How to Replace a Bathroom Exhaust Fan Without Professional Help

DIY Guide: Swapping Out Your Bathroom Exhaust Fan with Ease

Your bathroom exhaust fan has one job—keeping moisture and odours at bay. But when it starts wheezing like an old kettle or stops working altogether, it's time for a change. If the thought of tackling this yourself has you feeling nervous, don't worry. Swapping out a bathroom exhaust fan is easier than you think, and you don’t need a tradie to get the job done. Let’s roll up those sleeves and dive in!

What You’ll Need

Before you start, gather your tools and supplies. You don’t want to be halfway through the job, balancing on a ladder, only to realise you’re missing a crucial piece.

• New bathroom exhaust fan (match the size of your old unit)
• Screwdrivers (Phillips and flathead)
• Drill (if needed for new holes)
• Voltage tester
• Duct tape
• Wire connectors
• Ladder
• Pencil and measuring tape

Step 1: Turn Off the Power

Before touching anything, switch off the power at your circuit breaker. You’re working with electrical wiring, so safety is your top priority. Use a voltage tester to ensure no current is running to the fan wires before you proceed.

Step 2: Remove the Old Fan

Most bathroom fans have covers that pop off with a little tug. Once you’ve removed the cover, unscrew the unit from the ceiling. Carefully disconnect the wiring and ductwork. If your new fan is the same size, you can slide it into place using the existing hole. If not, you may need to enlarge the opening.

Step 3: Install the New Fan

Attach the ductwork first. A secure fit is key to proper ventilation. Use duct tape to prevent any air leaks. Next, connect the wiring. Match the corresponding wires—black to black, white to white, and green (or bare copper) to the grounding screw. Use wire connectors for a solid connection.

Step 4: Secure It and Test

Once the wires are connected, push the fan up into the ceiling and screw it into place. Attach the cover, restore power at the circuit breaker, and give it a test run. If it hums to life without any flickering lights or strange noises, you’re all set!

Pro Tips for Longevity

• Clean your fan cover every few months to keep airflow unrestricted.
• Opt for an exhaust fan with a humidity sensor for better moisture control.
• If the fan is noisy, check for loose screws or ductwork that needs tightening.

So there you have it! With just a bit of effort, you can keep your bathroom fresh and mould-free without calling in a professional. Head down to Strathalbyn H Hardware for all the tools and advice you need—we’re happy to help!
