Cheap plastic cover produces loud noise
a year ago
It does the job, but the plastic cover that goes around the front of the unit is cheap plastic that tends to vibrate excessively and produces a very distracting noise.

Hi, Jerry. Thanks for sharing your thoughts on the LG Air Conditioner (LW1821ERSM) model. We’re glad to hear that the unit meets your needs. However, excessive vibration and noise from the plastic cover can be quite distracting. We strive to provide top-notch products that exceed our customers' needs and expectations.
To address this, try tightening any loose screws or fittings around the cover. Sometimes, securing the cover more firmly can reduce vibrations and noise.
Please send us a private message on social media @LGUSSupport if you continue to experience issues or need further assistance. We’re here to help and ensure you get the best performance from your LG unit. ^Juvy
