Attached is a tech sheet. It is for a BWH2 unit but yours should be the same.

Here are the parts, also for a BWH2

Looks like a F3 E2 is an over temperature error.

Have you tried removing power from the unit for a couple minutes to see if the error/microprocessor will reset?

If this clears it then check that the fan is OK.

If this does nothing I would check the oven sensors.
Below is a link on this, take a look at 7, 8, 20 and 21.

The oven is going on 15 years old. This is the first problem we have had with it. I guess its possible that being that old you wont find anything on it. When I google the model number nothing comes up. Its the model number that is on the right side of the upper oven when you open the door.

I shoot a picture of the model number and the front of the oven itself and post it tomorrow.

Last night while using both d ovens we hear two beeps a puase then one beep and the display was dark except for error codes. There was an E2 in the middle of the display and on the extreme right side there is an F3.

I'm not quite sure how to interpret these error codes.
