If your extractor fan has suddenly gone quiet, is making a grinding noise, or just won’t turn on at all, you’re not alone. In Auckland homes, extractor fans are one of the most ignored but most essential appliances. They pull out steam, grease, and bad smells from kitchens and bathrooms. When they fail, the problem doesn’t just get annoying-it can lead to mold, damp walls, and even health issues over time. So who do you call when your extractor fan stops working?
Don’t Try to Fix It Yourself Unless You Know What You’re Doing
A lot of people think replacing a fan blade or resetting a circuit breaker is enough. Sometimes it is. But most extractor fan failures aren’t simple. The motor might be burnt out, the capacitor could be dead, or the wiring could be frayed behind the wall. If you’re not comfortable working with electricity-or if you’ve already tried unplugging it and it still doesn’t work-stop. DIY fixes can turn a $200 repair into a $1,200 mess.
Extractor fans in New Zealand homes are usually wired directly into the mains. Even if the switch looks off, the power might still be live behind the unit. One wrong move with a screwdriver and you’re looking at a trip to the hospital, not just a broken fan. That’s why calling a qualified technician isn’t just smart-it’s safer.
What Kind of Technician Do You Need?
You don’t need an electrician for every extractor fan issue, but you do need someone who understands both appliances and electrical safety. Look for a technician who specializes in extractor fan repair, not just general appliance repair. Some handyman services will take the job, but they might not have the right tools or experience to diagnose motor failures, capacitor issues, or duct blockages.
Good extractor fan technicians can:
- Test the motor and capacitor with a multimeter
- Check for blockages in the ducting (common in older homes)
- Replace bearings or fan blades without damaging the housing
- Verify if the issue is the fan itself or the wall switch or timer
- Recommend upgrades if your fan is outdated or undersized
In Auckland, many homes built in the 1980s and 1990s have extractor fans that are now 30+ years old. Those units were often low-power, poorly designed, and never meant to last. A technician who’s seen hundreds of these knows exactly what’s likely to fail-and what’s worth replacing versus repairing.
Signs It’s Time to Call a Pro
Here’s what to watch for:
- No airflow even when the switch is on
- Loud grinding, buzzing, or squealing-not just normal hum
- Intermittent operation-works sometimes, then stops
- Tripping the circuit breaker every time you turn it on
- Visible smoke or burning smell-turn it off immediately and call someone
- Moisture buildup on walls or ceilings after showers or cooking
If you’re seeing two or more of these, it’s not a coincidence. Your fan is failing, and the longer you wait, the more damage it causes. Mold grows fast in Auckland’s damp climate. A single extractor fan failure can lead to $5,000 in wall repairs if left unchecked.
What to Ask Before You Book Someone
Not all service providers are equal. Here’s what to ask before you pay anyone:
- Do you specialize in extractor fans? Not just ‘appliances’-specifically extractor fans.
- Do you carry common replacement parts? Most units use standard motors (like 120mm or 150mm DC motors). If they say they need to order parts and come back, that’s fine-but make sure they know exactly what they need.
- Do you check the ducting too? A new fan won’t help if the duct is clogged with grease or crushed behind the wall.
- What’s your warranty on parts and labor? Reputable technicians offer at least 6 months on repairs. Anything less is a red flag.
- Are you licensed and insured? In New Zealand, anyone working on fixed wiring needs to be registered with an electrical licensing body. Ask for their license number.
Companies that won’t answer these questions clearly? Walk away. You’re paying for expertise, not just a man with a toolbox.
How Much Should You Expect to Pay?
Prices vary based on location, fan type, and complexity. In Auckland, here’s what you’ll typically pay:
| Service | Cost Range | Notes |
|---|---|---|
| Diagnostic visit | $60-$90 | Usually waived if you proceed with repair |
| Capacitor replacement | $120-$180 | Most common fix for silent fans |
| Motor replacement | $220-$350 | Includes labor and new unit |
| Duct cleaning and inspection | $150-$250 | Recommended if fan is old or in kitchen |
| Full unit replacement | $350-$700 | Includes new fan, ducting, and installation |
Replacing the whole unit isn’t always necessary. If your fan is less than 10 years old and the housing is intact, a motor or capacitor swap often saves you hundreds. But if your fan is from the 90s and the casing is cracked, it’s time for a new one. Modern fans are quieter, more efficient, and use 60% less power.
What If You’re Renting?
If you live in a rental property, you’re not responsible for repairs unless you damaged the fan. New Zealand’s Tenancy Act says landlords must keep fixed appliances in good working order. That includes extractor fans.
Don’t try to fix it yourself. Don’t wait until your walls are covered in mold. Send a written request to your landlord or property manager with a clear description: “The extractor fan in the kitchen is not working. It makes no noise when turned on. There is visible condensation on the ceiling after cooking. I request a qualified technician be sent to diagnose and repair or replace the unit.”
Keep a copy. If they ignore you, you can contact Tenancy Services. A broken extractor fan isn’t a minor issue-it’s a health hazard. Landlords are legally required to act.
When to Upgrade Instead of Repair
Here’s the truth: sometimes repair isn’t the best option. If your fan is:
- Over 15 years old
- Not energy rated (no NZ E3 label)
- Extremely noisy even when new
- Installed in a bathroom without a timer or humidity sensor
Then upgrading is smarter than fixing. New extractor fans with humidity sensors turn on automatically when steam rises. They’re quiet, use less power, and last longer. Brands like Zehnder, Vent-Axia, and Extracta offer models that fit standard 150mm ducts and are easy to install.
Some local plumbers and electricians in Auckland now offer bundled services: repair the old unit, then install a new energy-efficient one in the same spot. That’s often cheaper than replacing it twice.
Where to Find a Reliable Technician in Auckland
Word-of-mouth still works best. Ask neighbors, especially if they’ve had the same issue. Local Facebook groups like “Auckland Home Repairs” or “Auckland Renters Support” are full of real recommendations.
Look for technicians who:
- Have a professional website with clear service areas
- List extractor fan repair as a specific service (not buried under “appliances”)
- Have Google reviews with photos of actual repairs
- Offer same-day or next-day service
Avoid companies that only answer with a call center. You want someone who shows up, looks at the unit, and explains what’s wrong in plain English-not jargon.
Final Tip: Don’t Wait for the Worst Case
A broken extractor fan might seem like a small thing. But in Auckland’s humid climate, it’s one of the quietest home disasters waiting to happen. Damp walls don’t just smell bad-they attract mold, weaken timber, and can trigger asthma. Every day you delay is a day your home is at risk.
If your fan’s not working, don’t ignore it. Don’t just turn on the window fan and hope for the best. Call a specialist. Get it fixed. Or get it replaced. Either way, act now. Your walls-and your health-will thank you.
Can I fix my extractor fan myself?
You can try basic checks like cleaning the grille or resetting the circuit breaker, but most failures involve electrical components like capacitors or motors that require testing tools and safety knowledge. If the fan doesn’t respond after unplugging and waiting 10 minutes, stop. DIY repairs can lead to electric shock or fire. Always call a qualified technician for anything beyond surface cleaning.
How long does an extractor fan usually last?
Most extractor fans last between 10 and 15 years, depending on usage. Kitchen fans wear out faster because of grease buildup. Bathroom fans last longer but can fail from moisture damage. If yours is over 15 years old, even if it still works, consider replacing it with a modern, energy-efficient model.
Why is my extractor fan so loud?
Loud noises usually mean worn bearings, a damaged motor, or a blocked duct. Grease and dust buildup inside the fan housing can cause imbalance, leading to rattling or screeching. A technician can clean the blades, replace the bearings, or check for duct collapse. Never ignore loud operation-it’s a sign the motor is under strain and could fail soon.
Does my landlord have to fix my extractor fan if I rent?
Yes. Under New Zealand’s Residential Tenancies Act, landlords must keep fixed appliances like extractor fans in good working order. If it’s broken and causing damp or mold, you have the right to request a repair in writing. If they ignore you, contact Tenancy Services. A non-working extractor fan is a health and safety issue, not a minor inconvenience.
What’s the difference between a ducted and non-ducted extractor fan?
Ducted fans vent air outside through a pipe-this is the only effective type for kitchens and bathrooms. Non-ducted (recirculating) fans just filter air and blow it back into the room. They don’t remove moisture or odors properly and are not recommended for bathrooms or high-moisture areas. If your home has a non-ducted fan, it’s likely outdated or improperly installed. Replace it with a ducted model.
