Topdown, I think I can help you with this issue. I just bought a 27dsrl and had a heck of a time figuring this out. Mine was running all the time while sitting empty in the driveway and I didn't want to pay for that on my electric bill........anyway....hopefully yours is the same as mine......if you reach around the back of it, on the lower right hand side as you're facing it,,,,,,you will feel a dial that adjusts temperature, or if you turn it all the way down it will shut your refer off. Hope this helps you out. It's just in a peculiar spot there where it is hard to see or know about. Take care.
