If your microwave stops heating, sparks, or starts making odd sounds, you’re probably wondering if you can fix it yourself or need a pro. The good news is many problems are simple to diagnose and solve without opening the cabinet. The bad news is some faults involve high‑voltage parts and are best left to qualified technicians. Below we break down the most common issues, give you step‑by‑step checks, and tell you exactly when to call Bognor Regis Appliance Repair Experts.
1. Microwave won’t heat. The first thing to check is the door latch. If the door sensor isn’t engaged, the unit will refuse to run. Open and close the door firmly a few times and listen for the click. Next, see if the control panel lights up. If the display works but there’s no heat, the magnetron is the usual suspect. Testing a magnetron requires a multimeter and knowledge of high voltage, so most homeowners stop here and call a professional.
2. Sparking inside the cavity. Sparks usually mean there’s a metal object or a damaged waveguide cover. Remove any plates, crisper trays, or metal twist‑ties. If the interior walls look blackened or the waveguide cover is broken, replace the cover. It’s a cheap part and can be swapped in under an hour.
3. Turntable stops turning. First, pull the turntable out and check the roller guide for debris. Clean it with a damp cloth. If the motor hums but the platter doesn’t move, the motor coupler may be worn out. Replacing the motor is a bit more involved, but many DIY videos show a quick disassembly.
4. Unusual noises. A humming sound is normal, but rattling or buzzing often points to a loose fan blade or a failing high‑voltage capacitor. Turn the microwave off, unplug it, and give the back panel a gentle shake. If you hear something moving, the fan may need tightening or replacement.
5. Error codes on the display. Most modern microwaves show a code like “F4” or “E1”. Look up the model’s manual online – the code usually points to a specific sensor or thermostat issue. Resetting the unit by unplugging for two minutes can clear minor glitches.
Even with the best DIY spirit, there are clear red flags that say “call the experts”. If you suspect a problem with the magnetron, high‑voltage transformer, or capacitor, stop. These components store up to 5,000 volts and can give you a serious shock. Also, if the microwave leaks smoke, smells burnt, or the door seal is cracked, a professional repair is safer and often cheaper than a full replacement.
