How does microwave power level work?

Each power level gives the microwave energy for a certain percent of the time. Power level 7 is microwave energy 70\% of the time. Power level 3 is energy 30\% of the time. Most cooking will be done on High which gives you 100\% power.

Why do microwaves have different power levels?

Manufacturers use different lengths of time in the cycle of their particular microwave oven. The shorter the cycle, the more gentle the action of the microwave cooking. The longer the cycle, generally the more uneven the cooking will be at reduced power levels.

Why does my microwave sometimes not heat?

If your microwave oven doesn’t heat, you may have a problem with the magnetron. This component is part of the high voltage circuit and provides the microwaves that generate the heat.
