When try to use the microwave, it makes a loud buzzing noise and it doesn't heat. i just tried it again and let it run for 1 minute. It doesn't heat and it smelled like something was starting to melt.
The symptoms you are describing are typical of a magnetron that has gone bad. Continuing to attempt to use the oven in its current condition can cause further damage. So, I would recommend not using it. Microwave ovens are considered dangerous and repairs should not be attempted by anyone that is not electronic saavy. The High Voltage Network inside the oven has voltage potentials of 14,000 volts and higher. If you feel this is something you wish to attempt, the Magnetron part number is 1156751 and costs approx. $158. Keep in mind, if the magnetron has been arcing and making a burning smell you may have burned the protective coating that lines the walls of the waveguide. If the waveguide is damaged it is not repairable. I do not know if this is a replaceable item on your model microwave. Double check your warranty information and/or owner's manual. In many cases the magnetron is warranted for several years beyond the limited warranty that comes with most appliances. Post back with comments and let me know if you want me to assist you further. In addition, if you provide me with your EXACT model number (located along the door opening) I can narrow down parts a little better. I know this all sounds discouraging, but I do hope I have been able to help you.

Exact same problem as Crunyan's microwave, Except I have a GE JVM1640 Spacesaver. No heat, but everything else seems to work ok. It has been only 8 months since I paid a $115 for a GE service repairperson to replace an $18 part! If I can't repair it myself this time, I am just going to buy another microwave - but not a GE! Any advice?
Hi jsrock516
I have the same problem on my GE Spacemaker XL model JVM 1350.
If you think it is the Magnetron, I want to replace it myself. Is this difficult?
I'm aware of high voltafes in capacitors, and in the Magnetron itself, and will ground out them before I replace the tube.
What is the number of the Magnetron?
Thanks Gary in Hillsborough NJ
My microwave is making the same type of noise. It is a loud buzzing type of noise. Then I can smell something also. We bought it in 2000. I thought it should last longer than this.
everything is working
