GE Refrigerator Repair in Toronto — Freezer cold but fridge warm

• The single most GE-specific cause of a cold freezer with a warm fresh-food side is the air damper, not a fan or a sealed-system fault. GE's damper control assembly WR49X10091 (AP3775595) channels cold air from the freezer evaporator forward into the fresh-food compartment; the classic GE failure is the flapper freezing in the closed position or the plastic baffle breaking off its motor, so the freezer holds while almost no cold air reaches the fridge. Per GE diagnostic literature the prime suspects on this exact symptom are, in order, (1) the damper and (2) the thermistors -- so we actuate the damper in service/diagnostic mode and listen for it to open and close before touching anything else; a damper that won't cycle, or one iced shut from a nearby defrost/door-seal problem, is the WR49X10091.
• When the damper checks good, the next GE part for fridge-warm/freezer-cold is the fresh-food evaporator fan motor WR60X26866 -- and it is specifically the FRESH FOOD fan, not the freezer fan. This DC motor (roughly 13.6VDC, 0.16A) pulls cold air off the coil and pushes it into the fresh-food section, so a seized or open-winding motor lets the freezer keep holding while the fridge drifts into the 50s. WR60X26866 is the current OEM form that supersedes WR60X26033 and the older WR60X10341 / WR60X10356 / WR60X10357. We unplug and spin the blade by hand and run it on applied DC before condemning it, because a frost-jammed blade and a dead motor present identically and only one needs a part.
• On older GE/Hotpoint platforms the same warm-fridge fault is the earlier fresh-food DC evaporator fan WR60X10185 (AP3875639 / PS1019114), a low-voltage motor rated about 9.75V / 3.25W that supersedes the WR23X10353 / WR23X10355 / WR23X10364 family. The field tell is a slow or rubbing fan whose blade ticks against frost; GE techs listen for that rubbing note as the sign of a weak motor before pulling the rear cover. We confirm the exact fan by model/serial first, since fitting the wrong-generation motor (WR60X10185 vs WR60X26866) onto the wrong platform is a guaranteed callback.
• A thermistor that lies to the board makes a healthy fridge stop cooling without any obvious dead part. The GE temperature sensor WR55X10025 (AP3185407) feeds cabinet temperature to the main control board, and a drifted (not fully open) fresh-food sensor reads 'cold enough,' so the board stops calling for damper-open / fresh-food-fan cooling and the fridge warms. It's a resistance test, not a guess: a good WR55X10025 reads about 16.3K ohms in 32F/0C ice water and drops toward roughly 6K ohms at room temperature (resistance climbs as it gets colder). An out-of-spec or open reading condemns the sensor rather than the board -- we always check the figures against the spec sheet for the specific board/J1 harness because GE's resistance-vs-temperature tables vary by model.
• On the 2002-2009 GE bottom-freezer and side-by-side era a fresh-food side stuck warm can trace to the main control board WR55X10942 (supersedes to WR55X10942C), which manages compressor, fans and damper timing. The real install gotcha that produces a 'new board but fridge still 60F+' callback on THIS symptom: GE's instruction insert requires eliminating the thermistor wire in J1 pin 2 on ALL bottom-freezer models, plus encoder models with specific serial prefixes (TD2, VD3, ZD2, AF2, DF2, FF2, GF2, HF2, LF2, MF2, RF2, SF2). If the unit's serial matches and a wire is left in J1 pin 2 uncut, the new board mis-reads the sensor and the fresh-food section never pulls down; on an encoder model whose serial does NOT match the list, the wire must be left alone. We match the board's instruction sheet to the model/serial and verify the J1 pin-2 wire before wiring, and condemn the board only after the damper, fan and thermistor all test good.
• A flashing 'FF' on a GE display is a freezer-section temperature alarm (control has seen freezer temperature above normal for roughly two hours), NOT a sealed-system code -- and on a true freezer-cold/fridge-warm call the absence of an FF code is itself diagnostic, because it tells us the freezer is genuinely holding and the fault lives in the fresh-food airflow path (damper WR49X10091, fresh-food fan WR60X26866, thermistor WR55X10025), not in the compressor or evaporator that would warm BOTH compartments. We confirm the freezer is actually near 0F before chasing the fresh-food parts, so we never quote a compressor on a single-compartment warm-up.
• When the fresh-food side is warm AND the back of the freezer is iced edge-to-edge, the root is the defrost circuit, not the damper or fan: a dead GE defrost heater lets frost sheet across the coil and choke airflow, so cold air stops reaching the fridge even though the freezer still holds on conduction. On bottom-mount/French-door units the proper part is the dual-quartz defrost heater kit WR51X10101 (AP4355467, ships with its drain/harness strap, supersedes the single-heater WR51X10032/53/97); a good GE heater reads roughly 10-50 ohms and an open one (often a blackened glass tube) reads infinite. We meter the heater and the defrost bi-metal WR50X10068 (L140-30F high-limit, normally closed at room temp) together at the coil and FIX the defrost circuit before dropping a new damper or fan into a box that still frosts -- otherwise the airflow part just re-ices within days.

GE freezer cold but fridge warm in Toronto — the local specifics

• The recurring GE-in-Toronto pattern on this fault is the air damper first: on GE bottom-mounts and side-by-sides we keep finding the WR49X10091 damper flapper frozen or broken off its motor before the fan or sensor is at fault, exactly the order GE's own diagnostic puts it (damper, then thermistors). The second recurring tell is the 'new board but still warm' return on 2002-2009 bottom-freezers where a previous tech skipped the WR55X10942 J1 pin-2 thermistor-wire cut for the unit's serial prefix.
• We carry to these calls the full GE fresh-food airflow set so we close in one trip: the WR49X10091 damper control assembly, the WR60X26866 fresh-food DC evaporator fan motor (and the legacy WR60X10185), and the WR55X10025 thermistor -- plus a meter to ohm the sensor against spec and, on bottom-mount units showing coil ice, the WR51X10101 defrost heater kit and WR50X10068 bi-metal so a frost-driven warm fridge gets fixed at the source.
