We regret the trouble you have experienced with this refrigerator. The air filter of the machine should not make any restrictions to the cooling performance. It is recommended to check around the vents along the walls of the freezer to make sure there is no blockage. Such interference could restrict air flow in the freezer, including the cooling performance, and will affect the air flow in the refrigerator as well. If this does not resolve the matter, then it may require service. To make service arrangements, you may either contact our Customer Interactive Center at 800-243-0000, or you can check our Repair Provider Lookup on our website, at http://www.lg.com/us/support/repair/support-repair-provider-lookup.jsp.
