Maytag Refrigerator Repair in Toronto — Ice maker not working

• Diagnose before you condemn on a Maytag (MFI/MFF/MFX, Whirlpool platform underneath): the modular head is the WPW10300024 / W10300024 8-cube ice maker (AP6019087 / PS11752391), and Whirlpool/Maytag built a self-test into it. On bail-arm heads push the wire feeler arm down three times within 15 seconds; on push-button heads press the on/off button three times within 15 seconds, and the module runs a full ~3-minute harvest. If it cycles and fills, the head is good and the fault is upstream (water, freezer temp, filter); if it does nothing, the head/module is the dead part. We run the self-test FIRST so we are not throwing a $100+ ice maker at a no-water problem.
• A freezer running too warm is the most-missed 'dead ice maker' on this platform and it is NOT an ice-maker part: the Whirlpool modular head will not initiate a harvest cycle until the ice mold drops cold, and a freezer above about 10F never lets the mold thermostat close. We confirm the freezer is holding 0-5F with a calibrated thermometer before condemning anything, because a Maytag with a frosted evaporator or stalled freezer fan (the not-cooling parts book - WPW10189703 evaporator/freezer fan, WPW10225581 defrost thermostat, WP12729128 defrost heater) presents as a dead ice maker while every ice part is healthy. Fix the cold first, the ice follows.
• No-fill, where the head runs and the rake turns but the mold stays empty, traces most often to the ice-maker water inlet valve W10498976 (WPW10498976; AP6022334 / PS11755667; replaces W10420082 / W10498974 / 2315576), the 120V/35W solenoid valve on the MFF/WRF/MBF families. With line pressure confirmed and 120V at the ice-maker solenoid terminal during the fill window, a coil that meters open or shorted is the failed part. We ohm the solenoid against its marked spec rather than assume a number, and this is one of the most common dead-ice verdicts because the valve is cheap and stocked.
• A clogged or wrongly seated EveryDrop Filter 4 (EDR4RXD1, replaces UKF8001) is the quietest dead-ice cause and the one we rule out before any electrical part: past its 6-month / 200-gallon life the cartridge restricts flow so the mold under-fills or never fills, and ice dies even with a healthy valve and head. Maytag's own literature notes that a filter not pushed in and locked fully will stop water entirely. We fit a fresh EDR4RXD1 (or the bypass plug to prove flow) and confirm fill volume returns before quoting anything bigger.
• A frozen fill tube is the signature seasonal Maytag no-ice pattern: the fill cup/tube ices over, water backs up or dribbles, and the mold stops filling even though the valve is good. The tube relies on a small fill-tube heater (a separate, model-specific part - not the defrost heater) to stay just-warm; when that heater fails, or low inlet pressure lets water linger and freeze, the tube plugs. We thaw the tube and confirm a clean fill, then check whether the heater is energizing - a Maytag that re-ices the fill tube within weeks is a heater/airflow problem, not a repeat valve swap.
• On in-door ice makers (ice bin in the French door), 'no ice / won't stop / wrong fill' with the head testing fine points at the dual optic boards, not the module: the emitter/receiver pair (kit 4389102, replaces W10757851 / 2198586; AP5956767 / PS557945) uses an infrared beam to sense bin level, and a fouled or failed board mis-reads the bin as always-full so the maker never runs. We confirm the head harvests in self-test, then check the optic emitter and receiver before condemning the assembly.
• Ice gets made but won't drop or dispense is a harvest/auger-drive fault, not a no-fill: with the head proven good in self-test, we pull the bin, turn the auger by hand (it should spin freely against the dispenser drive), then meter the auger motor W11202789 (genuine Whirlpool, fits Maytag/KitchenAid/Jenn-Air/Amana; replaces W10225313 / WPW10225313 / 4591223; AP6327333 / PS12349163). No continuity, or 120V present with no rotation, makes the auger motor the part. We separate this from a true no-ice-made fault on the first visit so we do not throw a water valve at a delivery problem.

Maytag ice maker not working in Toronto — the local specifics

• The recurring Maytag-in-Toronto ice-maker-dead pattern is the false dead maker: the call books as 'no ice,' but on arrival the freezer is running warm (frosted evaporator or a stalled freezer fan) so the Whirlpool modular head never reaches harvest temperature, and every ice part is actually fine. The other steady runner is a no-fill that's really a tired EveryDrop filter or a saddle-tap supply at low pressure, not the valve. We lead with the head self-test and a freezer-temp and line-pressure check so we fix the real cause instead of swapping an ice maker that was never broken.
• We carry to these Toronto calls: the W10498976 ice-maker inlet valve, a fresh EDR4RXD1 filter, the 4389102 emitter/receiver optic-board kit, and the WPW10300024 / W10300024 modular ice-maker head (AP6019087 / PS11752391; superseded by the W10882923 assembly kit on some serials) - plus the W11202789 auger motor when the complaint is 'ice made but won't dispense.' A calibrated freezer thermometer and a line-pressure check ride along so we can prove a too-warm freezer or a starved water line before condemning any ice part.
