Robot mower shows E19 and stops; may be associated with app control or remote commands failing.

Safety first: Ensure the mower is in a safe area before attempting remote control.

Steps:

• 1. Check signal strength: Ensure your phone has a stable internet or Bluetooth connection and is within range of the mower.
• 2. Restart app and mower: Close the Yard Force app, power cycle the mower, then reopen the app and reconnect.
• 3. Re‑pair device: Remove the mower from the app's device list and re‑pair following the Yard Force instructions.
• 4. Firmware update: Check for and install any firmware updates for the mower and app.
• 5. Replace receiver module: If local controls work but remote/app control consistently fails with E19, the remote receiver or connectivity module may need replacement.
