Refrigerator Repair in Markham — Running constantly / never shuts off

In Markham, runs-constantly calls cluster in the estate stock — Unionville, Angus Glen, Cathedraltown — where panel-ready built-in columns (Sub-Zero- and Miele-class) are cased flush into millwork and the condenser breathes through a top or toe grille instead of open rear clearance. A dust-loaded grille keeps one of those units running long and hot without ever reaching setpoint, so we service it in place: grille off, coil brushed and vacuumed through the opening, the panelled unit never pulled from its casing. Constant running is also the symptom that most often opens the repair-or-replace question, and in Markham replacement carries real friction — a condemned fridge can't go out with ordinary garbage; the City of Markham collects appliances by appointment on a monthly pickup with a per-item fee, and the refrigerant must be recovered by a certified technician before it leaves (markham.ca). That friction, plus the fee, tilts a borderline unit toward the coil clean, gasket or defrost part that keeps the existing fridge alive.
