The most common reason why your Samsung microwave runs but doesn’t heat food is because it is in Demo mode, which is used to show off microwaves without activating their magnetron. The magnetron is the part that generates microwaves that heat up your food.
But don’t worry, there are other possible causes and solutions for this issue, and I’m going to share them with you in this blog post. I love my Samsung microwave, and I always use it to make quick and easy meals, snacks, and drinks. But sometimes, it acts up and doesn’t heat my food properly. That’s why I learned how to troubleshoot it and fix it myself.
So let’s get started!
The first thing you should do if your Samsung microwave runs but doesn’t heat food is to check if it is in Demo mode. This mode is used on retail showroom floors to show off microwaves without activating their magnetron. The microwave will run normally, but it won’t heat anything.
An easy way to test for Demo mode is to set a cooking time and start the microwave. In Demo mode, the timer counts down much faster than usual.
If your unit is in Demo mode, turn it off by following these steps:
If your user manual does not mention Demo mode, or if your microwave is counting down faster than usual but not heating, visit our Support Center to request service.

The door switch, the fuse, and the thermostat are safety devices that prevent your microwave from overheating or running when the door is open. If any of them are faulty, your microwave will run but not heat food.
To check these components, you’ll need a multimeter (a device that measures voltage, resistance, and current) and some basic tools. You’ll also need to unplug your microwave from the outlet and remove its cover by unscrewing its screws.
Here’s how to check each component:

The capacitor, the diode, and the transformer are components that help convert the AC power from the outlet into DC power for the magnetron. If any of them are faulty, your microwave will run but not heat food.
To check these components, you’ll need a multimeter and some basic tools. You’ll also need to unplug your microwave from the outlet and remove its cover by unscrewing its screws.
WARNING: The capacitor can store a high voltage even when unplugged. To discharge it safely, use a screwdriver with an insulated handle and touch its blade across both terminals of the capacitor. You may hear a loud pop or see a spark. This is normal.
