Unplugging a refrigerator

We accidentally kicked out the power cord to our portable refrigerator this week.

I actually had a moisture sensor warning for the rug, but no alarm was connected.
(I have one now that checks the temp AND the moisture from the drain hole.)

I think it defrosted the sides around 4 hours later.

Not a huge deal, we lost one package of hamburger.
We washed the insides down with soap and water and plugged it back in.

It only took about 90 minutes to get to temperature.

The large delta temperature when the compressor runs makes it difficult to determine the actual temperature of our food.

I put the temp sensor in wine glass with a bit of rice to add some mass.

The glass was supported away from the walls of the refrigerator to reduce the influence. I was still unhappy with the delta Temp (Blue line) still confusing the desired temperature reading. I had to add more mass inside the glass OR add insulation to lessen the delta temperature.

Wine Glass full of rice

The next thing I tried was a Yeti mug (Good insulation) with the rice and temp sensor in the bottom with a sock on the top to keep the air from circulating.

The temperature was changing so slowly that I removed the sock. I inserted a spoon into the rice to increase the conductivity into the rice and lowered the set point temperature of the fridge.

Now that the average temperature of the rice is closer to the desired temperature, I need to raise the setpoint to something more reasonable for a refrigerator. (Not a freezer.) Milk freezes at 30-31.5 degrees, so the ideal temperature should be really close to 32 degrees. (Coldest temperature before freezing, down from 38 degrees recommended fridge temp.)

It turns out that the thermostat is 2 degrees higher than actual. (Which is probably why the milk froze.)
