How to Set Up an LG Smart Microwave with ThinQ

Before You Start

Set up an LG smart microwave with ThinQ by installing the app, placing the microwave in Wi-Fi pairing mode, and connecting it to your home network. The exact steps vary by model, but the overall sequence is the same. Keep the microwave upright, remove all packaging, and place it in its final position before plugging it in.

Have your phone or tablet ready with the ThinQ app installed. You will need the name and password for your home Wi-Fi network. If you plan to use a voice assistant, have that account available. For help choosing a model before setup, see best LG microwaves and best smart microwaves.

First-Time Power-Up and Placement

Before starting the ThinQ setup, place the microwave on a stable, level surface and leave space around the vents. If the unit has a turntable, make sure the glass plate is seated correctly. Plug the microwave into its own grounded outlet and avoid sharing the circuit with another high-power appliance. For guidance on wiring and outlets, see microwave electrical requirements.

When you first power on the microwave, the display may ask for the time of day or show a welcome screen. Set the clock now or skip it and use the ThinQ app later. If the model has a child lock, turn it off before pairing so the controls respond. You can learn more in microwave child lock.

Download the ThinQ App and Create an Account

The ThinQ app is the hub for compatible LG appliances. Install it from the app store for your phone, open it, and sign in to your LG account or create a new one. The same account can connect other LG appliances later.

After signing in, choose the option to add a device and select microwave as the appliance type. The app may ask for the model number, which usually appears on the rating plate inside the door or on the back of the unit. Entering the model number helps the app prepare the correct setup steps.

Put the Microwave in Pairing Mode

Most smart microwaves do not join a network until you place them in pairing mode. In the ThinQ app, follow the add-device instructions. The app will usually tell you to press and hold a button labeled Wi-Fi or Connect until the display shows a code or the Wi-Fi icon starts flashing.

Keep the phone near the microwave while the app searches. If the display stays blank, confirm that the microwave is plugged in and that the door is closed. Some models require the door to be closed before network pairing will start. For general Wi-Fi connection tips, see how to connect a smart microwave to Wi-Fi.

Connect to Your Home Network

When the microwave is in pairing mode, enter your Wi-Fi password in the ThinQ app. The app sends the network information to the microwave. Wait for the app to confirm the connection, and check the microwave display for a Wi-Fi indicator.

If the app cannot connect, make sure your phone and the microwave are on the same network. Bring the phone closer to the microwave and try again. You can also restart the router and then repeat the pairing steps. For more help, see troubleshoot smart microwave Wi-Fi.

Link a Voice Assistant

Once the microwave is online, open the voice assistant section in the ThinQ app. If you use Alexa or Google Assistant, choose your assistant and sign in when the app asks. The app will link the microwave to that assistant account so you can use voice commands.

Voice command availability depends on the model, the app version, and the assistant. On compatible models, you can start cooking, stop the microwave, or ask for the remaining time. If the assistant cannot find the microwave, close the app, reopen it, and confirm the microwave is still listed as online.

Update Firmware and Set Smart Preferences

After pairing, check for a firmware update. The ThinQ app usually lists the microwave and shows an update prompt when a new version is available. Run the update and do not unplug the microwave until it finishes. Keeping the door closed during the update is a good practice.

Once the update finishes, set preferences such as clock, sound, display brightness, and favorite presets. You can also adjust remote notification settings so the app tells you when cooking ends. For more guidance, see update a smart microwave firmware.

Safety and Food Handling Reminders

After setup, follow standard microwave safety practices. The FDA, which regulates radiation-emitting products, recommends covering food, stirring, and rotating for even cooking, and allowing standing time before checking the internal temperature with a food thermometer.

Only use containers labeled microwave-safe, and avoid using metal in a standard microwave unless the manufacturer says it is allowed. For more on this, see microwave safe containers.

Replacing an Old Microwave

If this setup is part of a kitchen upgrade, do not leave an old microwave in a landfill if it can be reused or recycled. The EPA recommends donating or recycling electronics to conserve resources and to handle materials safely.

Check with local programs for appliance pickup or drop-off options. Before donating, remove personal information and clean the unit. Then set up the new one using the steps above.
