Electrolux Refrigerator Repair in Toronto — Running constantly / never shuts off

• Before condemning any part on a 'runs all the time' Electrolux call, we rule out normal behaviour, because on the modern French-door and counter-depth EW/EI platform a long runtime can be by design rather than a fault. Electrolux's own owner literature documents that these variable-speed inverter-style compressors are built to run most of the time at varying intensity (pausing only for the defrost cycle) to hold a steady temperature efficiently, so 'it never shuts off' is not automatically a failure. We verify both compartments are actually AT setpoint and the box is sealed and recently loaded/opened before we chase a repair - condemning a healthy variable-speed system as 'running constantly' is the single most common mis-call on this symptom.
• A frost-packed evaporator from a dead defrost circuit is the number-one genuine runs-constantly fault on this platform: when the coil ices fin-to-fin, airflow chokes off and the unit runs nonstop trying to pull heat through a blanket of frost. The two cheap parts that do the melting are the defrost heater 242044113 (genuine Frigidaire/Electrolux OEM, 115V/450W; replaces 240316107 / 241940201; AP4527302 / PS2581596) and the defrost bimetal thermostat 5303918214 (clips to the coil to terminate the cycle, opens ~47F / closes ~22F; AP2150145 / PS469522). We pull the rear freezer panel, confirm the coil is frosted, then continuity-check the heater AND the thermostat before condemning anything - an open heater or a thermostat stuck open never melts the frost, so it rebuilds every cycle and the compressor never gets to rest. This is the same heat-delivery logic as the drain re-icing elsewhere on this platform.
• A failed or obstructed CONDENSER fan motor makes the compressor run continuously because rejected heat has nowhere to go - the compressor overheats, loses efficiency, and never catches up to setpoint. On the shared Frigidaire/Electrolux platform the genuine OEM condenser fan motor kit is 5303918774 (Frigidaire/Electrolux OEM; AppliancePartsPros AP6034262; PartSelect PS11766772; supersedes 240334001 / 240397101 / 240525401 / 241681101; ships as motor, blade, bracket, foam tape and screws). We confirm the blade is clear and spins freely, then meter the windings for continuity; a seized or open-winding condenser fan gets the kit, not a guess. This is distinct from the evaporator-fan SY EF fault - the condenser fan lives at the compressor end and its failure shows as a hot compressor running 100% duty rather than a freezer-cold/fridge-warm split.
• A condenser coil packed with Toronto apartment dust and pet hair is the cheapest real runs-constantly fix and the one most often skipped: as debris blankets the coil the system sheds heat poorly, the compressor cycles on more and more until it simply never stops. We brush-and-vacuum the condenser and confirm the condenser fan (kit 5303918774) spins freely with winding continuity BEFORE chasing any sealed-system or board part, because a new cooling component dropped onto a dust-blanketed coil just re-loads, overheats, and runs constantly again. On these counter-depth EI23/EW23 cabinets the coil wants a clean every 6-12 months.
• A stalled evaporator fan reads out on the door display as SY EF (System / Evaporator Fan - the board lost the freezer evaporator-fan feedback signal, fan not turning) and forces a constant-run pattern: these are single-evaporator cabinets, so when the fan quits, cold air stops circulating, the box can't reach setpoint, and the compressor runs and runs while the fresh-food side drifts warm. We spin the blade by hand, meter the windings, and check for pin back-outs or pinched leads, since the same SY EF can flag a defective board or wiring rather than the motor itself; with good wiring and no feedback the part is the evaporator fan motor kit 5303918549 (genuine Frigidaire/Electrolux OEM, 120V/60Hz/6W; AppliancePartsPros AP4700070; PartSelect PS3419839; cross-ref 241854301, verified against the full model/serial). A slug of ice from a stalled defrost can also jam the blade, so we clear any evaporator ice load first and only fit the motor if the wiring is good and there is no feedback.
• A thermistor reading false-warm pushes the board to call for cooling that never ends: the platform throws OP (a zone temp sensor read open) or SH (a zone sensor read shorted), per zone on the FF or freezer display. If the sensor tells the board the box is warmer than it really is, the board keeps the compressor running trying to satisfy a temperature it can never reach, so the unit runs constantly while the cabinet may actually be over-cold. We inspect the harness for corrosion or a pinched lead first, then ohm the sensor against its resistance curve before condemning it - an inexpensive thermistor reading false is a real runs-constantly cause that gets misdiagnosed as a board or a charge fault.
• A worn or compression-set door gasket lets humid Toronto kitchen air leak in continuously, so the evaporator ices faster than defrost can clear it and the compressor never stops fighting the infiltrating heat - common on the heavy counter-depth French doors (EI23/EW23, e.g. EW23BC85KS) and on doors left slightly ajar by a misaligned hinge. We confirm a dollar-bill seal test around the full perimeter and that the doors are square before pulling the rear panel, so we don't quote a heater or a board on what is really an air-seal or hinge-alignment path feeding a constant cooling load. Electrolux seals are model-coded, so we confirm the exact gasket by full model/serial before ordering.

Electrolux running constantly / never shuts off in Toronto — the local specifics

• The recurring Electrolux runs-constantly pattern we see across Toronto is split between two stories: a genuine fault - a frost-packed coil from a dead defrost heater/thermostat or a dust-blanketed condenser coil with a tired condenser fan letting the compressor overheat and never rest - and a healthy variable-speed unit doing exactly what it's designed to do. A real recurring observation is how often a 'it never shuts off' call on a modern EW/EI French-door turns out to be the normal long-runtime inverter behaviour, so we verify setpoint and seal before we ever quote a part.
• To these calls we bring the defrost heater 242044113, defrost bimetal thermostat 5303918214, evaporator fan motor kit 5303918549 and the condenser fan motor kit 5303918774, plus a vacuum/coil brush and a thermometer to confirm actual box temperature before condemning anything - so we can settle a frosted-coil, dusty-condenser or false-thermistor cause in one visit and tell apart a real fault from normal variable-speed runtime.
