The unit still heats but the grinding noise is coming from top right.
I read some of the JVM 1600 series had some kind of defect or recall that was described exactly like the problem we are having.
this is a 2 year old over the range unit. I am hugely disappointed in this GE product. IS this a fix or a replace problem.
Quite often this is due to grease or food particles stuck to the inside of the oven or stuck on or behind the waveguide cover.
In some models it is a larger stirrer cover type made of thicker plastic in the ceiling of the oven.
It can be fragile, and the metal edges of the oven behind it can be sharp, so be careful!
The cover and the metal behind it should be cleaned with a mild, non-ammonia cleaner.
If the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean and dried thoroughly.
Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.
If your waveguide cover is burned, it will need to be replaced. It provides important protection for the magnetron.
Sometimes this problem is due to a defective magnetron or a failing stirrer.
Details of GE's recent magnetron trouble are in their bulletin here. Even if your model is not on the list, the same problem can occur, requiring a kit.
If
you or someone you know decide to look into it, we have critical
information on safety, disassembly and door switches at our site, and
our link is at our listing here on FixYa.
There
should also be a "mini-manual" hidden inside the unit behind the
control panel or hidden on the left side behind the grille, which is
very helpful when troubleshooting.
You can find helpful exploded view diagrams and order parts by entering your full model number here.
Since it's within the magnetron portion of the warranty (usually 5-9 years)
but out of the original full warranty (usually 1 year), then your
manufacturer will cover the part cost, but not the cost to visit you or
the labor charge to do the work.
Unless it's covered by this bulletin's campaign, in which case it may still be free to fix it all.
If needed, they may send you a replacement magnetron. GE Customer Service is here.

Same issue same oven. I think I have it isolated to the stirrer motor on top but don't see a way to get to it. Do I need to remove the oven? It is a hood mount or under cabinet over range.
