The moisture sensor bars have specific measurable resistance values: ∞Ω without laundry (open circuit) and approximately 190Ω ± 10% with wet clothes placed on them. These values are measured between Pink wire Pin 4 and Orange wire Pin 5 after disconnecting the harness. If values are outside this range, the sensor bars may be dirty or faulty. The cycling thermistor connects on Blue (Pin 3) to Red (Pin 6) and should read 10KΩ at 25°C.

Gas model dryers have specific amp draw values that can help diagnose problems: 6 amps during ignition, 4.5 amps with the burner on. If the dryer is drawing amperages above these levels, the house wiring, fuse box, or circuit breaker is suspected to be at fault — not the dryer itself. This is a useful field test before tearing into the dryer.

Samsung explicitly recommends ring terminals over spade terminals for power cord connections to the terminal block. Spade terminals can work loose over time, causing arcing, overheating, and power delivery problems. This is highlighted in the 'power does not work' diagnostic flowchart with the note: 'Encourage ring terminals use, but when use spade terminals, confirm whether confirmed finish.' Always check terminal tightness as the first step in power-related troubleshooting.

The terminal block must be connected in the specific order: Live 2, Neutral, Live 1. Incorrect connection order can cause the dryer to not work at all or produce incorrect voltage to components. This is checked in both the 'power does not work' and 'clothes not dried' diagnostic flowcharts.
