The Door (lid) seal is "ok" - slightly warped on one side, but a bit of weight makes it seal tight. For testing, I put enough weight on it to keep it sealed.
Not full of product, just the empty unit. I know that helps with efficiency, but I would have thought the bottom of the cooler would get below 50* regardless. I measured this with my laser thermometer.
The fan that sits down in the cooler itself is running fine.
I'll call a couple of the local places and ask around a bit. I also know a couple of local HVAC guys that I can ask, although I would think that home AC units are a bit different.
