Default Help, compressor on freezer gets hot!!

I just picked up a 25ft chest freezer from work. I plugged it in and the inside gets cold but the compressor get pretty hot. What should I look at first to get this to run cooler? I plan on using this as a fermentation box so I will not be pushing it to get down to freezing temps. Should I be concerned or just run a separate fan off of the temp controller as well and have that blow on the compressor as it runs. Thanks

Compressors get hot. Is it reaching temps and shutting off? Are you allowing ventilation space around the unit?

I ran it for about an hour and the inside walls were getting frosty. I did not leave it on long enough to shut its self off. Ventilation is not a problem, I had it sitting in the middle of the garage with nothing around it.

I would try it again (when you are home, just to be safe). Our freezers at work get pretty darned hot when they are first turned on. I think that's normal.

The compressors and skin get hot the inside gets cold that's how they work. The more thermal mass you have inside the less it will run and the lower temp fluctuations you will have.

I was looking for a 25 cu ft and settled for the 19.7 holds 14 five gallon kegs(no collar) and 2 three gallon kegs on the hump. Loaded up mine runs about 2 hours total a day for a bout five minute run time and the compressor only gets warm.

Nice unit enjoy

Damn that's a lot of beer on tap!!! The guys at my work were going to toss this thing away because they said that the compressor was getting hot. I don't believe that they had much in it. I think I will run it again this weekend and see how hot the compressor gets. Would it be better to put buckets of water in it to add some thermal mass? Thanks

Uhm, MOST chest freezer that are not commercial grade, Don't have fans or need them. And the coils are sealed within the walls of the unit. (refrigeration tech)

I'd throw in a few bags of ice, to cool down 25 cu ft even to the warmest setting will take a couple of hours which is a hard thing for these small compressors. On start up I had 6 bags of ice and 6 cold kegs, I removed the ice once the compressor was cycling for about 5 minutes every 1/2 hour or so

Wow tuff room, the guy said he got it from work, AKA commercial grade. I was posting to help the OP, you posted just to mock me.
