I'm glad that you found a solution. I don't have AC and I noticed that especially on hotter days that my refrigerator doesn't cool well and it's only about 6 years old. It also has many new parts because it always had a problem keeping things cool so the repairman ended up having to add more freon to it. I ended up rolling it out and there was a lot of cat hair under it so I cleaned all of that up. Later in the week I tried to buy a condensor brush but OSH didn't have any so I ended up buying a dryer brush instead. I used it and I couldn't believe all of the cat hair that I got from brushing the condensor. I still have the setting on 7 and 9 is the coolest setting. This setting used to freeze some things in the refrigerator but so far it hasn't this time. I sure hope that I won't have to end up getting another new refrigerator any time soon. My last one lasted for a little over 17 years. They sure don't make things like they used to.
