Buzzing Microwave GE XL1800

Unit has a buzzing noise as soon as you plug it in table doesn’t turn and vent louver won’t open on its own

Where this noise is coming from?

Gene.

from behind the control panel

Open the control panel and check all door switches.

Look for an envelope with the tech sheets behind the top grille and post it.

Here are the break down diagrams for the GE microwave Model JVM1860WD001

check cap. C01 220uf 50 volt
cap. opens allowing ac on the 24 volt dc contacts.
the noise you hear is contact chatter.

C01 cap replacement that is. Got a dozen on ******** for $8.00 free shipping.
Received them two days later. Popped it in - Works like new.

Looks like this was your only post ! ! !

You are the DJMan ! ! !

Since I stumbled across this Forum as my GE Spacemaker XL1800 is doing the exact same thing (buzzing sound, seems as if there not enough electricity) can someone point me in the direction as to where I can buy this C01 cap? As well as how to replace it since this seems to be the issue?

Thanks in advance

Hope this works for you. I was so lucky to find this post.

I got a dozen CAPs cheap on the site where you can bid for anything:cool:.
Find C1 written on the printer circuit board. You will see the size and the specs 220uf 50 volt written on the side. Using a soldering iron, heat each connection to pop each off the board. Put a new one in the same holes - make sure you get - & + wires in right holes - and re-solder.

Thanks for the info

Thank you, thank you, thank you, djman! I’m so glad I found this post. I would have been buying a new microwave otherwise. I got double-lucky and found an electronics distribution center in Springfield, OH (just a bit up the road). In a few hours I had the new cap installed and the microwave works great again!

Thanks a lot, djman!

I had the same/similar problem - buzzing sound when the door opened, or any cooking function was selected, plus the table did not turn. Replaced C01 (220uf 50 V) and the microwave works like new.

All I can is thank you. I purchased a capacitor online and replaced it in 10 minutes. Can’t believe it completely addressed this issue.

The capacitor and the burned 30k 1/4w resistor did the trick. Like new.

This must be a defect with this model board. Can’t imagine how many went into the trash b/c the board is $150 over $4.00 in parts.

FANTASTIC!!!

Same issue. Microwave started making a terrible buzzing noise. After researching online, I found this thread. Suspected capacitor C01 as djman said. Ordered the part from an online from Parts-Express, bought a cheap soldering iron kit, removed the old capacitor, and soldered in the new one. VOILA, it now works!

I hope someone else finds this useful. I have never soldered anything before and I had no issues, although I read up on it and watched a few YouTube vids first.

Cheers.
