Thermador Wall Oven Repair in Toronto — Control panel or touchpad not working

• The signature control-panel-not-working fault on a Thermador (BSH) wall oven is a stuck-key lockout: the control reads a button as permanently held-down, beeps, and stops accepting commands so the panel looks dead even though the boards and 240V supply are fine. On this platform the code is E011 (control-panel malfunction / continuous single-key press) and, on Masterpiece J-series cavities, E032 ("Continuous pushing of keys" per the ME301J service manual). The honest first step is a power-down for 5-10 minutes, then clean the control surface and reseat the touch-panel ribbon -- a moisture- or grease-bridged contact clears on a reset roughly as often as it codes a real fault -- before we condemn the touch-panel/control assembly. On SC/SCD-generation double ovens that assembly is the genuine touchpad-and-control-panel 00368777 (stainless, fits SC301T/SC302T/SCD302T, replaces 219600 / 35-00-731) or the sibling 00368771.
• A black, unresponsive touch panel with the cooktop or another cavity still working isolates the fault to a communication break between the user-interface/display board and the electronic oven control, not the house supply. On the Thermador/Bosch platform this is the E005 / E009 pair -- 'no communication between the user interface and the electronic oven control board.' Thermador redesigned the inter-board wire harness to fix exactly this, so the replacement display control board now ships WITH a new harness. We disconnect power, reseat and inspect every plug between the display board and the control board, and replace the harness if it's heat-degraded BEFORE ordering the model/serial-coded display board -- a single loose or corroded connector triggers the same dead-panel symptom and is the cheaper find.
• A dim, partially-lit, or completely-out display traces to the main/display control board itself. On single ovens that board is 00702450 (alternates 14-38-901 / 00491431 / 492067); on the broader Masterpiece/Professional line it is 00702451 (replaces 486786 / 488797 / 492071). The documented failure set is 'oven display, clock or ERC is dim or completely out,' and once the board has power but the display won't light, the board is condemned. We prove 120V is reaching the board before quoting it, because a dead display board and a lost supply leg look identical from the front of the panel.
• The display control board and its relay board fail as a matched pair on this platform, which is why they are sold and repair-rebuilt as a kit. The relay boards are 00492069 (pairs with display board 00702450) and 00369126 (pairs with 00702451); the relay board is no longer sold separately because when it drifts out of range it shorts and takes the display board down with it. So a control panel that's gone dead alongside a heating complaint (bake/broil not firing) is a both-boards job -- we rebuild or replace the display board AND its relay board together rather than swapping one and having the survivor kill the new board.
• A control panel throwing E012 ('Defective User Interface PCB temperature sensor' per the ME301J service manual) or E014 ('ON/OFF key does not work') is a user-interface-board fault, not a main-control or oven-sensor fault: the UI board carries its own onboard temperature sensor and the power key, and either failing locks out the panel. We confirm the cavity RTD oven sensor 00414152 still reads in-spec at room temperature first -- so we don't condemn the UI board for a problem the cavity probe is actually causing -- then, with a good probe, the fault is the model/serial-coded user-interface/display board.
• An intermittently dead panel that resets itself or scrambles its display traces to a power-quality or connection fault rather than a failed board: a backed-out or corroded pin on the control board's power harness, or a heat-tired connector at the terminal block, browns out the BSH logic so the panel flickers dead and recovers. We meter each hot leg (120V per leg, 240V across the pair) reaching the control board and inspect the harness for char or a backed-out pin before condemning the 00702450/00702451 board -- on an integrated luxury oven an intermittent dead panel is a connection hunt first, a board call second.
• A panel that went dead specifically after a self-clean (pyrolytic) run is the thermal-aftermath case: the cavity overheats under clean temperatures, and the resulting sensor/door codes (E101/E104 upper or E201/E204 lower sensor open/short; E106/E206 latch-won't-lock) cascade into a locked-out, non-responsive panel. We let the oven cool fully, clear the latch and sensor faults, and re-meter the RTD 00414152 before touching the control boards, because re-powering a panel without resolving the self-clean overheat just re-locks it on the next cycle.

Thermador control panel or touchpad not working in Toronto — the local specifics

• The recurring Toronto pattern on these control-panel calls is the stuck-key lockout (E011 / E032) showing up on built-in Masterpiece and Professional wall ovens after moisture or cleaner gets behind the touch overlay -- it presents as a totally dead, unresponsive panel and clears on a power-down-and-clean far more often than it needs a board. The second recurring pattern is the E005/E009 communication break (dead display while the rest of the oven is alive) on the 00702450/00702451-board generation, which is a reseat-or-replace-the-harness job before the model-coded display board. We don't reset-and-return a panel that re-locks: a stuck-key that survives a clean keypad, or an E005/E009 that survives a reseated harness, is the real board.
• We roll to these Toronto control-panel calls with the RTD oven sensor 00414152 to clear the cavity probe before condemning any board, a BSH inter-board wire harness for the E005/E009 communication fault, alcohol and reseating tools for the touch-overlay/ribbon clean that fixes most E011/E032 stuck-key trips, and a meter to prove 120V is reaching the control board. The matched display+relay board pairs (00702450 + 00492069, 00702451 + 00369126) and the SC/SCD touch-panel assemblies (00368777 / 00368771) are confirmed against the model/serial tag and ordered or board-repaired -- never parts-cannoned -- on these integrated luxury ovens.
