No heat

When clothes are not dried, follow this systematic order: (1) Vent properly installed and not blocked? (2) Lint filter clean? (3) Terminal block connections normal (Live 2, Neutral, Live 1)? (4) Touch sensor connected and working? (5) Thermistor normal? (6) Safety/Hi-Limit thermostat normal? (7) Heater resistance approximately 10Ω? If all check out, the PCB is at fault.

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.

The manual lists two sets of motor resistance values: centrifugal switch test (3.05Ω pin 3-4, 3.35Ω pin 4-5) and trouble diagnosis (2.88Ω pin 3-4, 3.5Ω pin 4-5). Both are valid measurements at slightly different points. If readings are significantly outside these ranges or infinite, the motor winding is open.

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.
