What people are saying

Rated 2 out of 5 by from Issue not resolved Made contact with LG. Got & email that someone will contact me, then a few days later I got a text from LG saying we went through trouble shooting & that we didn’t contact them. Sorry we never got any information about troubleshooting anything & was never contacted by anyone to resolve the issue.

Rated 1 out of 5 by from Terrible quality Bought it in April 2022 did not work for 6 month have not been able to schedule a repair.

Rated 5 out of 5 by from Quiet and Effective I like that it has an energy-saving setting, and it is a very quiet air conditioner. The filter is easy to remove, and a light will let us know when that needs to be cleaned. The 10,000 btu's cools our 480 sq. ft.

This unit came with the condo, when I plug it in it just off on beep never comes on after pushing re-set just a small single beep. Suggestion

Asked by: Robert194675
Regrettably, the LG10,000 BTU Smart Wi-Fi Enabled Window Air Conditioner, Model # LW1017ERSM may require repair service. The appliance is equipped with an automatic error-monitoring system to detect and diagnose problems at an early stage. If the appliance does not function properly or does not function at all, check your condo's fuse/circuit breaker box and replace the fuse or reset the breaker. If a power failure has occurred, turn the mode control to off. When power is restored, wait 3 minutes to restart the air conditioner to prevent tripping of the compressor overload. If the current interrupter device on the plug for the air conditioner is tripped, and you have pressed the RESET button located on the power cord plug and the RESET button will not stay engaged, you will need to discontinue use of the air conditioner and contact a qualified service technician. You can contact our Customer Support Center at (800) 243-0000 or visit us at https://www.lg.com/us/support/find-service-center to use the locator to find an LG Authorized Service Center in or near your area that you can contact to make arrangements with for repair service...^Ivan
