Frigidaire wall oven, bake element not working

The bake element does not come on, only the upper element comes on. I metered the bake element and it looks good about 24 ohms. Any suggestions as to what the problem could be or common areas of failure? It is a Frigidaire Galaxy series model # CGEB27S7CS1.

Here is the wiring diagram

Could be the bake/convection relay.
I think is is item 112 in section 03 of the parts but am not sure about this so check the wiring colors.
Unplug the unit and check the C to NC contacts. They should be 0 ohms.

Check the wiring to/from the bake element for continuity.

If all OK then odds are that the control board is bad.

I am assuming that the unit stays in preheat or takes a long time to come to ready.

Thanks for the response denman. Yes it is as you suggest.. stays in preheat for a long time before getting to temperature and bake element never comes on, only upper broil element. To meter the bake convection relay, do I measure between contacts 7 and 8? Are those the C and NC contacts? At back of oven, orange wire connects to 7 and red to 8. wires to bake element also have good continuity.. no continuity between contacts 7 and 8 on relay. only continuity between 6 and 2 as internal contact is being pushed against 2 and away from 4 by solenoid.

Sorry but I do not have a cross refrence on which pin is which.

Using the wiring diagram.
red goes to one side of the relay coil
orange goes to the othet side of the relay coil.

yellow is C (common)
black is NC (normally closed)
Brown is NO (normally open)
