6 Reasons Why Your Samsung Microwave Won’t Turn Off

The good news is that you know that your microwave is definitely working. The bad news is that you can’t get it to stop. If your Samsung microwave keeps on running and running relentlessly, then something’s up. 

So what can you do to get your microwave to turn off? Take a look at the following 6 tips. They will go through the reasons why your microwave is running a marathon and what you can do to call it a break and turn it off.

Reason #1 The Control Panel Needs Cleaning

Your Samsung microwave is running just fine, it’s getting it to stop running that’s the issue. It could be the control panel that is to blame here. 

You should be able to alter the actions of the microwave via the control panel. You should not have to use excessive force to do so. The buttons on the microwave should enable you to alter the running time of the appliance and, of course, get it to stop when you wish. 

If the control panel is dirty, it might not detect your fingers. This may prevent it from stopping when you want it to. Here’s what you can do to fix this problem:

1. Wipe the control panel down with a damp cloth
2. Dry the control panel
3. Test the microwave

You should clean the control panel periodically to prevent this from happening again.

NOTE: Some of the latest Samsung microwaves have capacitive touch panels. The control panel is non-responsive if you are wearing gloves. It will only respond to the touch of a bare finger with sufficient contact area. If you having a problem with your capacitive touch panel you may need to contact Samsung.

Reason #2 It Needs Resetting

Does your microwave keep running non-stop? Then this might be a sign that the unit needs resetting. Sometimes, electrical equipment needs resetting in order to clear any glitches or bugs in the system. These often occur when there is a power outage or another electrical fault. 

Here’s how you can reset any Samsung microwave:

1. Unplug the microwave or turn it off at the circuit breaker
2. Keep the microwave unplugged for 60 seconds
3. Plug it back in or turn the power back on at the circuit breaker
4. Test the microwave

Reason #3 Control Lock Is On

Some Samsung microwaves have a control lock. While the lock is on, you will not be able to use the other buttons. The control lock is a safety feature to prevent children from tampering with the microwave. 

Do you think that your microwave’s control lock was turned on accidentally? Then here are a couple of steps that will help you to turn it off.

1. Press the “CLOCK” and “MORE/LESS” buttons simultaneously for 3 seconds
2. The control lock should deactivate immediately
3. Test the microwave by pressing other buttons

Some buttons on your microwave will not respond while certain functions are being used. Wait for the function to finish in order to restore normal use to the control panel. To find out which functions these are, you should see your user manual. 

NOTE: If you are not sure where your user manual is, you can find it online. Type in “[YOUR MODEL NUMBER] Samsung microwave manual PDF” into an internet search engine to find it. Here’s an example:

You can then search the manual for instructions on different functions.

Reason #4 The Door Or Latch Needs Cleaning

Does your microwave keep running after you close the door? Then the fault might lie, not with the electrics of the microwave but rather within the door or the latch. 

To fix this problem, follow these steps:

1. Plug the microwave out
2. Wipe down the door and the microwave with a damp cloth
3. Wipe down the door’s latch mechanism with a damp cloth
4. Inspect the latch mechanism. If any part of it is broken, replace it.
5. Plug the microwave back in to test it

Reason #5 The Lamp Needs Time to Dry

Does your Samsung microwave’s cooktop lamp stay on even after the unit has stopped heating? Then do not be alarmed as this is normal. The lamp might still be wet after recent cooking and will turn off when it dries. If the lamp turns off on its own after drying, there is nothing to worry about. 

If the lamp doesn’t turn itself off after drying, you might want to try resetting the microwave. You can do this by following these steps:

1. Unplug the microwave or turn it off at the circuit breaker
2. Keep the microwave unplugged for 60 seconds
3. Plug it back in or turn the power back on at the circuit breaker

Reason #6 There Is An Error Code

If none of the above has helped you to stop your microwave from running then it’s time to look for specific problems. Check the microwave’s control panel display for error codes. If there’s an error code, you can look it up to pinpoint and fix its exact problem.

Smart microwaves are able to self-diagnose their problems in most cases. If you’re seeing an error code, you can check the problem in Samsung’s error code database. Here you will find a list of the most common Samsung error codes. You’ll also see some handy instructions that will help you fix the problems. 

Still Stuck?

You’ve cleaned the microwave and checked for error codes. You’ve even restarted your microwave. But no matter what you try, you cannot seem to get it to stop running. Now, what should you do? 

There are a couple of other issues that your microwave could have. There could be a problem with the thermostat or with the door switches. There could also be an electrical issue with the control board or with the fan’s rotary mechanism. But unfortunately, these are a little trickier to fix.

If you have tried all of the other steps in this article but haven’t managed to repair your microwave, you should call an electrician as there seems to be a more complex issue at hand. The technician should be able to pinpoint the problem and repair it for you.
