Whirlpool Refrigerator Repair in Toronto — Not cooling

• The #1 not-cooling root on Whirlpool-built fridges (Maytag, Amana, Inglis, KitchenAid badges) is the rear-evaporator defrost circuit — the bimetal defrost thermostat (WPW10225581), the defrost heater (WP12729128), or the adaptive-defrost control board — which ices the evaporator until the freezer holds but the fridge warms.
• On adaptive-defrost-control (ADC) models, test the board's defrost TRIGGER, not just continuity — a board that powers but never initiates a defrost cycle mimics a dead heater and gets misdiagnosed.
• A "PO" display after a power event is an informational power-outage flag, not a fault code — confirm cabinet temperatures and clear it before condemning any defrost part.
• Crisper-drawer water pooling on bottom-mount and French-door models is the classic clogged defrost drain (a frozen drain tube), not a sensor fault — clearing the drain restores the cooling balance.
• French-door WRF/WRX units route the fault to the main control board (W10312695) about as often as to the bimetal, so we meter the heater circuit and the ADC trigger before choosing between a $20 thermostat and a $200 board.

Whirlpool not cooling in Toronto — the local specifics

• A recurring Toronto pattern on Whirlpool French-doors in condo kitchens: the defrost drain freezes behind the rear panel, so the fridge warms while the freezer stays cold — we clear the drain and verify the heater and the ADC trigger before quoting the control board.
• We carry the WPW10225581 bimetal and the W10312695 board to most Toronto not-cooling calls, so the common Whirlpool defrost fixes close on the first visit.
