To connect the LREL6325 to the LG ThinQ app, scan the QR code on the product or install ThinQ from the app store, sign in, tap the add button and follow the prompts; the Wi-Fi icon on the control panel lights when connected. LG says only 2.4 GHz networks are supported, the network name should use letters and numbers only, WEP security can make setup fail (use WPA2), mobile data on the phone should be off, and a range extender may be needed if the range is far from the router. To reconnect or add a user hold the Wi-Fi button for three seconds.
Differential
Likely causes of “LG range or oven will not connect to Wi-Fi or the manufacturer's app”, and how to tell them apart
- 1
The router is on 5 GHz only
What separates it Setup never finds your home network in the list the app offers
How to confirm Set the router to 2.4 GHz and reconnect
- 2
A network name with special characters
What separates it Connection fails at the password step even though the password is correct
How to confirm Use a network name of letters and numbers only
- 3
Mobile data on the phone
What separates it The app cannot reach the range's own setup network during pairing
How to confirm Turn the phone's mobile data off during setup, then try to pair again
- 4
A weak signal at the range
What separates it Setup takes a very long time or fails partway through the pairing steps
How to confirm Move the router closer or add a range extender

Try in this order
0 of 5 completedPrepare the network
ReversibleConfirm the router has a 2.4 GHz band and the network name uses letters and numbers, with WPA2 security rather than WEP.
Connect
ReversibleScan the range's QR code or search ThinQ in the app store, sign in, tap add and follow the instructions.
Check the icon
ReversibleWhen the Wi-Fi icon on the control panel is lit, the range is connected to the network.
Fix a password prompt
ReversibleOn certain phones look for a network beginning LG under Settings then Networks; if it is LGE_Appliance_XXXX, enter XXXX twice as the password.
Retry or reconnect
ReversibleUnplug the range for about a minute and retry; hold the Wi-Fi button three seconds to reconnect or add another user.
Model-specific
What is true of this model and not of its siblings
- LG ThinQ requirements
- 2.4 GHz Wi-Fi only, a network name of letters and numbers with no special characters, WPA2 security (WEP can fail setup), and the Wi-Fi icon lit on the control panel when connected. Hold the Wi-Fi button three seconds to disconnect or re-pair.
- Smart Diagnosis
- In the ThinQ app choose Smart Diagnosis, press START for three seconds, and hold the phone's mouthpiece within 3/8 inch of the Smart Diagnosis logo on the control panel until the tones stop and a countdown ends.
- LREL6325 controls
- This model takes temperatures and times from a number keypad, has a Settings button for the oven options, and adjusts the cooktop Warm Zone with a Level button. LG's LREL6323 uses +/- keys and a Clock hold instead, so button steps for that range do not match.
- Electrical and size
- 6.3 cu. ft. oven, 30 by 46 1/2 by 26 1/2 inches, 36 inches to the cooking surface. 120/240 V at 12.9 kW or 120/208 V at 9.7 kW, on a 40 or 50 amp range cord with a 1 3/8 inch connection opening.
- Rack care
- Racks that stick can be wiped on their edges with a little olive or vegetable oil. Self Clean discolors silver racks and makes them hard to slide, so take them out first. Never cover whole racks with foil, because it restricts air flow, and use a foil-lined sheet pan under acidic or sugary pies instead.
- Cooktop care
- Clean the glass-ceramic top after every use. Scrape sugary spills with a blade scraper while still warm, wearing an oven mitt, remove metal marks and mineral deposits with a glass-ceramic cleaning creme, and avoid sliding metal utensils, coarse salt or sand under pans, which scratch the glass.
- Cookware advice
- LG recommends flat-bottomed, straight-sided, heavy-gauge pans that match the element, with tight lids, and flat-bottomed woks only. A pan should not extend more than half an inch to an inch past the ring, and using a big element for a small pan wastes energy and leaves hot element exposed.

Where the manufacturer's article stops. Button sequences on this page are the manual's LREL6325* ones (number keypad, Settings button and Level button), which differ from the +/- and Clock-hold steps LG gives for the LREL6323*. Trim levels and other LG ranges differ, so confirm the model on the rating-plate label before relying on a specific sequence.
