how to fix lg microwave not heating

If the magnetron burns out, the microwave won’t heat. It is to make troubleshoot simple, that is all! With a screwdriver in contact with the metalic part (chassi) of the MW oven, bring the tip of the screwdriver closer (without touching) to the filament connector (or a portion of wiring connected to it). 4KV x 0.8A (Max) + The water should reach 60 degrees Celsius. @*/false; And if any arc still does destroy anything at all, it probably only will be the little Neon Bulb. Switched off mains, removed the hot vessel and brought the oven back to my workshop. document.getElementById("af-footer-413914580").className = "af-footer af-quirksMode"; This high voltage powers the magnetron to heat … In the CRT Television repair days it was possible to test the precense of the HV Transformer Output by simply holding a small Neon LightBulb near it. There is no difference in the application you intend to apply. So it was an economical and proven method suggested by my close Techie friends here! } Of course provided that mains voltage is applied to the big transformer. Albert, you will get the nominal VA power of the indidual transformer you use minus the losses. Checked and found that the oven was getting turns on and rotating but won’t or doesn’t heat up at all. • Do not pop prepackaged commercial microwave popcorn directly on the glass turntable. In addition to all above, you don't need a huge variac for the recommended (no load) test. Does it matter if you swap the connections on the 'F' and 'FA'? • Do not leave microwave … I tested my transformer by feeding 12V-AV on the primary side and got about 110V-AC on the secondary. Connect the high voltage windings with each other and then use one of the primaries as input and the other as output. The magnetron is not repairable—if the magnetron is burned out, you must replace it. Hi Parasuraman Some dirt on the caps and in some inaccessible areas was stubborn and inseparable! To enable all features please, YAF.NET © 2003-2020, Yet Another Forum.NET. I have checked the individual high voltage components (diode, … This site uses Akismet to reduce spam. Microwave ovens are not having good market here, as people have turned away to other methods like Induction Cooker etc. http://www.applianceblog.com/mainforums/threads/6623-Kenmore-665-60659000 So, if your LRM2060ST microwave not heating, runs but doesn't heat or turns on but doesn't heat … Please leave it in the comments. It only needs a small power variac. 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? one more thing to share please. I do not stock Magnetron to connect another one and test! But it was not functional! if (document.getElementById("af-body-413914580")) { So, we need to be extremely careful  in doing all these)  So carried the oven back to my workshop and removed it. This is true, but refers only to leakage test/problem. General reply to all (since I am using my mobile for reply): The defective Magnetron was not short at all! If not then th… 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. if (document.compatMode && document.compatMode == 'BackCompat') { High voltage diode helps to power the magnetron and is located in the cabinet. You can also forward this website link to your friends and colleagues-thanks! LG microwave not heating. And this depends upon its overall losses or else upon its quality as a product. (function() { Follow our troubleshooting steps to solve the problem. It is self evident that if there is a short in the windings it will cause a high current draw in the primary side, even when the Variac supplies a low input voltage to the primary. Cheers (; ). Common solutions for: LG Microwave not heating 01 - Diode The diode converts the A/C power output of the transformer to D/C, doubling the voltage to nearly 5,000 volts.
