Arthur Martin ADE / ADC Series / Envol Automatique Dryer: Motor drive general malfunction E50; drum drive motor fails to turn or stops unexpectedly during tumble sequence.
On Arthur Martin (Arthur Martin ADE / ADC Series / Envol Automatique Dryer) models: Motor run capacitor degraded (nominal 7–10 μF), defective motor windings (main ~18–25 Ω, aux ~22–30 Ω), open thermal cut-out, or drive triac failure.
Measure motor run capacitor with capacitance meter (must read within ±5% of rating). Check winding resistances with ohmmeter. Hold Départ/Pause and Option buttons firmly for 5 seconds until the red indicator extinguishes and service memory resets.
