Condensation forms on the microwave door

Your microwave's door isn't completely sealed so when condensation forms on the outside, some of it may get inside or between the glass panes. The most common form of condensation on the inside comes from the food you're cooking.

Inside the microwave

It is normal for condensation to form on the inside of the microwave, especially when you are cooking food with a high water content. This includes condensation that forms between the glass panes. The condensation will dissipate in time. You can also leave the door open to help it dissipate faster.

Outside the microwave

Condensation forming on the outside of the microwave comes from outside of the microwave. This is most common with over-the-range microwaves when cooking or boiling water on the cooktop below it. Some of this condensation may get inside the microwave as well, or between the door and the glass. Using lids on your cookware will reduce this type of condensation, and running the hood vent while cooking will help as well.

Vent fan is weak on Samsung over-the-range microwave

The vent fan on your over-the-range microwave is useful for keeping smoke and steam clear from the microwave. It will even turn on automatically if the microwave is getting too hot. But if the fan strength isn't strong enough to hold up a napkin, you may feel like it's not working. Fortunately, there's an easy way to tell.

Microwave turns on by itself

If your microwave turns on by itself after you close the door you may need to clean the door, check the latch, or ensure that the door is closed all the way. But if your cooktop lamp will not turn off, then it may just be wet from recent cooking. Follow this guide to get things back to normal.

Samsung microwave does not turn on or turns off by itself

If your microwave is not turning on, or if it is turning off by itself, it could have overheated. When a microwave has been in use for a long time and overheats, just give it 30 minutes to cool off and then try to use it again. Otherwise, you'll need to check the light, the outlet, and the power cord.

Samsung microwave is not heating or has stopped working

When a microwave isn't starting or heating, the most common reason is because it is in Demo mode. This mode is used on retail showroom floors to show off microwaves without activating their magnetron. The microwave also won't heat if it does not have enough clearance or ventilation. If the microwave turns on but does not heat, checking a few settin

Turntable does not rotate and is making noise

The turntable is designed to, well, turn. The continuous rotation generally assists the microwave in providing more even heating of your food. When it's not rotating correctly, there's often a grinding noise as well (or the setting is turned off). A dirty track or roller ring can also cause it to get stuck. Finally, make sure it's positioned correc
