Won't start

During ignition, a gas dryer draws 6 amps. With the burner ON, it draws 4.5 amps. If the dryer draws amperages above these values, the house wiring, fuse box, or circuit breaker is suspected to be at fault, not the dryer.

Normal sounds include: drum rotation rumble, airflow from blower, motor hum from high-velocity air movement, and gas valve cycling on/off clicks (gas model). Abnormal sounds to investigate: whistling from door seal, thumping from worn drum rollers, ticking from loose wire harness or object in blower, scraping from felt seal or worn bearings, roaring from blower rubbing on housing, and squealing from sticky/frayed belt.

Samsung recommends ring terminals over spade terminals at the terminal block. Spade terminals can work loose causing arcing and overheating. This is highlighted in the 'power does not work' diagnostic flowchart as a first check.

Gas ignition system failures typically manifest as one of three symptoms: (1) Igniter does not glow — check for open flame sensor, open igniter, shorted booster coil, open wiring, bad motor switch, or no power from control. (2) Igniter glows but no ignition — check for open secondary/holding coil, open wire harness, or stuck flame sensor. (3) Flame ignites but goes out — check for radiant sensor contacts opening prematurely, weak gas valve coil, weak Hi-Limit, poor venting, or bad drum seals.
