Good deal,
That kit retails for well over 100 bucks depending
on where you get it. I am a bit surprised they didn’t
insist that you seek out a warranty authorized service
person to get it covered. That’s because it’s standard
procedure to file warranty paperwork by the tech.
I know you already replaced the diode, but I would
make sure to replace it again with the one that comes
in the kit. Make sure you observe the proper polarity
of the diode. Let us know how you make out.

Hey Glen65, well I called GE and found out the mag. is warrentied for 10 years and mine is nine years old so they are sending me kit # wb27x10489 for free...it comes with mag,stirrer,and diode. Thanks for all your help!!! Hopefully this will fix my problem....FYI the number I called is 1-800-437-9283...At first they tried to say I had to have a GE authorized person look at it, but then they got me in touch with the right department and kit is on its way!!!!!!!

Does this mean the mag is bad for sure? It’s a bit tough to be 100% when you’re trying to fix stuff over the net. But if you’re getting a real loud humm, and you know you’re getting the high voltage to the mag that you’re supposed to be getting then the mag is no good. The excess hum is because of the fact that the secondary circuit is being loaded down more than normal. Now if you were to pull the wires off of the mag and you were to still get a loud hum then you would need to suspect one of the other secondary high voltage components. Quote:(pulled mag out and found no signs off arcing on anttenna or waveguide looks great). That doesn’t necessarily mean it’s good. Most of the bad ones I’ve ran into don’t usually show any visible signs of damage.Quote:
another thing is that I can never get a discharge out of the capacitor with a screwdriver even seconds after I run the microwave.could the mag be causing that too?
Its possible, If there is a problem with the mag it could act as a short. Dont forget there's also a bleed resistor built into the cap. Quote:
Thanks for all your advice
No problembo

No,
You may have more than one problem with the unit.
It’s possible you have a relay on the circuit board
that’s sticking in the closed (or on ) position.

I Will Try That But As To The Humming Starting By It Self As Soon As I Shut The Door Is That Normal? Thanks

A louder than usual humm most of the time is a problem in the high voltage
secondary circuit.
Put all of the primary connections back on the transformer.
Then disconnect the leads from the mag
“MAKE SHURE THEY ARE ISOLATED AND NOT TOUCHING YOU OR ANYTHING IN THE MICRWAVE CASE” then start the microwave.
If the loud humm goes away then you most likely have a bad mag.

NEED HELP....My problem started as a no heat problem (Everything worked but gave a loud humming sound and no heat) I tested the capacitor, mag, transformer, diode, interlock switches and all seemed ok except the diode seemed a little heat discolored on one end so I replaced. After replacing the diode and hooking everything back up when I closed the door a humming started.(Stops when I open door). Recheched my conections to the schematic and I do have everything hooked up correctly. Checked the interlock switches again and they check ok. So I unhooked the primary connections on the transformer and with the door closed I get about 130 volts going to the transformer as soon as the door shuts.(does this indicate a board problem?). thank you for any advice:)
