LG ThinQ Wi-Fi Password Case Sensitivity and Special... | appliancefaults.com

Technical Background:

The refrigerator's MCU (Microcontroller Unit) handles the Wi-Fi connectivity. It interprets the password entered through the ThinQ app and attempts to authenticate with the Wi-Fi router. Incorrect or unsupported characters in the password can cause authentication failure. The MCU requires a stable 3.3V DC supply for proper Wi-Fi function.

Symptoms:

The LG ThinQ refrigerator is unable to connect to the home Wi-Fi network. The ThinQ app displays an error message related to incorrect password or connection failure. The Wi-Fi icon on the refrigerator's display may show a weak signal or indicate that it is not connected.

Possible Causes:

Incorrect Wi-Fi password entered.
Special characters in the Wi-Fi password not supported by the refrigerator's firmware.
Wi-Fi router incompatible with the refrigerator's wireless protocol (e.g., 802.11 b/g/n).
Weak Wi-Fi signal strength at the refrigerator's location.
Refrigerator's Wi-Fi module malfunction.

Solution:

1

Verify the Wi-Fi password and ensure correct capitalization. Double-check each character.
2

Change the Wi-Fi password on your router to a simpler one using only alphanumeric characters (A-Z, a-z, 0-9). Avoid special characters like !, @, #, $, %, ^, &, *.
3

Check the Wi-Fi signal strength at the refrigerator's location using a smartphone or Wi-Fi analyzer app. If weak, consider moving the router closer or using a Wi-Fi extender.
4

Power cycle the refrigerator by unplugging it from the 120V AC outlet for 5 minutes. This will reset the Wi-Fi module.
5

Update the refrigerator's firmware to the latest version through the LG ThinQ app. This may include fixes for Wi-Fi compatibility issues.
6

If the problem persists, try connecting the refrigerator to a different Wi-Fi network (e.g., a mobile hotspot) to isolate the issue.
7

As a last resort, perform a factory reset on the refrigerator's Wi-Fi module, if available in the settings. Refer to the user manual for instructions.

Safety Warning:

Always unplug the refrigerator from the 120V AC outlet before performing any troubleshooting or repairs. Lockout/Tagout (LOTO) procedures should be followed to prevent accidental re-energizing of the appliance.

Prevention:

Use a simple alphanumeric Wi-Fi password for optimal compatibility. Regularly check for and install firmware updates for the refrigerator to ensure compatibility with the latest Wi-Fi standards and security protocols.

Expert Tip:

If you continue to have problems, try temporarily disabling the 5 GHz Wi-Fi band on your router and only using the 2.4 GHz band. Some older appliances have compatibility issues with the 5 GHz band. Also, try enabling guest network with only 2.4 GHz.
