Oven wouldn't heat

Replace the dual gas valve assembly for both the broiler and oven by removing the lower drawer. Then removing the drawer's right side sliding bar, and turning off the gas at the input to the valve assembly (a small part between the valve assembly and the inlet gas tube). Then unscrew the two outlet gas tubes and the gas inlet shut off assemble. Then remove the holding brackets to remove the valve assembly. I found that when the new gas valve was replaced, if the oven still does not turn on, you have to adjust the gas outletto the oven by using an allen wrench inserted into the opening of the outlet valve of the valve assembly. It has to be done several times at small incremental turns (about a 1/4 turn at a time) to get the right amount of gas flow and have it completely shut off when the oven is turned off. I found this out by taking the old valve apart of see how it works.
