Hi. We have a GE Spacemake XL that came with our house. It quit working completely in the middle of cooking. Nothing was working at all and the outlet and breakers were fine. My husband replaced the fuse in the microwave, plugged it, and it seemed to work again...until he tried to heat something up. Again is seemed to blow out, but this time everything else is still working (like the clock, light, fan...). What should we do now? Thank you in advance for your help.
