In this as in other inverter models, shutting off after 30 seconds (more like 20 in most cases) is usually a symptom of a bad inverter or magnetron. Due to the lethal voltages involved, I do not recommend that a person without training and experience ever work on these models. You should be able to locate a Panasonic-authorized servicer here: http://www.pasc.panasonic.com/WhereTo/FindServicer.asp?Pass=1 I would mention the exact symptom when you call so the technician can bring a new inverter and other parts with him when he comes out to repair it. Might save you having it pulled into the shop. If you or a friend insist on trying to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can order parts via Panasonic at http://www.pasc.panasonic.com/epartr

Our whirlpool microwave does not heat. Everything


Hi!if your microwave does not heat, it only means that the magnetron is not working, try to look for busted fuse. or check the capacitor for leak, the hi voltage diode sometimes malfunction, and if all of the above mentioned are all ok maybe your magnetron is defective.

Everything works except the cooking part/no heating/turntable not turning, help!


you may have gotten a power surge and that can cause some funny things to happen, 1st is there power to the oven, 2nd if so there may be an internal fuse protector built in to the oven, check with the manual for anything of that sort listed. if not you may have to take it in and have it repaired by a pro. there is a lot of voltage in these ovens and unless you know what you are doing a person could get hurt
