Although the ignitors glowed brilliant yellow I learned from an expert there are 2 fail modes. 1. that they break and don't glow well enough to ignite the gas or 2. they get resistive over the years and do not pass enough current to open the valve. This is important to know because the current passes through the ignitor before it gets to the valve. If the ignitor resists too much then the valve never gets enough power to open. As evidence you get slow ignitions until one day it stops altogether.

There are 2 ignitors in this oven. one for the broiler and 1 for the oven. The broiler is exposed so easily removed. For the oven you need to remove the flame spreader cover and the flame spreader. Need a good screw driver for all the screws in the oven because they get corroded from the hostile environment and also the factory torques them in pretty good when new. It is hard to get leverage leaning into an oven without leaning on the oven door which could unhinge it. With a good screw driver and getting a good seat into the screw you can break it loose. Then some muscle power to get it out. 1 screw refused to come out all the way so I grabbed it with some pliers and pulled and twisted it out. A trick I learned from my days as a mechanic is to use valve lapping compound on the screw driver. The diamond dust bites into the screw for a grip on those really bad ones.

The last tricky part is you have to remove the back cover on the oven, unplug the wires and pull the ignitor out through the oven. When you see the wires in the back you will see insulation packing.
Hint: If your smart you will tie a string to the wires before you pull it though so it is easier to pull the new ignitor wires back the same way. Else you need to use a stick to feel your way through the insulation packing to find the wires.

Hardest part of this job is undoing the screws. The rest is easy.
