Look at the oven now to see how it shines like new and ready to cook food again! In the meanwhile creating the possibility like you said to destroy something that was not defect before. } All-in-One Computers First and most important is to secure proper isolation against any leakage of the secondaries to their external environment. If any of the door switches does not have continuity, replace it. If there is no high voltage (no arc), the magnetrom must be OK, and the work shall be focused in the circuit that generate this HV (transformer, HV diode or the HV capacitor. It is still unclear dear Parasuraman S to me how and why you should blow a Fuse for that test. For example, you may have inadvertently changed some power settings, resulting in an unexpected mode of operation. As this happens, turn-off immediatelly in order not to damage the surrounding components. But this is easy for anyone to verify. That's all. here is an easy way to check the magnetron. (Warning: The microwave oven can store a lethal amount of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. Please give a support by clicking  on the social buttons below. (optional, MS233**** Except we use two Transformers in line (Output to output) so I take it that the total Power of such a Isolation Transformer would decrease because of it? But if none of the components other than the Magnetron tube itself were defect, it maybe only could have been a broken Tube Filament or something broken inside the Magnetron Tube without making any Short Circuit to Ground. So unit was sent to repairer where it still is waiting for parts and repair. Poor after sales help from LG and a product that has failed after 7 months. (Please see the picture above). This high voltage powers the magnetron to heat the food. Amir Mukhtar Ashrafi This is my preferable testing method for cases like the one of this article.

See : http://www.microtechfactoryservice.com/xformer.html (Caution: The microwave oven can store thousands of volts of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. And I have a question that I best ask you since you are an expert in repairing and building Transformers: Is het possible to build a very big and dirt cheap isolation transformer by just using two Magnetron Transformers connected with each others Outputs together? In any case I don't consider it a safe test to perform,due to the much elevated power available in these cases. The high voltage diode is located near the magnetron and the high voltage capacitor, so access will require removal of the cabinet. Does it matter if you swap the connections on the 'F' and 'FA'? Got 2M214 instead of 2M213 and I learnt from my friends that it was ok. The water should reach 60 degrees Celsius. The method suggested for this purpose (that I use without problems) is as follows: disconnect the filament plug and then power on the set. This high voltage powers the magnetron to heat the food. The second thing is to use exactly the same type of transformers, for proper matching of the coil impedances. (This was an idea given by my techie friends). (adsbygoogle = window.adsbygoogle || []).push({}); Interesting repair,nicely presented as well. First they step up the voltage to be sent in long distances where it will be consumed after stepping it down to the usual nominal grid voltages. })(); That's it!
