Rbj for Model Number JVM1871SK04 Microwave stopped heating. A couple days prior I heard some intermittent sparking when starting. Now just giving a loud humming and no heating. Would like to repair myself but concerned about getting voltage out of the unit/capacitor/magnetron before replacing part. Watched videos on YouTube and suggestions (insulated needle-nose pliers, crossing a pair of plastic handled awls while touching each capacitor connection, etc). Main question: If I leave the microwave unplugged for a couple days, will it drain all the dangerous levels of voltage out of the capacitor and take away the potential of electrical shock. Other question: Out of the three most likely problems (magnetron, capacitor, diode) which would you install first based on the symptoms? Thank you.
Answer Rbj, Leaving the unit unplugged is supposed to drain out the high voltage but better safe than sorry. Go ahead and short the capacitor with insulated pliers. Usually, you will find the magnetron is the problem. Read More... Answered by AppliancePartsPros.com | Thursday, November 30, 2023
