LG Refrigerator – Smart Diagnosis Procedure. Step By Step Guide

LG Refrigerators are equipped with an excellent feature called Smart Diagnosis. The feature involves the appliance diagnosing itself for problems and transmitting information through sound tones. Those tones can be interpreted to quickly understand and resolve fridge problems.

You can perform a Smart Diagnosis for your LG refrigerator in two ways. The first is calling LG’s Customer Service hotline and playing your fridge tones to them through the phone’s mouthpiece. You can also do so through the LG ThinQ app, which will interpret the tones and tell you what’s wrong with your fridge.

This guide will help you understand what LG’s Smart Diagnosis feature is all about and guide you through each step of the process.

What Is The Use Of LG’s Smart Diagnosis?

Smart Diagnosis enables your fridge to play a series of tones from a speaker. Those tones carry data that can be interpreted to diagnose the fridge’s performance and quickly identify active errors.

Thanks to those tones, you can quickly transmit fridge data to LG for them to troubleshoot further. They can then advise you on the next steps, whether it’s instructions on fixing the problem yourself or scheduling a technician to fix it for you.

The Smart Diagnosis tones are played by a tiny speaker built into the refrigerator’s body. As that happens, you can transmit those tones to LG in two ways:

  • Customer Service: When speaking to an LG customer service agent, they’ll tell you when to put your phone to the Smart Diagnosis speaker. Then, they’ll use their system to analyze the sounds and tell you what to do next.
  • LG ThinQ App: The ThinQ mobile app can also interpret the same tones and present the information on-screen. The app will then tell you if your fridge has a problem and provide tips on fixing it.

How Do You Use Smart Diagnosis On An LG Refrigerator?

As you read above, there are 2 ways you can perform Smart Diagnosis on your LG refrigerator. The first is with the help of LG Customer Service, and the second is through the LG ThinQ app.

Here’s a step-by-step guide on how to use both approaches:

Smart Diagnosis Through Customer Service

Here’s how you can perform Smart Diagnosis on your fridge with the help of LG Customer Service:

Step 1: Contact The LG Customer Service Center

The first step in this process is to contact the LG Customer Service Center by phone.

No in-home service calls. No appointments.

Be sure to use a mobile phone or one close to your refrigerator. That’s because you’ll need to lift the mouthpiece to the Smart Diagnosis speaker in the fridge when prompted by the Customer Service Agent (later in Step 3).

Step 2: Follow Customer Service Agent’s Instructions

Once you get an LG Customer Service Agent on the line, explain your fridge problems to them. They will likely ask follow-up questions to understand your situation a little better.

The agent will prompt you to begin the Smart Diagnosis process when necessary.

They’ll give you instructions on which buttons to press based on your particular LG fridge model.

Follow their instructions exactly as described.

Step 3: Hold Phone Mouthpiece Near Speaker

Once you follow the agent’s instructions to begin the Smart Diagnosis process, they’ll tell you to hold the phone’s mouthpiece near the speaker in your fridge.

The goal is for the fridge to transmit those tones through your phone call to the customer service agent. Then, the computer on their end will interpret the tones and provide the agent with more data to help you.

Typically, you’ll have to open the fridge door and find the speaker at the top of the appliance’s frame. You’ll see a Smart Diagnosis label next to the speaker.

Hold your phone’s mouthpiece at the speaker until the tones stop and you hear a second chime. That chime marks the end of the process.

Then, you can get back on the phone with the Customer Service agent.

Step 4: Customer Service Will Interpret Data

The Customer Service agent will need a few moments to interpret the data transmitted by your LG fridge. During that time, they’ll understand your fridge’s problems, including any error codes that require attention.

Step 5: Discuss Next Steps With Customer Service

Lastly, the Customer Service agent will provide instructions on how to fix your fridge’s issues. Then, if necessary, they’ll help you schedule a technician to visit your location and fix the refrigerator for you.

Smart Diagnosis Through the LG ThinQ App

You can also perform a Smart Diagnosis on your LG refrigerator using the ThinQ app. Here’s a step-by-step guide for how to do that:

Step 1: Open The ThinQ App

Firstly, open the LG ThinQ app on your smartphone. Then, if you haven’t done it already, you should set up the ThinQ app and connect your fridge to it. That will allow the refrigerator to communicate wirelessly with the app via WiFi.

Step 2: Select Smart Diagnosis Option

Once in the ThinQ app, open the menu in the top right corner and select the Smart Diagnosis option.

Doing so will present you with a list of your connected LG appliances with Smart Diagnosis capabilities, including your refrigerator.

Step 3: Select Your LG Refrigerator

Look for the refrigerator that you want to diagnose on that list. Select it and press on ‘Get Started’.

This process will take a few moments. However, unlike the earlier approach, performing a Smart Diagnosis does not require you to bring the phone up to the fridge’s speaker.

Instead, the fridge transmits the Smart Diagnosis data directly to your phone over WiFi.

Step 4: Read Analysis Details

When the analysis is complete, the ThinQ app will display its findings. It’ll show you a detailed report on your fridge’s performance, including what’s working and isn’t.

Besides that, it’ll also display any active error codes that require your attention.

Step 5: Decide On Next Steps

The Smart Diagnosis analysis will also provide tips on fixing any issues your fridge is experiencing. You can try to fix any problems yourself, or you can use the app to contact LG Customer Service for additional help.

You can also schedule a technician visit through Customer Service when you discuss the matter with them.
