Mower shows E19 and stops; message may indicate low internal temperature or battery temperature sensor error.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Operating below minimum temperature, Failed NTC sensor in battery pack, Broken temperature sensor wiring

Safety: Do not charge or operate Li‑ion batteries below the manufacturer’s specified temperature range.

Warm up mower: Move the mower and battery indoors to a dry area (15–25°C) and let it acclimate for several hours.
Attempt restart: After warming, power ON and try to start a cycle. If E19 clears, adjust your mowing schedule to avoid very cold conditions.
Inspect battery pack (advanced): If E19 persists at normal room temperature, the temperature sensor inside the Yarbo battery pack may have failed. Replace the battery pack with an OEM unit.
