usually cheaper than a whole new unit.

Noise or rattling. Loose screws or a warped housing can cause vibrations. Tighten all mounting screws and check that the fan sits level in the ceiling. If the housing is cracked, a replacement fan is the best option.

When to Replace Your Bathroom Extractor Fan

If you’ve tried cleaning, resetting the breaker, and tightening screws but the fan still fails, it’s time to consider a new unit. Look for these signs:

• Age: most fans last 8‑12 years. Older models may lack energy‑saving features.
• Persistent motor humming with no airflow – the motor is probably burnt out.
• Excessive moisture damage to wiring or housing.

Replacing a fan isn’t rocket science, but you must follow safety rules. Turn off the main power at the consumer unit, and if the wiring feels beyond your comfort zone, call a qualified electrician. For most homeowners, the DIY route works for replacing the fan housing and motor, especially with a plug‑in model that doesn’t require hard‑wired connections.

Maintenance is the secret to a long‑lasting fan. Every six months, give the blades a quick wipe and replace or wash the filter. A yearly check of the motor’s vent will keep it from overheating. These tiny chores add up to years of reliable performance and lower energy bills.

So, next time your bathroom feels muggy, you’ll know exactly what to do – clean, troubleshoot, or replace. A well‑maintained extractor fan not only removes moisture but also helps prevent mold, keeping your bathroom fresh and healthy.
