Here are your parts
Replacement parts for AOCS3040SS models | AppliancePartsPros.com

I am assuming that everything looks normal just no heat.

Try the following first. The control, fan, etc. use half the line (120 volts) but the elements require the full 240 volts.
Try flipping the breaker off/on slowly a couple times.
Sometimes you can loose half the line without actually tripping the breaker.
If this does nothing, check the voltage at the plug
L1 to L2 should be 240 volts
L1 to Neutral and L2 to Neutral, both should be 120 volts.
If OK
Unplug the unit and check the wires at the terminal strip in the machine to make sure none are loose or burned out
If OK
Check the power at the terminal strip.
Do this with the heater off and on.

Many units have a thermal cut-off (fuse) in line with the elements.
The parts do show a limit kit (Item 38 in Section 2) but I do not have a wiring diagram so am not sure what this part is doing.
If it has a fuse often they blow after a long self clean cycle.

Other causes are a bad oven sensor or a sticking relay on the control board or sometimes they just blow for no apparent reason.
I will do some more searching to see if I can find a wiring diagram.
