Igniter glows, oven won't light

I removed the cover over the flame diffuser, then removed the single nut holding the diffuser to the burner assembly. After removing the three screws from the igniter assembly I found I couldn't reach the connector for the igniter.
I removed the storage tray underneath and found a cover towards the rear of the oven with two screws. After removing this piece I could easily disconnect the igniter. It was a bit difficult replacing this shield as it had to fit between two other pieces on the side towards the front of the oven.
I slid the guard from the old igniter and put it on the new piece and just reversed the procedure. Relatively easy and saved me a bundle!
