GE Microwave strats, runs, but not heating and have bad odor
I have a JE1540WW01 build in Microwave from GE and it suddenly lost its heating function and giving out a bad odor. Can anyone help me narrow down to which part is bad. I have check the fuse on the wall it is fine, the power transformer is fine. But I am not sure if it is the Magnetron or the heat sensor on the magnetron? Why is there a bad "electric odor"? On the manual, it said that it must ensure the RF gasket is install properly, properly sounds too vague, do you guys know how to properly install the magnetron if I have to replace one? Thanks.

There should be 4 screws holding it in.. and one plastic connector with 2 wires in it that are plugged onto the mag.. the seal would be the gold colored mesh around the antenna of the mag. when you take the microwave down you would take the cover off and if looking at it from the back you would look towards the right side and there should be a thermostat there that may have started to burn up. if it is replace it and the wires.. the mag you just unscrew remove and install the new mag.

If the fan has been running more frequently it means more heat is generated from the range and the microwave must work harder to get rid of the heat, yes it probably contributed to the failure of the device and you must decide if the item is worth repairing. It is better to run it seperately to reduce heat build up if possible.
Q - The microwave makes a loud "hum or buzz" noise but will not heat up the food? A - 9 times out of 10 this is usually this is a bad magnetron, the other time is sometimes a bad high voltage diode. See components section. Q - My microwave is running and sounds like it is working but will not heat up anything. A - Many thing can do this but, common things are....loose high voltage wire.....poor solder joint on board.....magnetron.....power relay..... Q - The microwave display counts down and the inside light is on, but nothing is heating and the fan is not running. A - This most commonly is abad door switch, other possible problems are a faulty relay or solder joint on the power module, but a bad door switch is most common. Q - The fan in my microwave oven is not running will this hurt my microwave? A - YES, the fan cools the magnetron and electronics, take the microwave in for service, most fans are not too expensive to replace. Q - My microwave blows the fuse inside itself as soon as I push the start button. A - Usually a shorted high voltage capacitor...see components section.
I had same problem last week. My GE JVM1650 Spacemaker stopped after a few seconds of heating. Owned 16 months, manufactured Jan 2005. It was the magnetron, which was replaced yesterday. The magnetron has a 10-year warranty, but I had to pay $161.00 for labor by a GE technician. The call-out fee was waived at my request. I don't know what that amount would have been, but I can't believe the $161.00 for what was about 1/2 hour labor once diagnosed. Good Luck!
