The SEC302 is a legacy 30-inch Thermador double wall oven with independent convection/thermal cavities. As an older model, exact error code behavior isn’t part of Thermador’s current published error-code documentation, so diagnosis relies more on direct testing of the heating elements, sensors, and control board for the specific cavity affected rather than a documented code lookup.
Parts availability can take longer to confirm on a legacy model like this one — worth checking early once the actual failed part is identified.
Key Features
- 30-inch electric double wall oven (convection/thermal)
- Legacy Thermador model — still has an official Thermador service/support page under specific sub-model numbers (e.g. SEC302BS)
- Two independent oven cavities under one control system
