Samsung Microwave Not Heating Enough

This high voltage powers the magnetron to heat the food.

Samsung microwave not heating enough.

The diode converts the a c power output of the transformer to d c doubling the voltage to nearly 5 000 volts. If the diode burns out the magnetron won t receive enough voltage to operate preventing the microwave from heating. A microwave that is not turning on or is turning off by itself is usually caused by overheating or a low power supply. We bought all new samsung appliances just over a year ago and every single one has been repaired.

If the diode burns out the magnetron won t receive enough voltage to operate preventing the microwave from heating. However if your microwave doesn t heat up at all it could be in demo mode. This high voltage powers the magnetron to heat the food. The microwave also won t heat if it does not have enough clearance or ventilation.

When the diode fails it is often visibly burned out. This applies to both regular microwave heating and convection heating. If the microwave turns on but does not heat checking a few settings and the installation will help resolve the issue. My samsung microwave also will not heat.

The only thing worse than a samsung is their support. You can check your microwave for signs of overheating and power loss or disable demo mode to solve the issue. Quick troubleshoot and what you may need to fix video. I contacted support and they said my warranty was up two months ago but offered no assistance to resolve the issue.
