Thermador Stove Repair in Toronto — Electric element not heating

• On a Thermador dual-fuel range (gas star-burner top over an ELECTRIC oven) the no-heat symptom lives in the oven cavity, not the cooktop. The signature failed part is bottom bake element 00367648 - the bake element fitted to BSH/Bosch 30-inch ovens (~22-inch element span, located at the bottom of the cavity), which supersedes/replaces 1028908 (and 14-38-443); the longer-span element used in other cavities is 00367649. A good element glows fully red and reads continuity on a multimeter; a black, non-glowing element with an open (OL) reading is condemned and swapped, a 10-20 minute job once access is gained. We rule the element out by measurement before ever touching a board.
• Relay control board 00492069 is the documented control-side cause of 'oven does not reach temperature' on Thermador (BSH) ranges and wall ovens - a relay that no longer cycles the bake/broil/convection elements cleanly. It pairs with display/control board 00702450 (or 00702451 on some model tags - confirm against the unit's model/serial), and the failure set ('won't reach temp', 'overshoots set point', 'won't turn off') is classic for this board. We probe for AC voltage at the element terminals during a bake call: voltage present + dead element = element; no voltage to a good element = relay board 00492069.
• Oven temperature sensor 00414152 feeds the control the cavity temperature; drift, an open, or a short stops the board closing the loop, so the oven undershoots or never drives the elements. This is a platinum RTD (PTC-type) resistance probe - its resistance RISES as the oven heats - and it should read about 1080 ohms at 70F, so an OL or far-off reading at room temperature confirms it. 00627375 is a separate genuine Thermador/Bosch oven sensor used on different model tags - it is NOT a drop-in equivalent of 00414152, so the correct OEM number is confirmed against the unit's model/serial before ordering (00414152 is also discontinued on certain models).
• Error codes E101 (upper-oven sensor open circuit) and E104 (upper-oven sensor short circuit) are real BSH/Thermador range and wall-oven fault codes pointing straight at the temperature-sensor path - not at the element. The fix sequence is documented: power down, inspect/repair the sensor harness, meter the probe (about 1080 ohms at 70F on this RTD-type sensor), replace sensor 00414152 if out of spec, and only replace the electronic control board if a known-good probe still codes. Grease contamination at the sensor tip and connector is a frequent, recoverable cause we clean and re-meter first.
• A blown oven thermal fuse is a common no-heat aftermath of the self-clean (pyrolytic) cycle on Thermador ranges - the fuse opens on over-temperature and interrupts power to the heating elements; once blown it does not reset and must be replaced (e.g. behind the rear panel on RDF30Q-era cavities). We test it for continuity before condemning element or board, because an open thermal fuse mimics a dead bake element while the element itself is fine.
• Convection-mode shortfall is a separate heat path from bake: on fan-equipped Professional/Masterpiece-style Thermador ranges the convection element runs through its own dedicated relay channel on board 00492069, so an oven that bakes correctly but won't come up to temp in convection points at the convection element or that relay channel - not the bake element. Each heat circuit (bake / broil / convection) is verified independently so the right part is ordered the first time.
• Because the cooktop is gas, a 'nothing heats' call on a Thermador dual-fuel range is first triaged to confirm it is the electric OVEN, not the star burners (igniter/spark faults are the gas-side complaint). On the oven side the honest order of elimination is: thermal fuse continuity -> bake element 00367648 continuity and glow -> sensor 00414152 resistance (RTD-type, ~1080 ohms at 70F) and E101/E104 codes -> relay board 00492069 with display board 00702450 (or 00702451 on some model tags) - measurement at each stage before any luxury-priced board is replaced.

Thermador electric element not heating in Toronto — the local specifics

• The recurring Toronto pattern on Thermador dual-fuel ranges is the homeowner who reports 'the oven won't heat but the burners are fine' - because the gas star-burner top and the electric oven are two different systems, and the no-heat almost always lives in the oven cavity. A second recurring pattern follows a self-clean cycle: the oven goes dead afterward and the cause is a blown thermal fuse or a tired bake element, not the expensive control board the owner fears.
• We bring the BSH oven heat kit to these Toronto calls: bake element 00367648 (with the longer-span 00367649 as backup) and an oven thermal fuse, plus a multimeter to confirm continuity/resistance and read E101/E104 sensor codes on site. Temperature sensor 00414152 and the separate 00627375 are confirmed against the model/serial first (they are not interchangeable) so we order the correct one. Relay board 00492069 and display boards 00702450/00702451 are diagnosed and quoted on the visit, then dealer-ordered through the BSH channel so we don't guess-swap a luxury-priced board.
