Additional Tips and Troubleshooting

  • Ensure Proper Power Supply: Make sure that your MRCOOL indoor unit is properly powered on and receiving electricity before attempting to connect it to WiFi.

  • Check for Firmware Updates: The MRCOOL app may prompt you to update the firmware on your AC unit. Follow the instructions provided to ensure your unit is running the latest software version.

  • Restart the WiFi Connection: If you’re having trouble connecting your MRCOOL AC to your WiFi network, try restarting the process by powering the unit off and on again, then re-entering the WiFi setting mode.

  • Verify Router Settings: Ensure that your home router is configured to broadcast a 2.4GHz WiFi network, as the MRCOOL Smart Kit is not compatible with 5GHz networks.

  • Check for Interference: Nearby electronic devices, thick walls, or other obstacles can interfere with the WiFi connection. Try moving your MRCOOL unit or router to a different location to improve the signal strength.
