If your microwave suddenly stops heating, starts sparking, or makes strange noises, you’re probably wondering if you can sort it out yourself. The good news is that many common microwave problems have simple solutions you can try at home. The bad news? Some fixes need a qualified tech, especially when the magnetron or high‑voltage parts are involved. Below we break down the most frequent faults, quick DIY steps, and clear signs it’s time to call Hinckley Home Appliance Repair Services.
Microwave won’t heat. The first thing to check is the door latch. If the door isn’t closing properly, the safety switch stops the oven from powering up. Clean the latch and the surrounding seal, then try again. If the door is fine, the next suspect is the fuse. Unplug the unit, locate the fuse (usually a small glass tube near the power cord), and look for a broken filament. Replacing a fuse is cheap and easy, but be sure to use the same rating.
Sparking or arcing inside. Lightly charred food or metal fragments can cause sparks. Remove the turntable, clean the interior with a mild detergent, and inspect the waveguide cover (the plastic piece above the magnetron). If it’s cracked or dirty, replace it – it’s a low‑cost part that stops arcing. Never microwave metal; even a tiny foil scrap can create a dangerous arc.
Turntable not rotating. Most models use a small motor underneath. Check that the roller guide is free of debris and that the motor’s gear isn’t stripped. If the motor hums but the plate stays still, the motor likely needs replacement. This is a bit more involved and may be best left to a professional.
Unusual noises – humming, buzzing, or clicking. A humming sound is normal; it’s the magnetron doing its job. If it turns into a loud buzz or repeated clicks, the magnetron may be failing. Magnetron failure is a classic sign that the microwave is beyond a simple DIY repair. Replacing a magnetron costs a fair amount and involves high voltage, so call a qualified technician.
Remember to always unplug the microwave before inspecting internal parts. Safety switches can hold a charge even when the unit is off.
On average, a home microwave lasts about 8‑10 years. Heavy use, like daily reheating for a family of four, can shorten that lifespan. Keep an eye on three warning signs:
When any of these appear, weigh repair cost against the price of a new microwave (usually £80‑£150 for a mid‑range model). If the repair bill is more than half the cost of a new unit, replacement makes sense.
Regular maintenance can stretch your microwave’s life: wipe the interior after each use, avoid slamming the door, and keep the ventilation slots clear of dust.
