"In the past few years, several customers reported that they were having an issue with microwaves from a particular manufacturer turning on by itself. Even if the customer hit “cancel” on the microwave, it would come back on. This issue was not a small one. It was discovered after research that a faulty board or switch on the microwave could lead to such an issue. In such a case as this, you should contact the manufacturing company and ask them to replace the board or switch. "
