Gregg K for Model Number JE2160 Hello: My microwave stopped heating in May, I distinctly noticed that it wasn't making the deep humming/buzzing noise that it usually made. I bought a magnetron, and a couple of days later a diode and a capacitor. I installed the magnetron, and the microwave worked, so I didn't install the diode or capacitor then. Over Thanksgiving, the microwave stopped heating again. This time I replaced the diode and capacitor, and put everything back together. It still did not heat, but after a few tries, and using the "Express" setting for 4 minutes, we heated a cup of water. Thinking it was fixed, I put it back in the cabinet. It did not heat. I took it back out, and checked the magnetron, the diode, and the capacitor to the extent I could (with an ohmmeter). All seems to be okay. I suspected a switch, and was getting ready to order the primary switch, but I noticed that the magnetron was warm to the touch, and the cooling fins were hot, so despite the fact that water wasn't being heated, it looks like the magnetron is getting power, which makes me think it's not a switch. Here is my post on the forum on the subject. Do y'all have any ideas? http://forum.appliancepartspros.com/microwave-repair/507764-microwave-wont-heat.html Thanks, Gregg
Answer Hello Gregg. Based ont eh information you provided, if the magnetron, diode, and capacitor are new, and it finally heated the water, you will need to order and replace the H.V. Transformer on the unit. Read More... Answered by AppliancePartsPros.com | Thursday, November 29, 2012
