What people are saying

Rated 1 out of 5 by from Honestly , it has been the worst service ever - My unit was only a couple hours running , quit , and have still not gotten replacement and we are on week 7

Rated 1 out of 5 by from Not happy! After having my unit for only 5 months, it started making a loud noise while running. I contacted LG for a replacement or to get unit fixed and have not heard anything back. Highly disappointed.

Rated 1 out of 5 by from Essential Parts Missing! It was 90 degrees. We were excited to try two new LG ACs to replace older units. At the last step, we found that the grill assembly was missing a wire/connector (presumably also the pcb) to connect to the unit. I am not sure if there was a product change, but the owners manual tech service used was different from the owners manual included with the product. We finally received the part... wrong again... There is apparently an assembly defect or the team is missing the problem. Still waiting for LG to resolve. Next week will be one month since we purchased! Expensive purchase of something that can't even turn on!

Does anyone know how many fins per inch are on this unit? I got a tool to straighten them & the tool went up to as many as 20 fins per inch but it didn't seem to fit right & none of the lower fins per inch tools worked either. Is it more than 20 per inch?

Asked by: Brandaloo
Regrettably, information with regards to how many fins per inch are on the LG 10,000 BTU Smart wi-fi Enabled Window Air Conditioner, Model # LW1017ERSM is information that would be on the engineering notes or in a service manual which we, unfortunately, do not have access to.
