This is a free-standing gas range/oven. The range burners all work, but today the oven won’t do anything (bake or broil). I need some guidance to figure out where to start. Thermostat? Safety Valve? Igniter? 
Any guidance will be greatly appreciated!!
when you turn on the bake does the glow bar glow? same with the broil? let’s start there

No. Nothing happens. Turned to bake = nothing; Turned to broil = nothing. 
Take a ohms reading of the glowbar, the wire ends will be behind the bottom drawer at the safety valve, post results
Yes, you are right. The igniter is bad and has to be replaced.

Guys, thanks for the help; ignitor is in and oven is working 
When the drum starts to turn there is a squeeling noise from the
front of the drum. If i reach inside i can move the drum up and down.
What supports the frontof the drum?
