I will check continuity. I did check for voltage across these two terminals. And same result. No 120 volts. Should it read 120 volts when operating? Where would I read the incoming 120 volts to the valve?

I looked at the gas valve parts on this site. I see two LARGE copper terminals. I assume this is the 120v in. Then it makes sense that the other 4 terminals , two on top to Broil, and two on the bottom to the bake. So I check continuity to the lower terminals. If I find very high (?), then probably a bad valve?
Can I switch the wires on top to the bottom (safely) and see if the burner or the igniter lights up?
I will take a picture and post it when I can.

Don't dig deeper than it's needed. If it reads close to "0" then the problem is a bad control board. If it reads "∞" then the gas valve has to be replaced.

 Thanks. I appreciate the help. I understand the dual valve now. It may be that the oven side is bad. I'll let you know what I find.

It measures near zero resistance across the two lower terminals leading to the bake side. Actually .001 ohms. So problem is in the control board. Probably a bad relay. I will look at the board again and check for loose wires leading down to the gas valve. What should I measure or look for to check the control board? Can I check output at the board by looking for a 120 volt output ? Are there test points I can look at on the board?
Thanks

There are a lot of numbers on the control board.
The control baord numbers are:
1005031339
RG01CXP002
183D7277P005CN
TORISAN AND TOTTORI SANYO ELECTRIC is the manufacturer names on it.
Do any of these numbers make sense?
The control board is basically 2 PC Boards mated together. On the smaller board, there are two sections marked BAKE and BROIL. There is one relay in each section. I am guessing they are independent to the different functions of broil and bake but they both have a COMMON Line wire. There is a LINE terminal (120v) going into the Board. Then in the bake section, there is a terminal (labeled BAKE) that leads down to the bake section igniter. I am guessing the relay in the bake may have gone bad. The PN on the relays are different so I am guessing one is NO and the other may be NC. They are Siemens relay, PN T7CS1D-12 (bake) AND T7CS5D-12 (broil). It happens alot for electronic relays to go bad. How Can I check the output or resistance of the control board at the bake terminal to be sure the control board is bad? ?

Check for 120 VAC between that terminal and ground while the control calls for Bake. If there is no proper voltage then the control board has gone bad. Gene. P.S. I need you to double check the model number if you need the right part number for the control board.

Checked the model number several times. I know it does not correspond to the models that come up on the parts search.
MODEL NUMBER: JGBP26WEA5WW (Yes it is a '5')
SERIAL NUMBER: VA205739P
I need to check the voltage.

I checked the voltage between the AC N terminal on the control board and the BAKE terminal. In the off position, I measure 0 voltage. Turn it to the Bake setting, I read 120 volts . So it seems the control board is operating. Somehow the voltage is not reaching the bake side of the gas valve. I am going to run thru each reading again.
I will proceed from the control board and work my way down.
What resistance should the ignitor read. Last reading was 135 ohms, Brand new.
