Viking Oven won't ignite

Model: VGCC5304BSS Service Manual: https://www.manualslib.com/manual/1072350/Viking-Vgsc530.html?page=15#manual

When I turn the oven on (bake or broil) the indicator light comes on like it's going to try to heat up, but the igniters never fire.

The service manual is for three models, one of which contains two ovens. I assume that I can look at the linked page and just pay attention to the RH Oven entries.

Anyway, the options for my symptoms seem to be:

Open or shorted RTD - not sure if the same logic as thermostat applies

Open thermostat - I think I can rule this out because the indicator light wouldn't come on if it couldn't sense I was below temp

Open selector switch

Open oven control board

Open direct spark module

Defective oven wiring (shorted, open, or burned)

My thought is I should probably open it up and check the LED error codes to see if I can rule out a few more options. Does that sound reasonable?
