My Haier Mini Fridge Is Not Cooling Properly

Last year, I purchased a Haier mini fridge and it's not doing a great job at keeping things cool. The cooling power has taken a major hit in just one year. I really dig this mini fridge because it doesn't take up much room, yet it can hold a ton of stuff. During the summer, it's a breeze to fit my water bottles in it. The only issue I had with it initially was the noise level, but I eventually adjusted to it. Man, this cooling problem is seriously getting on my nerves. I was able to schedule a technician appointment with customer service, and it's set for three days from now. I really hope they can get this issue resolved quickly. Otherwise, I'll ask for a replacement since it's still covered by the warranty.
