Microwave

[Joe Dutchstar]

Typically I’ve found that, if you have adequate power, and a microwave refuses to energize, it is something simple, burnt thermostat, diode, fuse. That said there are many items that can hurt you inside a micro wave . Capacitors hold enough energy to give you a very bad day if you complete a circuit. if you chose to open the unit up make absolutely sure that the capacitors are drained. A repair manual will go through the steps. Below is a troubleshooting guide I use to cover potential problems

• Diode – converts A/C to D/C
• Door switch – Notifies the rest of the microwave that cooking can occur
• Magnetron – Uses the D/C current to make microwaves. Microwaves cook your food
• High voltage capacitor – Along with the diode, converts A/C to D/C
• High voltage transformer – helps converts volts to power the magnetro
• Thermal Fuse – monitors the microwave for overheating
• Thermoprotector – Also monitors the microwave for overheating. The Thermoprotector will prevent the microwave from starting
• Main control board – This is the brains of the microwave. controls everything from cooking time to cooking power and turntable rotation.

And the number one reason for failure is! The safety switch that detects an improperly closed door. Yup as simple as a misaligned door latch has been the number one fault I have found.
