The last few weeks our ice cream sandwiches have been awful. I\u2019m throwing away ice cream sandwiches, and I\u2019m only marginally pickier than my dog. They\u2019ve been gummy, almost squishy.<\/p>\n

We have been suspicious of the refrigerator since we smelled a hot electric odor\u2014like burning dust. I monitored the fridge with the RIMU<\/a>, and it looked more or less reasonable. I monitored the freezer too, for one night. It is looking less good.<\/p>\n

In addition to the short-lived odor, there is another reasons to be suspicious. The fridge gets warm on the outside, notably warmer than it used to.<\/p>\n

Normal fluctuation in freezer temperature should be about 5 degrees<\/a>, measured with a mass-damping technique\u2026that I did not employ. I estimated the air temperature variation, not the food temperature variation. The air temperature variation is larger. The air temperature swings through a larger range than I would expect.<\/p>\n

The average temperature, though, looks altogether too high: 16\u00b0F. The normal target temperature is 0\u00b0F. I\u2019m assuming some of the spikes are because we were accessing the freezer, but they may all be defrost cycles.<\/p>\n

We\u2019ll continue fiddling with the temperature control, but likely the freezer is singing its swan song. That\u2019s one note, about 0.25 millihertz.<\/p>\n","protected":false},"excerpt":{"rendered":"
