That annoying hum, a fan that won’t spin, or a musty smell drifting from the bathroom? Before you call a pro, think about whether a simple fix will do or if it’s time for a new fan. We’ll walk through the clues, the costs, and the DIY bits so you can decide fast.
First, check the power. Is the fan dead or just quiet? Flip the circuit breaker back on, then test the switch. If there’s no buzz, the motor might be burnt out – a common, cheap fix. You can buy a replacement motor for under £30 and swap it yourself with a screwdriver and a few minutes of effort.
Next, look at the fan blades. Loose or cracked blades cause wobble and noise. Tightening the screws or replacing a broken blade usually costs less than £10. If the fan is still sluggish after cleaning the blades and clearing dust from the vent, the bearings are likely worn. Bearing kits are inexpensive and swap in under an hour.
Watch the vent itself. A blocked vent can make the fan seem dead, but a quick clean‑out with a brush or vacuum restores flow. If the fan works after cleaning, you’ve saved a repair bill altogether.
Age is a big factor. Most extractor fans last 8‑12 years. If yours is older, corrosion and wiring fatigue become a safety issue. Re‑wiring an old fan to meet current standards can cost as much as a brand‑new unit, so swapping is smarter.
Noise levels matter too. Modern fans are whisper‑quiet, while older models can be a constant roar. If you’ve tried motor and blade fixes but the fan is still loud, a new low‑decibel model will give you peace and better airflow.
Finally, consider the layout. If your fan is oddly sized for the bathroom or the vent duct is too small, you’ll never get proper extraction. A new fan with the right CFM rating (cubic feet per minute) will improve moisture removal and prevent mold. Installation costs are about £80‑£120 if you hire an electrician, but the long‑term benefit outweighs a patch‑up that still under‑performs.
Bottom line: If the problem is a dead motor, loose blades, or a clogged vent, repair is cheap and quick. If the fan is old, noisy, undersized, or has wiring issues, replace it. Either way, always turn off the breaker before you start and double‑check that the fan is securely mounted.
Got a stubborn fan? Grab a screwdriver, check the power, clean the vent, and you might save a few quid. When in doubt, a brief call to a local Northampton repair service can confirm whether a repair or replacement is the smarter move – and they’ll be on hand if you need a professional finish.
