Question about Maytag CWG3100A Gas Single Oven
Maytag gas oven CWG3100AAE. Glow bar glows and has 2 VAC from white to red terminal on valve. 3 VAC from red terminal to ground. Valve will open if hit with a wrench but when needing turn back on will not unless struck again.
The problem is not fixed, but I know it involves replacing the ignitor and/or the gas valve. I just wanted help diagnosing the two so I only had to buy one part if I could. We live on a budget and if I could avoid replacing an unnecessary part that would help. I am afraid your elite people would just tell me to start with the ignitor and then the valve.
Thank you just the same.

oven control supplies voltage to the oven igniter/gas valve circuit. When the
oven control is set to Bake, voltage is supplied to the oven igniter which
should glow bright red to almost white hot. Once the igniter comes on and
begins to glow it must pull enough current to cause the gas valve to open so
the burner can ignite from the igniter. I added an image below with the theory
of operation. Click this link:--http://media.fotki.com/1_p,swbbsqrsgstsqkkxgtqsskgwtqkq,vi/wrgtsbrktxwdfwfbgdg/1/1303472/5961857/image5576034710104836299img-or.png
the broiler drawer and then set the oven control to bake and watch to see if
the glow bar igniter glows or not. If it does not glow, the failure could be a
broken Igniter, failed oven control board or gas valve. If the igniter is
glowing red, then it can be possible that gas valve is faulty. To see how
igniter looks. See the fig below:--

Also to confirm, check to see if the igniter is getting 120 volts
when it's turned on. If it gets 120 volts, then your safety gas valve is bad
because it's not letting the neutral go through. Otherwise, if it's NOT getting
120 volts, your control board shorted out and you need a new control board.
But as you mentioned that control board is replaced. So igniter should get 120 volts. If valve is faulty. But if igniter is not glowing then its faulty igniter confirmed.

In most of the cases the igniter is faulty, because gas
valve getting faulty is very rare. But still getting the voltages checked, will
confirm. These will help. Thanks. Helpmech.
