Won't turn on: If the microwave won't turn on, it could be due to a faulty power source, a broken fuse, or a malfunctioning door switch.
Runs but doesn't heat: If the microwave is running but not heating food, it could be due to a faulty magnetron, a damaged diode, or a malfunctioning capacitor.
Sparks: If you see sparks in the microwave, it could be due to a metal object inside the microwave, a damaged waveguide cover, or a malfunctioning magnetron.
Plate won't rotate: If the microwave plate won't rotate, it could be due to a broken or damaged turntable motor, or a malfunctioning roller guide.
Makes strange noises: If the microwave is making strange noises, it could be due to a faulty motor, damaged fan blades, or a malfunctioning drive bushing.
It's important to follow the manufacturer's instructions for use and maintenance to keep your microwave functioning properly. If you experience persistent microwave problems, contact a professional for assistance.
