glow bar would light but oven would not light

I removed the rear access panel on the oven in order to get to the igniter wires. While testing the output voltage of the old igniter when on, I found that it was producing less than 3 volts ac. This was my clue that although the igniter glowed, it was going bad and needed to be replaced. I unpluged the oven, shut off the gas feed to the oven then removed the oven bottom pan (pull two push pins back, lift up and out) and removed the burner baffle wing nut with baffle. This gave easy access to the igniter and it's two mounting screws which i removed using a phillips screw driver. I unpluged the old igniter from the connector, pluged in the new one after routing it through the access hole from inside the oven to the back of the oven where the connector is located.
Mounted the new igniter, replaced the burner baffle, baffle nut, oven bottom, rear access panel cover, checked and turned on the gas, plugged the oven back in and sure enough it fired up right away. if you check the system of how your oven works and find the problem, it's easy to fix it yourself and save serious money...and look like a hero to the rest of the family.
