We have a GE Model JVM1339WW002 XL Spacemaker started to make louder buzing noise when turned on & doesn't heat

SOURCE: ge spacemaker microwave JVM1330BW002 making noise, food not warm

bad news I am afraid. the heart of the unit has had a coronary and needs a tech to intervene

SOURCE: My GE spacemaker microwave won't heat and makes an unusual sound

I have the same problem on my oven- model JVM1640WB and called an appliance repairman who is honest and reliable (I've used him before). He said the problem is with the electrode, to fix it is roughly $300. He recommended buying a new microwave rather than fixing it.

SOURCE: F3 error GE Spacemaker XL 1800: Model JVM1851CD.

F3 on a GE / Hotpoint microwave means you have a shorted membrane keypad (aka membrane switch).

If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.

So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and of course one should never leave a microwave unattended while cooking.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

If you would like to have us do this repair for you, we do that for $39.95 plus part costs nationwide.

Either way, we can let you know what your options and costs would be and send you other helpful info.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Feel free to contact me directly (and please remind me of your full model number from the tag on the unit) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.
