Troubleshooting and Repairing a Faulty FPC Membrane Key Switch in a Microwave Oven (Part II)

When purchasing a microwave oven, it is important to consider some basic requirements. Firstly, microwave ovens should have the "CCC" certification mark along with the corresponding factory code and certification number. This certification is a national compulsory safety certification and ensures the product's quality and safety. To verify the authenticity of the certification marks and certificates, consumers can visit the official website of the Certification and Accreditation Administration of China and check the certification online.

Additionally, it is essential to check whether the product comes with a complete set of documents including the instruction manual, certificate, warranty card, and accessories. These documents provide important information about the product and its warranty coverage.

Furthermore, it is crucial to carefully examine the product's logo and instruction manual. According to the National Mandatory Standard.21 - "Special Requirements for Safe Microwave Ovens for Household and Similar Electrical Appliances," microwave oven products should have clear and standardized identification. This includes information such as the trademark, model, specifications (such as capacity), rated voltage, rated input power, symbol of the power supply nature, manufacturer's name, and rated output power. The instruction manual should also contain warnings to prevent misuse and detailed cleaning methods. Moreover, the operation switch logo on the product should be clear and reliable.

By considering these basic requirements, consumers can ensure that they are purchasing a microwave oven that meets the necessary safety standards and provides reliable performance.
