HI again Franco. I found your model number. The 2 suspect components are Items 49 and 50 in this link: http://www.appliancepartspros.com/partse...



The capacitor is here http://www.appliancepartspros.com/part_d...



First of all before you do anything make SURE power is off.

Once you gain access to the capacitor "respect it"... they can still bite! While holding a screwdriver well back on the handle, short across the terminals several times to drain any residual charge. A good capacitor will POP 2 or 3 times. Once you have grounded it then use a meter on R x 1,000 or R x 10,000 and touch the 2 terminals with the 2 test leads. The meter should jump.... reverse the leads and the meter should jump again but both times return to the highest reading. / no resistance.



That brings us to the Diode:

More often than not this is the culprit that causes the hum.



Make sure one end of the diode is disconnected and then read across the diode with the meter... reverse the leads and read it again. You should only get a reading in ONE direction. If it is open in both directions the microwave will not work. If it is shorted in both directions the microwave will not work.



That is it pretty much in a nut shell. Just make sure you test components thoroughly before dashing off to the Appliance parts supply or ordering parts on line. Saves you lots of money!!!



No matter what GE is going to make sure that you spend at least $50.00 for one of the 2 parts to get you going again.



Just as a preventive measure I would change item 47 (Fuse) while you in there. The HUM that your hearing has really loaded / shortened the life of your fuse. This is either going to be a 15A or 20A fuse. You can get them mose anywhere they sell fuses. Just match up the numbers.



Thanks for using FixYa!
