LG ThinQ Wi-Fi Indicator Light Not Blinking:... | appliancefaults.com

Technical Background:

The Wi-Fi module on LG ThinQ appliances relies on a dedicated microcontroller (MCU) to manage the wireless connection. The MCU receives commands from the main control board. If the voltage path to the Wi-Fi module is disrupted, or the MCU itself is faulty, the indicator light won't activate and the appliance won't connect.

Symptoms:

The homeowner reports that the Wi-Fi indicator light on their LG ThinQ appliance is not blinking, even after holding the Wi-Fi connect button for the prescribed duration. The appliance is unable to connect to the home's Wi-Fi network.

Possible Causes:

Defective Wi-Fi module
Main control board failure
Loose wire harness connection to the Wi-Fi module
Power supply issue to the Wi-Fi module
Software glitch requiring a reset
Interference from other wireless devices

Solution:

1

Disconnect power to the appliance by unplugging it from the outlet or switching off the breaker in the breaker panel. Wait 5 minutes.
2

Reconnect power and attempt the Wi-Fi connection procedure again, holding the button for the specified time (usually 3-5 seconds).
3

If the light still doesn't blink, locate the Wi-Fi module. It's often near the main control board.
4

Using a multimeter, check for the correct voltage at the Wi-Fi module's power connector. Refer to the service manual for specific voltage requirements (typically 3.3V DC or 5V DC).
5

Inspect the wire harness connecting the Wi-Fi module to the main control board for any loose connections or damaged wires. Reseat the connectors.
6

If voltage is present and connections are good, the Wi-Fi module is likely defective and needs replacement. Order the correct replacement part number.
7

If voltage is absent, the main control board may be faulty and preventing power from reaching the Wi-Fi module.

Safety Warning:

Always disconnect power to the appliance before performing any diagnostic or repair procedures. High voltage components are present. Follow Lock Out/Tag Out (LOTO) procedures to prevent accidental power-up during repairs.

Prevention:

Periodically check for firmware updates for your LG ThinQ appliance through the LG ThinQ app. Ensure your home Wi-Fi router is functioning correctly and not experiencing excessive interference.

Expert Tip:

On some LG models, repeatedly pressing and holding the Wi-Fi button may trigger a factory reset, potentially resolving software glitches affecting the module.

Frequently Asked Questions

•Where can I find the service manual for my specific LG ThinQ model?

You can usually find the service manual on the LG website under the 'Support' section for your specific appliance model, or through a paid service manual provider like ApplianceJunction.

•What is the typical lifespan of an LG ThinQ Wi-Fi module?

The lifespan of a Wi-Fi module can vary, but generally, they should last for at least 5-7 years under normal operating conditions. Factors like power surges or extreme temperatures can reduce their lifespan.

•Can I replace the Wi-Fi module myself, or should I hire a professional?

If you are comfortable working with electronics and have experience using a multimeter, you may be able to replace the Wi-Fi module yourself. However, if you are not comfortable or familiar with appliance repair, it is recommended to hire a qualified appliance technician.
