How to Fix Samsung Microwave Error Code C-10 (Easy Steps)

Imagine heating your food when your Samsung microwave shows error code C-10—so annoying! But don’t worry, this problem is usually easy to fix. Like restarting a frozen phone, a quick reset or simple check can solve it. In this post, I’ll show you easy steps to fix the C-10 error fast, saving you time and money. Let’s fix it!

Understand What Error Code C-10 Really Means

When you see the C-10 code on your Samsung microwave, it means there is a problem with the humidity sensor. This sensor helps the microwave understand the moisture level in your food. If it stops working or sends the wrong signal, your microwave can’t cook correctly and shows this error.

Many people think the microwave is broken, but that is not true most of the time. The problem usually comes from the sensor being dirty, disconnected, or faulty. Sometimes, just cleaning or checking the connections can fix it.

First, unplug your microwave from the wall to keep things safe. Let it sit for a few minutes before you start checking inside. The humidity sensor is usually found inside the microwave near the top, or behind the control panel. If you are not sure, you can check your microwave manual.

Take a soft cloth and gently clean the sensor. Do not use water or spray. Just wipe it carefully and make sure nothing is blocking it. If the sensor looks damaged or loose, you may need to reconnect it or replace it.

If the error still shows up after cleaning, it could be that the sensor is not working anymore. You can buy a new sensor online for your Samsung model and install it by following video guides or instructions that come with it. If you are not sure, you can call a technician.

• C-10 means the humidity sensor has a problem
• Unplug the microwave first before checking
• Clean the sensor carefully with a soft dry cloth
• Check for loose or broken connections
• Replace the sensor if needed

Unplug the Microwave and Wait a Few Minutes

Before doing anything inside your microwave, always unplug it from the wall. This is very important. Even when it is turned off, it can still have electricity inside. You do not want to get shocked.

Once you unplug it, let it sit for about 10 minutes. This gives the microwave time to reset itself. Many times, a simple restart can make the C-10 error go away. Just like how your phone starts working better after you restart it, the microwave might do the same.

While waiting, check the power cord for any damage. Sometimes a broken or bent plug can make the microwave act strange. If the cord looks fine, and you plug it back in after a few minutes and still see the error, then you can start checking the inside.

Make sure your hands are dry, and you are working in a bright place where you can see clearly. Safety always comes first. Now you’re ready to look at what is happening inside.

• Always unplug the microwave before doing anything
• Wait at least 10 minutes to allow it to reset
• Check the power cord for damage
• A simple restart might fix the error
• Make sure your hands are dry before touching anything

Check the Humidity Sensor Location and Clean It

The humidity sensor helps the microwave know how much moisture is in the food. It uses this information to heat things correctly. When this sensor has a problem, the microwave shows the C-10 error code.

Most Samsung microwaves have the humidity sensor near the top of the inside, usually near the light or vent area. If you don’t know where yours is, look in the manual or search online using your microwave model number.

To clean it, use a soft, dry cloth. Do not use water, spray, or harsh cleaners. Just gently wipe the sensor. If it is dusty or covered in grease, it will not work well. Sometimes, just cleaning it can fix the problem.

If the sensor is behind the control panel, you may need to unscrew the panel. Be very careful when doing this. If you see that a wire is loose or disconnected, try to gently connect it back. If anything looks broken or burned, the sensor may need to be replaced.

Sensors can wear out after years of use, just like any other small part. If cleaning does not help, replacing the sensor is the next best thing.

• Humidity sensor is usually near the top inside the microwave
• Clean it using only a soft, dry cloth
• Never use water or cleaning sprays on the sensor
• Reconnect any loose wires gently
• Replace the sensor if it looks damaged or cleaning does not work

Reset the Microwave Settings

Sometimes the C-10 error is not from the sensor itself but from the microwave software getting stuck. Like a frozen phone or computer, resetting it might help.

After unplugging the microwave and plugging it back in, try to do a full reset. For most Samsung microwaves, press and hold the “Stop/Cancel” button for 3 to 5 seconds. If your model has a reset option, use that instead.

Doing this clears out any saved errors or wrong signals from the sensor. If the error disappears after this, then you do not need to replace anything.

If the error comes back after resetting, then the sensor or wiring may be the real problem. But it’s always worth trying a full reset before doing any repairs.

Also, try not to use any special cooking modes right after resetting. Just test it by heating a cup of water for 1 minute. If that works fine, the problem may be fixed.

• Do a full reset by pressing the stop/cancel button
• Reset can fix stuck software issues
• Test it by heating simple items first
• Use basic settings after resetting
• If the error comes back, check the sensor again

Inspect the Sensor Wire Connections

The humidity sensor works with tiny wires that send signals to the control board. If these wires are loose or broken, the sensor can’t talk to the microwave.

To check the wires, you need to open the control panel. Always unplug the microwave first. Then carefully remove the screws and slowly open the panel. Look for the wires connected to the sensor.

These wires are very small and sometimes get loose from shaking, moving, or heat. If you see any wire out of place, gently plug it back in. Use your fingers and do not force anything.

If the wires look burned or broken, you may need to replace them or the sensor itself. You can order new wires or a new sensor online using your microwave’s model number.

Try not to bend or pull the wires too hard. If everything looks fine, close the panel, screw it back, and test the microwave again.

• Open the control panel carefully after unplugging
• Check if any sensor wires are loose
• Reconnect loose wires gently
• Do not pull or bend the wires too much
• Replace the sensor or wires if they look damaged

Replace the Humidity Sensor if Needed

If cleaning and checking the wires did not work, your sensor might be faulty. A bad sensor cannot send the right signal, so the microwave shows C-10 again and again.

You can buy a new humidity sensor online. Make sure to buy the correct one for your Samsung model. If you are not sure, check your manual or search the model number on the product label.

To replace it, open the control panel, remove the old sensor, and put the new one in its place. The sensor usually has a small plug you can pull out and replace. Be gentle, and do not break anything while doing it.

After installing the new sensor, screw the panel back, plug in the microwave, and try using it. The error should be gone now.

If you still see the error after replacing the sensor, then the control board might be the issue. In that case, calling a technician is a good idea.

• Buy the correct sensor for your microwave model
• Carefully remove the old sensor
• Plug in the new sensor in the same place
• Do not force or break the connector
• Test the microwave to see if the error is fixed

When to Call a Technician

If you have tried everything above and the C-10 error still shows, it’s time to ask for help. A technician can check things that are hard to reach or test parts with special tools.

Sometimes the problem is in the control board, not just the sensor. That is harder to fix at home. Also, if your microwave is under warranty, trying to fix it yourself can cancel the warranty. So it’s smart to check first.

A technician can also test the power system inside the microwave to make sure everything is working safely. If they find that the control board or sensor is fully dead, they can replace it for you.

Calling for help might cost more, but it can save time and avoid mistakes. If your microwave is old and needs many repairs, sometimes it’s better to buy a new one.

• Call a technician if nothing else works
• They can test parts you cannot check at home
• Protect your warranty by checking first
• Fixing control board needs expert hands
• Sometimes it’s cheaper to replace the microwave
