Galanz microwave oven is not responsible for maintenance after the warranty period?

I am also engaged in after-sales work. Please pay attention to the words on the warranty card, the product is maintained for life, not for life, but for free during the warranty period. In the case you mentioned, you need to carefully identify what changed the voice at work. If the sound gets louder, it is that the magnetron is broken. If the sound becomes smaller, it proves that the magnetron is not working, and the transformer or high voltage fuse is broken. But it does not rule out the problem of capacitance. Based on this, the fault can be roughly judged. Just call to ask about the approximate cost and determine whether it is worth repairing.
