Microwave Lifespan: What to Expect and How to Make It Last

Most microwaves run between five and ten years before they start acting up. That range isn’t set in stone – how often you use it, what you cook, and how well you look after it all play a part. If you’ve got a cheap unit or you run it daily, expect the clock to tick faster.

Signs Your Microwave Is Near the End of Its Life

Watch out for these clues: uneven heating, rattling noises, sparks inside, or a door that won’t seal properly. If the turntable stops turning or the display flashes error codes, the internal parts are probably wearing out. A blown fuse that keeps happening even after a quick fix is another red flag – the cost of a new fuse can be low, but repeated failures hint at deeper problems.

When you notice any of these issues, it’s time to decide: repair or replace? A simple repair like swapping a blown fuse usually costs under £30. Anything more complex – a bad magnetron or capacitor – can run £80‑£150, which often eats up a good chunk of a new microwave’s price.

Easy Maintenance Tips to Stretch Your Microwave’s Years

Cleaning is the cheapest way to extend life. Wipe the interior after each use, especially after heating splatters. Keep the turntable and its roller clean so it spins smoothly. Check the door seal weekly; a cracked seal lets microwaves leak and forces the unit to work harder.

Avoid metal utensils and foil – they cause arcing that can damage the waveguide cover. Use microwave‑safe containers and don’t overcook food; burning can scorch the interior and create permanent odors.

Give the vents a once‑a‑month brush‑out. Dust builds up, blocks airflow, and makes the motor overheat. If you hear the fan humming louder than usual, it’s a sign the vents need attention.

Finally, don’t ignore the power cord. Pull the microwave out only by the handle, never the cord, and replace the cord if you see cracks. A healthy cord means fewer trips to the breaker and less chance of a short.

Following these simple steps can push a ten‑year microwave into the 12‑year range, saving you money and hassle. If a problem slips past your DIY fixes, a local pro can diagnose it fast.
