How to Fix / Troubleshooting

Safety first: Immediately turn OFF the mower, remove it from the lawn, and disconnect from the charging station. Do not continue to operate until inspected.

  • Step 1 – Visual inspection: Flip the mower and look for melted plastic, burnt grass, or discoloration near the blade and drive motors.
  • Step 2 – Clear obstructions: Remove any heavy grass buildup or foreign objects around the motors.
  • Step 3 – Check wiring: Open the housing and inspect the Sunseeker wiring harnesses for melted insulation or burnt connectors. Replace any damaged harnesses.
  • Step 4 – Motor test: Rotate motors by hand (via wheels or disc). If stiff or noisy, replace the affected motor assembly.

If the smell persists or visible damage is found, do not use the mower until a full repair is completed.
