Having trouble getting dry after your shower because a broken bathroom fan is failing to do its job? If your bathroom exhaust fan isn’t working or makes squealing and rattling sound, you need to fix faulty wiring, replace the motor, or get a new unit.

Homeowners can troubleshoot a broken bathroom fan themselves. If the problem relates the electrical wiring or you need a replacement fan, you should ask a local electrician to inspect and fix things.

Broken Bathroom Fan Troubleshooting

Broken Bathroom FanFirst, let’s look at the steps to fix a bathroom exhaust fan that A) does not turn on, B) has started making loud noises, or C) does not move air whatsoever:

  • Check the circuit breaker. The bathroom fan might not be on the same circuit as the bathroom lights. Check your panel for any tripped breakers or blown fuses.
  • Use a voltage tester on the switch. This would identify a dead switch that needs replacement. If the wiring looks damaged, don’t just replace the switch yourself—ask an electrician to resolve whatever issue has overheated the wiring.
  • Ask an electrician to replace a broken bathroom fan motor. The motor itself costs relatively little, and an electrician can replace an exhaust fan motor in about an hour.

Bathroom Fan Not Venting Well

What if your broken bathroom fan seemingly turns on just fine, but does not remove steam or humidity?

The problem might still be with the fan motor, especially if the fan sounds louder than it used to. In this case, you need to follow the steps above.

If you are simply dissatisfied with the performance of the fan, you should access the duct area if possible to troubleshoot other issues. Perhaps that broken bathroom fan was actually installed without ductwork that leads anywhere for the steam to escape.

Why You Should Install a Bathroom Fan Timer

Many people make the mistake of running the fan only while they’re using the bathroom and only with the door closed. Ideally, the fan should run for at least ten minutes after a shower or bath with the door open.

If you’re replacing a broken bathroom fan, get a timer switch installed so you can leave the fan running without needing to come back and turn it off.

We often find that a broken bathroom fan has been caused by a rusted motor or moisture damage to the electrical circuit because the fan hasn’t been given time to clear the humidity. An open door helps with air intake so the fan can ventilate and dehumidify more effectively.

Installing a bathroom fan timer is a fast, easy job for a professional electrician. Combine it with a broken bathroom fan replacement, and your new unit will work better and last longer.
