My GE Spacemaker XL 1800 makes a noticeable rattling sound when oven is running. It is not normal. Sounds like it may be in the tray drive; just guessing.

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and
disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

You can usually find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

There should be a very helpful "mini-manual" hidden inside the unit behind the control panel.

if there is no plate to unscrew in front of the bulb , then the only way it can be changed is to open the microwave

I had the same problem. I removed the grill and opened the control panel as I read an answer from "GENE" on APP (Appliance Pros) that this indicated a short in the circuit board (TouchPad). I was going to replace the faulty circuit board but when I opened the control panel there it was......One wire harness had just came unplugged!! I plugged it in, reassembled and the microwave works again!

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.
