I’m having an intermittent problem on initial startup. The oven will successfully ignite on the first attempt, but will continue to click 3 more times and then the gas valve will shut off.

I have replaced the electrode/ignitor, temperature sensor, and thermal fuse. The electrode was definitely well-worn/damaged before I replaced it,

Sometimes it works on the first attempt, sometimes it takes many attempts to stay lit. Once the oven is going, it seems to have no problem relighting and staying lit to keep temperature so it's really an issue on initial startup only. Broil appears to work fine even when oven won't work.

I am thinking to try the spark module next as this is DSI and I’ve read the flame safety circuit is part of the spark module. But it's an expensive part. I also read about other, not quite the same problems, where it was mentioned possible grounding issues or a pinched wire. Any ideas for where to focus efforts next? Thanks in advance.

I cleaned all the mating surfaces where the bake igniter/electrode mounts as well as the screws. Found a piece of scrap 12AWG wire and ran the extra grounding wire. I’ve just tested it out a handful of times and it’s staying lit every time… Fingers crossed this was it, that would be awesome. Thanks again for the guidance.
