OK, someone has their signals crossed......
If you truly do have the residential refer, it DOES have a compressor. It is just like the refer you have at home.
If you have the 4 door, RV style refer, which it sounds like you do, it does not have the compressor, and works just like any other RV refer.
You also stated above that you used a hair dryer and got the compressor to kick on.....so, do you have one or no??
