Oven Will Not Heat

Replaced Igniter
Replaced Oven Control
Gas Control Valve Checked Ohms OK

What else can I do to get igniter working?

Assuming that the ignitor doesn’t glow, check for continuity through the ignitor. If it tests ok, check for voltage to the ignitor. If there is no voltage, trace it back, you’ll find the bad part.
If the ignitor does glow, it still could be a bad one. It needs to pass a certain amount of current to signal the gas valve to open.
Good Luck!
