Microwave Repair in St. Louis, West & South County, Jefferson and Franklin County

Determining whether to repair or replace your microwave depends on the age, extent of damage, and cost of repair. Microwaves typically last 7-10 years. If your unit is under this age and experiencing issues like uneven heating, strange noises, or failure to start, repairs can be cost-effective. However, if the microwave has significant electrical faults, a damaged magnetron, or repair costs exceed 50% of replacement, a new unit may be wiser. Appliance Repair Masters provides a thorough diagnostic to help you make an informed decision, factoring in safety, efficiency, and long-term reliability.

When a microwave runs but doesn’t heat, common causes include a faulty magnetron, a blown high-voltage diode, or a defective capacitor. The magnetron generates microwave energy, so if it fails, heating stops. Diodes and capacitors regulate electrical flow to the magnetron. Attempting DIY fixes can be dangerous due to high-voltage components. Appliance Repair Masters uses specialized tools and trained technicians to safely diagnose and replace these parts, restoring your microwave’s heating function while ensuring safety and performance.

If your microwave’s turntable isn’t rotating or is making grinding noises, the turntable motor might be failing. This motor ensures food cooks evenly by rotating the tray. A broken motor can lead to uneven cooking and potential overheating of food. Sometimes, the problem could be the turntable coupler or broken rollers, which are simpler to fix. Our technicians at Appliance Repair Masters inspect all components related to the turntable and perform repairs or replacements to restore smooth operation and even cooking results.

No, sparking or arcing inside your microwave signals electrical issues like damaged waveguides, faulty door seals, or metallic objects inside the oven. Continued use can cause fire hazards or permanent damage. If you observe sparks, stop using the microwave immediately and call Appliance Repair Masters. We provide prompt inspections to identify the source of the arcing, repair or replace damaged parts, and ensure your microwave operates safely. Avoid DIY fixes as high voltage and electrical components inside microwaves can be dangerous.

Regular cleaning every 1-2 weeks prevents food residue buildup that can cause odors, smoke, or arcing. Use a mild detergent and avoid harsh chemicals or abrasive scrubbers that can damage the interior coating. Pay special attention to the waveguide cover, which protects the magnetron from food debris. Neglecting cleaning can lead to reduced efficiency and damage over time, resulting in costly repairs. Appliance Repair Masters can also recommend cleaning best practices and perform thorough professional cleanings if needed during maintenance visits.

Common repairs include replacing the magnetron (responsible for heating), fixing door switches that fail to close the circuit, repairing faulty control panels or touchpads, and addressing issues with the turntable motor or light bulbs. Many repairs stem from electrical component failure or physical damage from drops or spills. Appliance Repair Masters diagnoses the root cause quickly, offering cost-effective repairs with genuine parts, ensuring restored performance and extended microwave lifespan in homes and businesses across St. Louis and surrounding counties.

Most repairs, like replacing a magnetron, door switch, or turntable motor, can be completed within 1-3 hours during a single service visit. This timeframe includes diagnosis, parts replacement, and testing. Appliance Repair Masters stocks many common parts, minimizing wait times. Complex repairs or ordering specialty parts might extend the timeframe slightly.

A door that won’t close properly could have misaligned hinges, a damaged latch, or broken door switches. This prevents the microwave from operating since safety interlocks require the door to be fully closed. Attempting to force the door can worsen damage. Appliance Repair Masters inspects door components carefully, realigning or replacing parts as needed. Proper door function is essential for safe microwave operation and to avoid radiation leaks. We ensure repairs restore both safety and functionality promptly.

If your microwave suddenly stops working, first check the power source, outlet, and circuit breaker. If those are fine, the problem may lie in internal components like the fuse, control board, or door switch. Internal fuses blow as a safety measure to protect against electrical faults. Appliance Repair Masters offers thorough diagnostics to identify the failure cause and replace defective parts safely. Avoid attempting repairs yourself as microwaves contain high-voltage elements that pose risks without proper tools and training.
