Won't start

The terminal block must be connected in the specific order: Live 2 (L2), Neutral, Live 1 (L1). Both the 'power does not work' and 'clothes not dried' diagnostic flowcharts check terminal block connections. An improperly connected terminal block can cause the dryer not to power on, not heat, or blow fuses.

This dryer platform has both DUAL and SINGLE heater configurations. DUAL heater: PIN 2-3 = 13Ω, PIN 1-2 = 34Ω. SINGLE heater: PIN 1-3 = 10Ω. When testing, determine which configuration is installed before comparing resistance values. One element of a dual heater can fail while the other works, resulting in reduced heating rather than no heating.

Before touching or replacing any PCB (Main or Sub), you must discharge static electricity from your body by contacting the power plug first. Static electricity from the resin parts of the dryer or the human body can damage electronic components. This is explicitly required before any PCB work.

All moisture and temperature sensors route through the single CN7 7-pin connector. Pin assignments: Pin 2 (Yellow) + Pin 7 (White) = Cycling Thermistor2 (238.231KΩ), Pin 3 (Blue) + Pin 6 (Red) = Cycling Thermistor1 (10KΩ), Pin 4 (Pink) + Pin 5 (Orange) = Sensor Bars (∞Ω dry, 190Ω wet). Disconnect CN7 to test all sensors in one procedure.
