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

When purchasing a microwave oven, it is important to check its appearance. The appearance should be flat and smooth, with a uniform color and no obvious color difference. Additionally, it is crucial to pay special attention to the sealing condition of the door and whether the door interlocking device is functioning properly.

To further assess the performance of the microwave oven, a water test can be conducted. Simply add an appropriate amount of water to a glass and place it inside the microwave. After energizing the microwave oven, observe how quickly the water heats up. The shorter the heating time, the higher the water temperature, indicating better heating performance.

Furthermore, it is advisable to touch the housing of the microwave oven after it has been running for a while. If the housing feels hot, it suggests poor heat dissipation conditions.

When choosing a microwave oven, it is recommended to opt for well-known companies with a larger scale, better product quality, and superior service. These companies typically have stricter quality control measures for raw materials, parts, and products. They also possess advanced production equipment and maintain high levels of enterprise management. As a result, their products offer guaranteed quality and after-sales service.
