A broken microwave can bring your home or business to a grinding halt. Our guide explores the most common microwave faults, helps you decide whether to repair or replace your appliance, and explains why trusting a local, family-run expert is crucial for a safe and lasting fix. We'll cover everything you need to know about getting a professional, reliable repair in Derby, Nottingham, and Leicester. When Your Microwave Stops, Life Stops With It It’s a moment of pure frustration. At home, it’s the cold cup of coffee, the un-defrosted meal, or the hungry child waiting for their beans. In a professional kitchen, it’s a critical link in the service chain, breaking down, leading to backed-up orders, stressed staff, and unhappy customers. Whichever kitchen you're in, the problem is the same: a vital and incredibly convenient piece of equipment is suddenly out of action. We know how stressful that is. Your first thought might be the cost and hassle of buying a brand-new one. But in many cases, a professional repair is a far quicker, more affordable, and simpler solution than you think. That's where we come in. At Cattermole Electrical , our family has been keeping kitchens working across the East Midlands since 1970. We're here to get you back up and running with a trustworthy, expert service. Common Microwave Problems: A Deeper Look With over 50 years of experience in electrical repairs in Derby and beyond, there are few microwave problems we haven't encountered and solved before. Here are some of the most common faults our engineers diagnose and fix every week. 1. "It's Not Heating My Food" This is the most frequent complaint we hear. You put your food in, the plate spins, the light is on, but everything comes out just as cold as it went in. The Expert Diagnosis: Nine times out of ten, this points to a failed magnetron. The magnetron is the "engine" of your microwave; it’s the component that actually generates the microwaves that cook your food. After years of service, it can simply wear out. It can also be affected by a failing high-voltage diode or capacitor. Our Solution: Our trained engineer can safely test these high-voltage components, identify the exact point of failure, and replace the faulty part. This is a common repair that brings a perfectly good microwave back to life. 2. "The Turntable Isn't Spinning" This is a frustrating one, as it leads to "hot spot" cooking—part of your food is scalding, and the rest is cold. The Expert Diagnosis: The culprit is almost always the small turntable motor that sits underneath the microwave's cavity. This motor can wear out or seize up, especially if a spillage has leaked down into the mechanism. Our Solution: This is generally a very straightforward fix. Our engineer can access and replace the faulty motor, getting your turntable spinning again so your food cooks evenly. 3. "It's Making a Loud, Alarming Noise" Any new, loud, or unusual sound from an appliance is a clear warning sign. This can be a grinding, buzzing, or humming noise. The Expert Diagnosis: A loud humming could be a problem with the high-voltage magnetron or diode. A grinding or rattling sound may indicate a failing turntable motor or a problem with the cooling fan. Our Solution: Don't ignore it. Turn the appliance off and call us. An unusual noise is your microwave's way of telling you something is wrong before it fails completely. We can trace the source of the sound and fix the underlying issue. 4. "The Lights Are On, But Nothing Works" You press the start button, and... nothing. The light may be on, and the clock might be working, but the microwave won't start heating. The Expert Diagnosis: This almost always points to a failed door interlock switch. Your microwave has several safety switches to ensure it can never run with the door open. If one of these switches fails, the microwave 'thinks' the door is permanently open and won't start. Our Solution: We can test the continuity of the door switches and replace the faulty one, restoring your microwave's safe operation. 5. "I See Sparks or Arcing Inside!" This is by far the most alarming fault and a definite "stop and unplug" moment. The Expert Diagnosis: Arcing (sparking) is often caused by a faulty 'waveguide cover'. This is the small, often silver-coloured card or mica sheet inside the microwave. It can get splattered with food, which then burns, causing sparks to fly. In other cases, damaged paint or a faulty part can be the cause. Our Solution: This is a serious safety hazard. Our engineer can identify the cause, replace the waveguide cover, and check the cavity for any other damage to ensure it's completely safe to use again. Safety First: When You MUST Call a Professional We're all for a bit of DIY, but a microwave is one appliance you should never attempt to repair yourself unless you are a qualified professional. Microwaves contain a high-voltage capacitor that can store a lethal electrical charge for days, even after the appliance has been unplugged. Opening the casing without knowing how to safely discharge this component is extremely dangerous. If you experience any of these, unplug the appliance immediately and call an expert: You see sparks or smell burning. The door is broken, damaged, or doesn't close properly. The power cord or plug is damaged. The appliance has been dropped or suffered a heavy impact. Your safety is not worth the risk. Our engineers are trained to work safely with these high-voltage appliances, giving you complete peace of mind. Repair or Replace? An Honest Guide We know the big question on your mind: is it worth the cost of a repair, or should you buy a new one? As a family-owned firm built on trust, we'll always provide you with an honest answer. Here’s what we'd tell you to consider: The Age of the Appliance: A microwave that's only two or three years old is almost certainly worth repairing. If your appliance is over 10 years old and needs a very expensive part, we’ll be upfront and tell you that a replacement might be a more sensible financial choice. The Cost of Repair vs. Replacement: A simple fix like a door switch or turntable motor is far, far cheaper than a new machine. We’ll always provide you with a clear, upfront quote before we begin any work so that you can make an informed decision with no pressure and no hidden charges. We believe in a fair price for a quality job. The Type of Microwave: There's a big difference between a £50 countertop model and a £500 built-in combination or convection oven. These high-end, integrated appliances are significant investments, and repairing them is almost always the smarter, more cost-effective option. The Environmental Cost: Every appliance we send to the landfill has an environmental impact. Repairing a trusted machine is a more sustainable choice, and it's something we're proud to help our customers do. Why Choose a Local Expert?
