Bosch Refrigerator Repair in Toronto — Ice maker not working

• Dead freezer-mounted ice maker is the most common ice-maker-dead call on the newer counter-depth fleet (B22CT/B36CT 800-series and the bottom-mounts): the modern Bosch ice maker is an 8-cube, shut-off-arm-controlled module that bolts to the LEFT freezer wall, OEM part 00798555 (genuine Bosch; supersedes 00798783 / 00798560 / 4163432, PartSelect ID PS10058636). The unit's mold heater, motor or thermostat fails and the maker stops cycling entirely. Order note that bites in the field: 00798555 ships WITHOUT the wiring harness — the icemaker harness is a separate part (PS10058358) — so confirm whether the existing harness is reusable before quoting, or the job stalls on a missing connector.
• Older Bosch Evolution side-by-side units (B20CS / B22CS30/50/80 line) use the earlier ice maker assembly 00649288 (cross-references 497877 / 497878 / AP4434733), a genuine Bosch OEM part that still orders new through standard distribution. When this maker is genuinely dead on those cabinets, confirm the full model/serial and order 00649288 against it — stock can be thinner on the shelf than the newer 00798555, so we pre-confirm distributor availability before booking rather than carrying it blind.
• Ice maker quits but water dispenses fine = classic Bosch infrared ice-LEVEL control fault, not a dead maker. The Evolution side-by-side line uses an optical bin-level system: an emitter board on the hinge side pulses IR across to a receiver board (phototransistor) on the mullion side, and the control only energizes a harvest relay when the beam is seen. Ice frosting the optics, or a failed emitter/receiver board, gives a false 'bin full' so the maker correctly refuses to cycle. Diagnose by clearing/drying the lenses and bench-checking the boards before condemning the ice maker itself — swapping a $100+ maker here fixes nothing.
• No water reaching the maker is the inlet-valve pattern: Bosch refrigerator water valves (genuine OEM 00615235, 00631861, or the magnet-style 12028324 depending on platform) need at least ~20 psi to shut off cleanly and a clear inlet screen to fill the tray. A valve that's electrically open but mechanically stuck, or a debris-clogged screen, leaves the maker dry while the dispenser may still trickle. Confirm 120V at the valve terminals on a harvest call AND adequate supply pressure before replacing — a dead valve and a starved water line look identical at the maker.
• Frozen fill tube is the Toronto-winter signature for a Bosch ice-maker-dead complaint: low supply pressure or a weak inlet valve lets the last fill freeze solid in the fill tube behind the maker, so the next cycle finds no water path and the maker appears dead. Thaw and clear the tube to confirm, then fix the root cause (pressure or the inlet valve above) — re-icing within days means you treated the symptom, not the valve.
• Freezer not cold enough is the diagnosis that prevents a wrong parts swap: the Bosch maker will not cycle a harvest if the freezer compartment is warmer than roughly 10°F (target is 0-5°F). A drifting freezer from a stalled evaporator fan (OEM 00672636), a frosted coil from a dead defrost circuit (defrost heater 12023292 / evaporator sensor 11030589), or a stuck damper presents as 'ice maker dead' — but the real fault is the cooling side, and the maker is fine. Read the freezer temp before touching the ice maker.
• Clogged water filter starving the maker: a long-overdue Bosch UltraClarity Pro filter (cartridge 11032531, multipack 11050659; interchangeable cross-references BORPLFTR50 / BORPLFTR55 / REPLFLTR55) restricts flow enough to under-fill or stop the tray, and on some Bosch platforms a missing or wrong filter cartridge stops dispense and ice outright. Swap to a genuine cartridge and purge air before chasing valve or maker parts — the cheapest real fix on this symptom, and the one most often skipped.

Bosch ice maker not working in Toronto — the local specifics

• The recurring Bosch-in-Toronto pattern on ice-maker-dead calls is the split between a genuinely failed maker and a false 'bin full': on the newer counter-depth 800-series we mostly find the freezer-wall maker (00798555) or its harness, while on older Evolution side-by-sides the complaint is usually the infrared ice-level optics or a frozen fill tube rather than a dead maker at all. We see freezer-temp and clogged-filter root causes masquerade as 'dead ice maker' often enough that we verify freezer temp and filter age before quoting any maker part.
• We roll these calls with a genuine Bosch UltraClarity Pro filter (BORPLFTR50 / REPLFLTR55), a multimeter for valve-terminal and IR-board testing, and a freezer thermometer; the 00798555 ice maker and matching inlet valve (00615235 / 00631861 / 12028324) are confirmed-and-ordered against the unit's model/serial before the visit rather than carried blind, since the BSH catalogue is model-coded — and the legacy 00649288 maker for older Evolution cabinets is likewise confirmed against model/serial before booking.
