Got a big chest-type freezer....it's inside my shop, but shop is not climate-controlled....whenever the outside air temp. drops below about 25 degrees, the freezer will shut down....it has a temp. display screen on it, which I keep at the mfg. recommended temp. setting of 10 degrees.
It has an alarm on it, if the temp. rises too much, but I always take a quick glance at the display screen, each time I walk into the shop to make sure it reads 10 degrees....a few days ago, after a night in the 20's, the screen displayed 30 degrees, and a couple of packages of frozen venison on the very top had gotten a bit soft, but still frozen.
At first, I thought the freezer was conking out, even though it's only six years old....I just couldn't see paying several hundred bucks for a repair bill, when I can buy a new one for about $600 bucks.
After several hours of calling around, trying to find a new one, I went back to the shop to find that the freezer was not only running, but the inside temp. had dropped, and was displaying 10 degrees....it was working just fine, and has been ever since.
My question for your science gurus is: "why did the freezer shut down, when the temp. was set on 10 degrees, but the outside temp. is only 25 degrees?"
