If your microwave stops heating, makes strange noises, or the turntable won’t spin, you’re probably thinking about a repair. Before you panic, take a breath and check a few basics. Unplug the unit, look for obvious signs of damage, and make sure the door latch works properly. Most issues are either a blown fuse, a faulty door switch, or a bad magnetron, and each has a simple test you can do safely.
First, the fuse. A blown fuse is the most frequent cause of a dead microwave. You’ll find a small glass tube near the power cord. If the metal filament inside is broken, replace it with the exact same rating – usually 250 V, 2 A. Replacing a fuse costs under £20 if you buy the part yourself, and a local tech will charge about £40‑£60 for labour.
Second, the door switch. The microwave won’t run if the door sensor thinks the door is open. Listen for a click when you close the door; no click means the switch may be stuck. You can test it with a multimeter, but if you’re not comfortable, it’s best to call a professional.
Third, the magnetron. This is the part that actually creates the microwave energy. If you hear a buzzing sound but nothing heats, the magnetron might be failing. Replacing a magnetron is more expensive – parts can run £80‑£120, plus labour. At this point many homeowners weigh repair versus replacement.
Microwaves contain high‑voltage capacitors that stay charged even when unplugged. If you’re unsure about any step, stop and call an expert. A qualified technician will safely discharge the capacitor, diagnose the fault, and give you a clear price before starting work.
Look for a local service that offers a clear quote, guarantees their work, and has good reviews from nearby customers. Northampton Appliance Repairs, for example, provides same‑day appointments, transparent pricing, and a 12‑month guarantee on parts and labour. That peace of mind is worth the extra few pounds.
Cost‑wise, most microwave repairs fall between £50 and £120, depending on the problem. A simple fuse replacement is at the low end, while magnetron swaps push the price higher. If your microwave is older than 10 years, compare the repair cost to the price of a new model. New microwaves now start at around £80 for basic units and go up to £250 for convection models.Before you decide, think about energy efficiency. Newer microwaves use less power and often have better heating distribution, which could save you money on electricity in the long run.
In short, start with the easy checks: fuse, door latch, and power source. If those don’t solve the issue, reach out to a trusted local repair service. Get a written estimate, ask about warranties, and weigh repair costs against buying new. With the right approach you’ll have your microwave back to heating leftovers in no time, without blowing your budget.
