Fan Motor Replacement: When & How to Fix Your Kitchen or Bathroom Fan

Ever notice your extractor fan humming weakly or not spinning at all? That’s usually a motor problem. A busted fan motor can make your kitchen smoke-filled or your bathroom steamy, and fixing it is easier than you think if you know the signs.

How to Know It’s Time for a New Motor

First, listen. A motor that whines, rattles, or makes a high‑pitched squeal is on its way out. Second, watch the fan blades. If they wobble, stop moving, or move just a fraction of the normal speed, the motor is losing strength.

Third, check the power. A fan that suddenly stops while the switch is on often points to a burnt‑out motor or a blown fuse. Finally, feel the heat. An overheating motor will feel hot to the touch after a few minutes of use.

When any of these symptoms show up, don’t ignore them. Running a weak motor longer can damage the fan housing, wiring, or even cause a fire hazard.

DIY vs Professional Replacement

If you’re comfortable with basic tools, swapping a fan motor can be a weekend project. You’ll need a screwdriver set, a needle‑nose pliers, and possibly a multimeter to test the wiring. The steps are simple:

  1. Turn off the electricity at the breaker. Safety first.
  2. Remove the fan cover – usually a few screws or clips.
  3. Disconnect the motor wires. Take a photo first so you can reconnect them correctly.
  4. Unscrew the old motor and pull it out.
  5. Slot the new motor in, tighten the screws, and reconnect the wires.
  6. Replace the cover, restore power, and test the fan.

Most homeowners finish this in under an hour. The cost of a replacement motor ranges from £30 to £80, depending on the brand and size. Add a few pounds for screws or a connector if needed.

If the fan still won’t work after a new motor, the problem might be the wiring, the control switch, or a blocked vent. That’s where a professional comes in. A qualified technician from Northampton Appliance Repairs can diagnose hidden issues, ensure everything is up to code, and give you a warranty on the work.

Calling a pro usually costs £70‑£120 for labor plus the price of the part. It sounds higher, but you avoid mis‑wiring, accidental damage, or safety risks. Plus, a local expert knows the common fan models in Northampton homes and can source the right part fast.

Bottom line: If the motor problem is obvious and you’ve got the basic tools, give the DIY route a try. Otherwise, book a local repair service to keep your fan running safely and efficiently.
