Magnetron Replacement – Quick, Affordable Microwave Repair in Rugby
If your microwave makes loud buzzing, sparks, or just won’t heat food, the magnetron is probably the culprit. The magnetron is the part that creates the microwaves that heat your meals. When it fails, the whole appliance is useless. Knowing the signs, the cost, and the best way to get it fixed can save you time and money.
What is a Magnetron and Why It Fails?
A magnetron is a metal tube with a magnet inside that turns electricity into microwave energy. Over time the tube can wear out, the magnet can lose its strength, or the internal seals can crack. Common reasons for failure include:
- Frequent use – every time you heat food the magnetron works hard.
- Power spikes – sudden surges can damage the tube.
- Moisture inside the unit – steam can corrode the component.
- Old age – most magnetrons last 5‑10 years before they start to falter.
When the magnetron stops working you’ll notice one or more of these symptoms:
- Food stays cold or lukewarm.
- Weird smells or a metallic taste.
- Visible sparking inside the cavity.
- Loud humming or buzzing that never stops.
If you see any of these signs, stop using the microwave – a damaged magnetron can become a safety hazard.
How Much Does a Magnetron Replacement Cost?
The price of a new magnetron varies by brand and model, but most parts run between £30 and £80. Labor is usually the bigger part of the bill because the technician has to open the unit, test the part, and safely reinstall it. In Rugby, a typical replacement job costs between £120 and £180 all‑in, including the part and labour.
Why pay a professional? A DIY swap might seem cheap, but you need the right tools, a calibrated multimeter, and a safe way to discharge the high‑voltage capacitor. Mistakes can lead to electric shock or further damage to the microwave. A qualified tech follows strict safety procedures, guarantees the work, and can spot other hidden problems that could cause a repeat failure.
Our Rugby team offers same‑day service for most magnetron replacements. We’ll arrive with the correct part, finish the job in under an hour, and run a full test to make sure the microwave heats properly before we leave.

In most cases a magnetron replacement revives a microwave for another 5‑7 years, which is far cheaper than buying a new unit. It also reduces waste, so it’s a win for your wallet and the environment.
