Fan Not Working? Quick Fixes & When to Call a Pro

Got a fan that just won’t turn on? You’re not alone – a silent extractor or bathroom fan is a common annoyance in many homes. The good news is that most problems are easy to spot and can be solved without tearing down walls. Below you’ll find the most common reasons a fan stops working, a short DIY checklist, and clear signs that it’s time to call a qualified engineer.

Common Reasons Fans Stop Working

First, check the power. A tripped circuit breaker or a blown fuse is the simplest culprit. Flip the breaker back on or replace the fuse and see if the fan revives. If power is fine, the next suspect is the fan motor. Motors can overheat, seize, or lose their bearings after years of grease buildup.

Another frequent issue is a blocked or dirty fan blade. Grease, dust, and even pet hair can jam the blades, stopping rotation. In bathroom fans, moisture can cause corrosion on the motor windings, leading to intermittent operation or a complete shutdown.

Lastly, the switch or wiring may have failed. Light switches, pull‑chains, or wall‑mounted controls can wear out, especially if they’re used daily. Loose wires inside the fan housing can also cause a loss of power, which is harder to see without opening the unit.

DIY Checks Before Calling a Pro

Start with a quick visual inspection. Turn off the fan at the breaker, remove the cover, and look for obvious dirt or broken parts. A soft brush or a vacuum can clear most debris in a few minutes. While the cover is off, give the motor a gentle spin – it should turn freely. Any resistance points to a bearing problem that needs lubrication or replacement.

Next, test the switch. Use a small lamp or a voltage tester on the fan’s wiring. If you get voltage at the motor but the fan still won’t run, the motor is likely dead. If there’s no voltage, the switch or the wiring is at fault. Replace a faulty switch yourself if you’re comfortable working with basic electrical parts, but always double‑check that the power is off.

If you’ve cleared debris, verified power, and the fan still won’t work, it’s time to call a professional. A certified gas engineer can safely test the motor, replace worn bearings, or rewire the unit to meet local safety standards. Trying to force a jammed motor can damage the fan beyond repair.

Regular maintenance saves you from these headaches. Wipe the fan cover every few months, run the fan for a few minutes after a hot shower to dry out moisture, and schedule a yearly check if the fan is part of a larger ventilation system.
