You may also check on the article about Microwave Oven repair by Humberto and Sam: https://jestineyong.com/faulty-big-capacitor-in-microwave-oven/, Want to know about these type of high power capacitor Discharging technique. Completed another basic electronics repair course yesterday for 2 participants.... // Special handling for facebook iOS since it cannot open new windows to build one yourself. All-in-One Computers document.getElementById("af-header-413914580").className = "af-header af-quirksMode"; Hi Parasuraman, at the end you solved the problem and saved a device from the dump. The thermal fuse cuts off power to the microwave if the microwave overheats. Due to the potential for electric shock, it is extremely dangerous to replace the electronic components in a microwave. Only to confirm that the output is correct using the ratio of the voltages you see. When the diode fails, it is often visibly burned out. Only a licensed technician should replace a door switch.). It has Smart Inverter technology, letting you cook at low temperatures and ensuring even heating, and its antibacterial properties help keep germs at bay. For example, you may have inadvertently changed some power settings, resulting in an unexpected mode of operation. The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. As you've said, you have not tested this with any Magnetron circuit. (These Probes originally are free from any additions inside. This high voltage powers the magnetron to heat the food. You disconnect the magnetron,which is your load, and have the secondary winding of the transformer free. Still it seems a dangerous and avoidable way to test and 'really see' if the HV circuit works. It is not necessary to check the full output. Or am I asking a stupid question? postage fee from china to India is 30 usd Albert, you will get the nominal VA power of the indidual transformer you use minus the losses. (“Warning: The microwave oven can store a lethal amount of electricity in its high voltage capacitor, even after the... microwave oven has been unplugged. In case of maintenance, one can discharghe it in advance with a screw driver, without causing damage to the surrounding components. The high voltage capacitor works with the high voltage diode to convert the output of the transformer to DC voltage and to double the output voltage. on the ohm setting on he mutlti meter, check between the pin of the magnetron and the body of it and you your not get any kind of reading... if there is reading, the magnetron is bad and need to be replaced. Connect the high voltage windings with each other and then use one of the primaries as input and the other as output. I only have a doubt: in CRT sets, the high voltage is about 15 kV or even higher. Get information on the LG MJ3965BGS. Systems and managed to repair the Probe that was thrown away. That's it! Even in the event of fear for working with high voltages while a variac is not available, the "poor technician's"-safe method would be to feed the transformer backwards, i.e. I know Paris, but buying them really isn't cheap. Documents: - Owner Manual ( English ) - 15 MB - pdf - MS4296OSS - LG - Specifications Sheet ( English ) OWNER’S manual MICROWAVE OVEN Please read this owner’s manual thoroughly before operating. (Warning: The microwave oven can store a lethal amount of electricity in its high voltage capacitor, even after the microwave oven has been unplugged. So, if the output doesn't respond to the one expected per the voltages ratio, it would reveal a transformer defect immediately. all is cost of costumer Yes, that is the NeoChef™ by LG Electronics (LG).
