Causes of the SE code on Samsung Microwaves

There are several potential reasons why your device might display the SE code. Here are the most common ones:

• Door Switch Malfunction: Every microwave has a detector that is specifically designed to sense when the appliance door is open or closed. In some cases, the door switch may malfunction or stop working, resulting in the Samsung microwave showing SE.
• Sensor Failure: The device has multiple sensors, including humidity, temperature, and voltage ones. When these instruments stop working, the display shows an SE code to prevent the oven from operating.
• Control Board Issues: The control board is the microwave's mastermind, in charge of managing all its functions. If it misfunctions or fails to provide the necessary electrical power, you will see SE on the display.
• Magnetron Issues: The magnetron is one of the critical elements of a microwave oven, which produces the microwave radiation required for cooking. Thus, if this part fails or encounters any issues, the system will refuse to work and display the SE code to ensure safety.
• Power Supply Problems: At times, breakdowns in the system of electricity supply can trigger the Samsung microwave SE code on display as a safety measure.
• Overheating: An SE code can be an indication that the microwave exceeded its heating limit or was affected by other factors.

As you can see, the SE code is a safety mechanism intended to prevent major technical issues and safety hazards from trying to operate a faulty appliance.
