You can pick up a cheap temperature logger: http://www.elitechlog.com/rc-5usb-temperature-data-logger/ http://www.elitechlog.com/rc-5usb-temperature-data-logger/ My apartment has what appears to be the worst refrigerator ever made. It's a cheap GE unit with a single temperature control. You have to choose between freezer burnt steaks or frozen milk. I used that temp logger to confirm what was going on.
