Samsung Dryer Repair in Toronto — Not drying (clothes still damp)

• A film-blinded moisture sensor is the signature Samsung "runs a full cycle but clothes come out damp" call -- the part is the DC61-02627A stainless moisture-sensor bar (genuine Samsung OEM; PartSelect PS4206812, also crosses to AP4578789, fitted across the DV42/DV45 line). The two metal strips sit at the front of the drum by the lint-filter opening and the control ends Sensor Dry when tumbling clothes bridge them as 'dry.' Fabric-softener and dryer-sheet film coats the bars and fakes a 'dry' reading, so the machine shuts off early with wet laundry -- the documented symptom set is 'won't stop / advances early / takes too long when clothes are already dry.' We scrub the bars clean (alcohol or fine steel wool) and run a Sensor-Dry test load FIRST; only if readings stay erratic do we quote the DC61-02627A, because a sub-$25 sensor mimics a far pricier heat fault on this platform.
• Restricted exhaust is the #1 real not-drying cause on Samsung and the machine self-reports it through the on-board Vent Blockage Test. Samsung's official codes are Cg / Clg (vent clogged), C80 / C8 (~80% blocked) and C90 / C9 (over ~90% blocked) -- run from the panel, these tell you the duct between the dryer and the outside hood can't exhaust. A near-blocked run traps heat so the load tumbles warm but never dries, and a chronic restriction is exactly what then overheats the box and trips the HE flag below. We treat a Cg/C90 result as a VENT diagnosis first (lint packed below the screen, crushed foil transition hose, blocked exterior hood), because clearing the duct is cheaper than any part owners brace for.
• HE / HE on the display during a not-drying call is a heating ERROR (overheat/heat-fault flag), not automatically a dead element: on DV42/DV45 platforms the most common trigger is a restricted exhaust that lets exhaust temperature spike, so the control cuts heat early and the load finishes damp. The thermistor (DC32-00007A, on the blower housing, spec ~10K ohms at 77F) feeds that decision -- a drifted sensor reading falsely high tells the board it's hotter than it is, so it cuts heat and clothes stay wet. We bench-check the DC32-00007A against the 10K-at-77F spec and vacuum the lint chamber before quoting, since an HE on Samsung is far more often a clogged vent than a dead sensor.
• A weak or partially-grounded heating element shows up as not-drying-but-warm rather than dead-cold no-heat: the DC47-00019A element (5300W/240V; OEM supersession AP4201899 / 2068550 / PS4205218) can sag and short to its own housing and make low, lukewarm heat that passes a casual touch test but won't carry moisture out. We ring the element terminal-to-terminal AND to its metal housing on every slow-dry call, because a short-to-case heats any time the drum runs and gives that warm-but-won't-dry pattern -- a truly open coil reads infinity and gives no heat at all, so the warm-but-damp signature is the one that points at a weak/grounded element versus an upstream open safety.
• A clogged or softener-blinded lint screen is the cheapest real not-drying cause and needs no parts: a screen caked with invisible fabric-softener film (or packed with lint each load) chokes airflow so the heated air can't carry moisture out, clothes finish warm-but-damp, and the dryer can even start derating toward a Cg/C80 vent code. Samsung's own 'clothes are not dry' guidance has owners wash a film-coated screen in warm soapy water and dry it fully. We check the screen and the lint chute below it before opening any panel, because restored airflow alone fixes a large share of 'won't dry' calls on this brand.
• Lint bypassing a worn front drum felt seal is the not-drying call that's really an airflow-leak job: when the DC97-07618A front felt seal (replaces AP4453798 / PS4218879 / 3998155) wears through, the drum drops out of true and heated air leaks around the front bulkhead instead of pulling through the load and out the exhaust -- the brand profile already flags lint streaks on clothes tracing to this seal. The result is long, damp cycles plus lint on the laundry. On a slow-dry call with lint streaks we renew the DC97-07618A while the front is open so the seal isn't quietly bleeding off the airflow the heater needs.
• An overheat that already tripped the safeties presents as warm-then-cold, never-finishes drying: a blown one-time thermal fuse on the blower housing (DC47-00016A; crosses to AP4201894 / PS4205213) or a tripped high-limit thermostat (DC47-00018A) plus heater-circuit thermal cut-off (DC96-00887A / DC96-00887C, with bracket) means a restricted vent cooked the heat box, so the drum tumbles but heat dies and the load stays wet. The honest fix is never just the fuse -- a blown DC47-00016A means airflow restriction opened it first, so we meter the heat chain cold, replace only what's open, AND clear the full vent/lint path, or the new fuse re-blows within a load or two.

Samsung not drying (clothes still damp) in Toronto — the local specifics

• The recurring Toronto pattern on Samsung not-drying is the softener-film moisture sensor paired with a restricted house vent: heavy fabric-softener and dryer-sheet users coat the DC61-02627A bars so the dryer ends Sensor Dry early, while a lint-packed basement duct run quietly steals the airflow -- the two stack so often that we always clean-and-test the sensor AND run the Vent Blockage Test on the same call before quoting any part.
• We roll to these calls carrying the DC61-02627A moisture-sensor bar, the DC32-00007A thermistor, a DC47-00019A heating element and the DC47-00016A / DC96-00887A thermal-fuse pieces, plus a DC97-07618A front felt seal and vent-cleaning gear -- so a film-blinded sensor, a drifted thermistor, a weak element or a simple airflow restriction can all be diagnosed and finished in one visit.
