You probably have a bad thermistor.
You can usually find
helpful exploded view diagrams and order parts by entering your full
model number here.
(At that site, that part is misspelled as "thermister" for your model).
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 & testing.
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.
Accessing some components for testing will require you to remove the oven from the wall.
If
so, the installation instructions are very handy, and it's best to have
two people since the microwave can be heavy and awkward.
You can download GE
owner's manuals and installation instructions here.
