I tried searching for this, but didn't see an exact match (and pretty much zero experience with gas appliances).
We have a Viking 30" 4 burner range, in use for only 8 months, VGIC5304BSS. 4 burners on the stove work perfectly. We started noticing that the oven would get up to temperature and then sometimes stop heating. Turning the oven off for a few minutes and then back on seemed to cure the issue and it would go back to heating normally.
Tonight it worked for a bit, stopped heating, and now when I turn the knob from off to any temperature or broil nothing happens; no gas smell, no click of the igniter, nothing.
Help would be much appreciated.
