Microwave-oven repairs

About the microwave-oven

The oven converts your home electrical power into a high voltage. This is then taken to what is called a magnetron that converts this to radio waves.

The radio waves vibrate the food molecules to create heat which cooks the food. The best way to look after your machine is to do very basic maintenance and this is to keep the internal parts clean and the interior dry.

SAFETY WARNING

Never attempt to repair or troubleshoot your home-appliances unless the electrical power is switched off and the plug removed.

This site or myself cannot accept any responsibility for injury or death following any attempt to follow the advice given within this website.

If you are in any way unsure of your ability to follow the advice then call a qualified electrician or service person. Unplug or electrically isolate the appliance before checking any part of the wiring, or opening the protective covers

The microwave will not operate

1. Always check that the power is on. The unit power indicator light will show this and the clock will be on or display will be flashing.

2. Check that the door switch is operating by opening and closing a few times.

3. Check that control settings have been correctly entered.

4. There is an internal control circuit fault. If you can hear a loud buzzing or but no heating, this indicates a possible magnetron fault.
