Causas Comunes
- Sustained throttle-solo riding en max power para 20+ minutes
- Controller heatsink bloqueado por mud o frame bag
- Wiring corto causing controller overload
- Controller MOSFET failure de repeated overheating
- Ambient temperature arriba 40°C compounded por motor heat
Arreglar Steps
Paso 1: 1. Detener immediately — dejar controller cool 30 minutes en shade
Paso 2: 2. Verificar controller housing location (usually debajo battery o en frame downtube)
Paso 3: 3. Retirar any frame bags blocking controller vents
Paso 4: 4. Inspeccionar wiring near controller para melted insulation — corto circuito indicador
Paso 5: 5. Si controller housing es dañado o smells burnt: controller replacement needed (~$80-120)
Paso 6: 6. Preventive: usar pedal assist (PAS 3-5) instead de throttle-solo para extended riding
Paso 7: 7. Engwe controllers son IP65 rated but NO thermally robust — límite continuous max power a 10 minutes
Siempre disconnect el battery antes inspecting wiring.
