Yes, the question is these guys. I actually bought a microwave oven for its transformer today, but it is a very nice samsung me86v model. The person I bought got it serviced and they replaced its fuse in the service, but after some use, he says it trips the breaker again and stops working. I checked the switches called door switches. And they seem fine. I just realized that 250v 10A fuse inside is damaged. If I change that fuse again will it solve the problem or there can be anything else?
