The top blower/cooler on the top portion of the oven only turns on when using the lower oven. So I have replaced the blower and still the same issue. Any ideas what may be causing this from not working when upper oven is on?
Here are your parts

See the attachment for your tech sheet.
Since everything else seems to work OK it sounds like the control board is the problem.The upper oven blower relay contacts are not closing.
I would check the wiring at P24-5 to the fan just to be sure it is OK
