My oven won't light

I have a Caloric gas stove. The oven won’t light. The glow thing in the back comes on but it won’t ignite. :frowning: What could be the problem?

The igniter may be weak. Here’s a replacement part.

I have a caloric stove (more than 15yrs old) the bake or broil want lite, I have new igniters on both, but it seem like there is no power to select switch or thermostat. the broil never glowed before changing both, the bake glowed barely.:mad:
