Basic Microwave Repair?

Hi everyone. I read many web sites about testing and repairing microwave ovens and have concluded that my Sharp microwave has a bad diode and capacitor. I checked the magnetron and, according to what I read, it's probably OK as I get a reading of about .4 ohms across the terminals and it is not shorted to the case. However, I'm wondering if it is possible to test the magnetron with low voltage DC. I assume that what is usually fed into it is 120 VAC rectified which I think will result in about 170 VDC. If that's the case, then could 12 VDC be used just to verify the magnetron still works before spending money on other parts? I ain't gonna do nothin' 'les someone says it's OK and explains how ;-) The sympton right now is that it buzzes and blows the fuse so I'm thinking an open diode and shorted capacitor results in feeding 60 Hz AC to the magnetron thus causing the buzz. Does that sound right? Thanks. NO! From what you wrote it shows your lack of the most basic electronics skills. You have no business trying to fix it yourself unless you are planning a suicide anyway. |
