The KitchenAid Superba gas oven doesn't heat up to temp all the time, just some of the time (very inconsistent). Most of the time when using the oven it just stays on "Lo" and never actually heats. If it sits for 30 minutes (or so) and than try it again, it usually will work (not always). The broiler, range and display work fine. This is consistent with the ignitor not providing proper feedback to the control board, which than does not give the command to open the gas valve.
