Possible Causes

Internal temperature above safe limit, Faulty temperature sensor on PCB or battery, Blocked ventilation, Mower stored in direct sun while charging

How to Fix / Troubleshooting

Safety first: Do not operate or charge the mower if it feels excessively hot.

Steps:

  • 1. Move to shade: Relocate the charging station to a shaded area. Allow the mower to cool to room temperature.
  • 2. Check ventilation: Ensure vents on the mower housing are not blocked by dirt or grass.
  • 3. Inspect sensor: Open the mower and locate the temperature sensor (often on the PCB or attached to the battery). Check for dislodged or damaged sensors.
  • 4. Environmental limits: Confirm you are operating within the temperature range specified by Yard Force (typically 0–40°C).
  • 5. Replace sensor: If E17 appears even at normal temperatures, replace the temperature sensor or the PCB section that includes it.
