How to replace the membrane switch of microwave oven?

Unknowingly, microwave ovens quickly entered people's sight of life and became a must-have household item for almost every household. For some good brands of microwave ovens, such as Galanz microwave ovens, after a long period of use, there are often no problems except for some minor problems with the membrane switch. So how do we deal with and solve these problems.

Microwave oven membrane switch replacement steps

1. Accessories: Purchase the required microwave oven membrane switches from home appliance merchants or membrane switch manufacturers. The purchased membrane switches can reduce the external requirements, but the circuit logic of the membrane switches must be consistent with the existing ones to avoid membrane switches. The line is garbled, and the key is invalid;

2. Disassembly: Use a screwdriver to disassemble the case (if it is a film panel without lines), you can directly tear up the film panel, and stick the panel on according to the position of the panel buttons. If it is a film switch with lines , it is necessary to disassemble the casing;

3. Assembly: Membrane switches with circuits are now used in microwave ovens. There are no more than two types, one with a connector head and the other without a connector head. The assembly methods are the same. Just pull out the interface of the PCB board, first install the panel, and at the same time pass the lead wire connected to the PCB board through the line hole of the chassis

Then tear off the double-sided tape on the back of the membrane switch, combine the panel and the casing according to the corresponding position, then connect the lead wire to the interface of the PCB board (insert it in), then assemble the removed parts back, Good screw and you're done.

The replacement of the microwave membrane switch is relatively simple and does not require certain technical content. Generally, buying a membrane switch on the Internet and then replacing it can be solved for more than ten yuan. This is compared to asking a professional master to perform this simple basic operation. In terms of paying a small salary, it is undoubtedly a lot more cost-effective. I hope this article can solve the problem of membrane switch for you.
