Question about Daewoo KOR-630A Microwave Oven
I have checked the door switches all are working properly.the m/wave will start and run with heat for any where 5 minutes to a day of useing it then it will blow the fuse and trip the breaker. the tech i bought the fuses from said the door fuses would make it blow the fuse. so i ohmed them and all check out.why would it work more one day and blow quickly on other days? i have put 5 fuses in it 2 after checking door switches any ideas thanks
It's important that the door switches are clean, solidly mounted and operating smoothly. Sometimes as a switch ages, goes bad, or gets clogged with grease, it can be "laggy", and can allow a short that can blow the fuse and/or breaker. They can certainly be intermittent. Since it's blowing the breaker too, that usually indicates door switch trouble, so the door switch mount may be loose or broken. Beyond that, there is a chance that your magnetron or high voltage transformer is going bad, but I strongly suspect a door switch, mount, bent door, etc. first. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk
