Thermador Refrigerator Repair in Toronto — Ice maker not working

• On a Thermador Freedom column or built-in bottom-freezer, a dead ice maker often shows the customer-facing E2 code, but E2 is a generic top-level code with several possible causes rather than one specific fault. On this BSH platform it most often points to a freezer-section temperature-sensor (NTC) problem: if the control doesn't see the compartment cold enough it won't open the water valve, so the mold never fills and the maker looks dead even though the ice maker itself is fine. We power down 5 minutes to clear it, then enter diagnostic mode to read the specific four-digit Exxxx fault (for example E2032 ejector-motor/switch or E2025 ice-flap-motor/switch) and reseat the ice-maker and dispenser harnesses before condemning any module — a sensor or comms-path fault mimics a dead ice maker and is the cheaper find.
• When the ice maker is electrically alive but won't fill, the dual-coil water inlet valve (12028324, the genuine Bosch double 115V 'Valve-magnet water valve', replaces AP6894067) is a prime suspect: one coil feeds the ice mold, the other the dispenser, so a failed ice-side coil kills cubes while the dispenser water still runs. We meter the valve for continuity and confirm at least 20 psi of supply pressure at the valve — below 20 psi the valve won't open fully and the mold underfills, which reads as 'dead' even with a good valve.
• A frozen fill tube is the classic 'ice maker stopped overnight' on Thermador/Bosch built-ins: weak fill (low house pressure or a tired ice-side valve coil) leaves residual water that re-freezes in the tube and dams the next fill, so the maker cycles into an empty mold. These units carry a small fill-tube line heater to fight this, but it can't keep up when intake is already weak. We thaw the tube to restore flow, then chase the root cause — supply pressure and the inlet valve (12028324) — rather than just melting and leaving.
• A clogged UltraClarity Pro filter (REPLFLTR55 = Bosch BORPLFTR55 / BORPLFTR50, genuine OEM 11032531) can stop ice entirely: when the filter restricts flow it starves the mold so the maker cycles into an under-filled or empty tray and reads as dead, and the unit raises the replacement-filter light. We always rule out an overdue or aftermarket filter (replace every ~6 months) before touching the valve or mold — it's the single cheapest cause of a 'dead' Thermador ice maker.
• If fill, valve, filter and pressure all check out, the ice-maker assembly itself is condemned — 11036056 (genuine Bosch/Thermador, 9-cube 110V; replaces AP6991261 / PS16221894 / EAP16221894, production # 8001113484 / EG-320313.1). This is the module distributors list as resolving the 'ice maker inoperable' E2 condition when its internal ejector motor, mold thermostat or harness fails. We confirm the mold isn't simply ice-bound and that 110V reaches the module before ordering, since it's a model-coded swap.
• A freezer running too warm masquerades as a dead ice maker: a Thermador won't make ice well much above ~10°F and needs roughly 0–5°F to cycle, so a single-evaporator column losing cold (a frosted coil, or a faulty evaporator/freezer-section NTC, part 11030589) starves the mold long before cooling complaints surface. We verify actual freezer temperature with a meter rather than binding a specific E-code to the sensor without a model-specific service source — fix the cold first, and on a fresh install allow ~24h to first ice and ~72h to full production.
• Ice that makes but clumps and won't dispense is a distinct, dead-feeling fault: cubes fuse in the bucket (slow turnover from a marginal mold or a warm-cycling freezer) and jam the auger/chute, so the dispenser does nothing and the customer reports 'no ice.' We clear the bucket and chute, check the auger and drive coupler for cracks, and — critically — separate this from a true production failure, because the fix is bucket/auger work, not a valve or mold (11036056) swap.

Thermador ice maker not working in Toronto — the local specifics

• The recurring Thermador-in-Toronto pattern for a dead ice maker is a stacked one: an overdue or aftermarket UltraClarity Pro filter restricting flow, low winter supply pressure (below the 20 psi the valve needs), and a fill tube that has re-frozen — so the maker is mechanically fine but starved. Reading the diagnostic-mode Exxxx code and reseating the ice-maker/dispenser harness on Freedom columns before condemning a module is the other repeat we see; outright mold replacement (11036056) is the minority outcome once filter, pressure and valve are ruled out.
• We roll to these calls with the UltraClarity Pro filter (REPLFLTR55), the dual-coil inlet valve (12028324), a water-pressure gauge and meter, and fill-tube thaw gear — the parts and tools that close most Toronto ice-maker-dead Thermador visits first trip. The ice-maker assembly (11036056) and any model-coded display/dispenser module are confirmed by model/serial and brought on the planned return.
