Woke up this morning to a fire alarm, a very smoky house and the microwave on fire. Nothing was in it, nobody was using it, just went off. My girlfriend told me last night when she was downstairs that the microwave looked like it was turned off with the clock not working. I thought nothing of it at the time, now I'm thinking some sort of electrical surge happened. We did flip the breaker off on it this morning just to be safe.
Fire was behind the grating on the right side of the microwave, where I'm assuming the motor part is (picture attached). We had to pull out the fire extinguisher from under the sink to put it out.
Airing out the house, no other damage besides just a lot of smoke and of course a broken down microwave.
过了两个小时，又发了一个Email。
I was pretty tired when everything went down this morning. I took a couple more pictures of the microwave. After I woke up. I was able to wipe away the residue off the cabinets as well so the only real damage it seems is the actual microwave.
今早房客发的Email，现在我非常困惑 请教各位大神，这微波炉为什么会着火， 房客的话可信吗？ 房客4月搬入, 迄今为止 修了空调， sprinkers, 和其他一些小修理。交租准时。

把Microwave的厂商到google里面过一把，看看有没有recall incident。e.g. google "GE microwave on fire" etc.
你这个估计是某个relay或switch怀了，微波磁控管magnetron 一直开着空烧事间长了把变压器或者微波磁控管本身烧坏了。这个不值得修了。
我家的大概与你的同款，二十多年了最近还是坏掉了，也是同一个坏法。前几年怀了一次，敲打几下stucked relay又维持了两年（写了一贴但不知怎么没有了

）。Craigslist 上找了个不要钱的，当然要自己修一下，是开关问题。微波炉开关问题很容易修，10块钱买6个，很容易换。我这次是从老的微波炉上拆下来的开关换上的。
买新的5百多，安装又是1-2百。Craigslist上很多不要钱的，有的没坏，有的坏了很容易修。我们老头老太太胳膊没劲举不起over the range，又用上了千斤顶
。
自从第一次修微波炉起，已经修过好几个微波炉了，都修出瘾来了。据说多数都是Sharp做的内部，其他厂家就配个自己的壳，所以都差不多。控制面板那边怎么打开后都差不多的，里面都像微信上传的德国工程师段子那样有个维修指南+线路图，怎么查故障，更换零件号码等等，很好玩。
着火的痕迹基本看不见了，谁会这样清洁？要赔偿不是要保留证据吗？
上面的朋友讲得对，房客的话当不得真，不然你会累死。找起火的原因实在是多此一举。
要是我，根本不用找电工。把旧的拆下来，买个最普通的微波炉，不会超过150元。就放在台面上，免安装，注意不要和电烤炉和冰箱一路电线，防止过载。保险的话，用原来的接电点，但要走电线。
微波炉放在煤气炉灶正上方，后患无穷，使用不便。你端碗汤放进去试试，哪个天才想出的？
