Microwave-loud-buzz-not-heating, if your microwave is making a loud humming or buzzing noise, it may mean the magnetron is not working properly. the magnetron is part of the high voltage circuit that generates heat in the microwave.. If your microwave is making an unusual or loud humming noise, you may have a problem with the magnetron. this component is part of the high voltage circuit and provides the microwaves that generate the heat., the microwave does not heat and makes buzzing noise. let us consider the situation when the microwave does not heat and produces buzzing noise. 1) high voltage transformer.
Hi, my microwave stop working as it does not heat anything. it makes loud buzzing noise, light is on and the glass plate spins but no heat. anyone know if this can be fixed or will i have to get a new microwave... thanks, steve, view this repair: http://www.appliancevideo.com/kitchenaid-khms155lbt0-microwave-diagnostic-repair-will-not-heat-loud-noise-when-running/ visit us at http://.... If your microwave is making a loud humming noise, first check to see if it still heats efficiently. often, the humming noise is associated with a microwave malfunction., my ge profile spacemaker 2.0 started to hum a bit louder and now makes no heat. i followed the ge troubleshooting flow-chart and it points to the magnetron, but the resistance checks (continuity pin-to-pin, open pins-to-case & no sign of any arcing or cracks in magnets)..
Microwave ovens generate high voltages (thousands of volts) and dangerous amounts of radio-frequency radiation. attempting to repair one is not for the amateur tinkerer. i advise recycling or trashing it and getting a new one (they don't cost much these days.) - ge microwave oven
