How Long Do Kitchen Extractor Fans Last? Lifespan, Maintenance, and Replacement Guide (NZ)
September 20 2025Home Gadgets Guide: Repair, Maintenance & DIY Tips
Every house runs on a bunch of gadgets – from the boiler that keeps you warm to the extractor fan that clears out cooking smells. When one of them stops working, it can feel like a hassle, but most issues aren’t as scary as they look. Below you’ll find straight‑forward advice that helps you decide if a quick fix will do or if it’s time to call a certified engineer.
Common Issues and Quick Fixes
Fans and extractors are the first things to check. A buildup of grease or dust often slows them down. Turn off the power, remove the cover, and clean the blades with a damp cloth. If the fan still hums but doesn’t spin, the motor may need a simple bearing oil or a new capacitor – both cheap parts you can swap yourself.
Ovens often suffer from a faulty heating element. Look for uneven browning or no heat at all. Unplug the oven, locate the element, and test it with a multimeter. If the reading is off, replace the element – it’s a quick job that saves a call-out fee.
Water heaters collect sediment over time, which reduces efficiency. Flushing the tank once a year clears the buildup. Hook a garden hose to the drain valve, open the valve, and let water run until it’s clear. This simple routine can add years to the heater’s life.
Boilers are a bit more complex because they involve gas. Still, you can spot obvious problems: odd noises, error codes on the display, or a drop in pressure. Check the pressure gauge and top it up if it’s low. If error codes persist, it’s safer to let a certified gas engineer investigate.
When to Call a Professional
If you’ve tried cleaning, testing and the gadget still won’t work, or if you’re dealing with gas, electricity or sealed‑system components, it’s best to call a pro. A qualified gas engineer can safely handle boiler repairs, gas pipe checks and combustion testing. For electrical issues that involve wiring behind walls, a licensed electrician will keep you safe and ensure the work meets local codes.
Another red flag is frequent breakdowns. If a fridge, freezer or dishwasher needs repair more than once a year, the cost of parts and labour may outweigh buying a new unit. Professionals can give you an honest cost‑benefit assessment.
Safety should always be your top priority. Leaking gas, exposed wires or water around electrical panels are not DIY jobs. A quick call can prevent bigger damage and keep your home safe.
Keeping your home gadgets in good shape mostly comes down to regular care and knowing your limits. Clean filters, flush tanks, and run simple checks every few months. When something feels beyond a quick fix, reach out to a trusted local service – they’ll get the job done right and keep your home running smoothly.
