Awhile back, I converted my chest freezer to a refrigerator by using an external temperature control. The external thermometer unit turns the freezer on and off to keep temperatures at a refrigerator's temperature.
I am looking at my chest freezer's usage yesterday using the Kill A Watt meter and noticed that normally it says .4 watts, but 100 volt-amps. This is when the unit is not powered on.
If there is a low voltage system inside the unit, there will be a transformer inside changing voltage at all times. This is always going to be an inductive load.
100VA seems a little high for that, but I don't know much about your fridge or the Kill-a-Watt device. It's possible the resolution on the KAW isn't small enough to see a 20VA load; it could just report as 100VA. It's also possible there's enough stuff going on that it's actually drawing 100VA. 100VA isn't THAT much power when compared to most refrigeration circuits, so it's difficult to know.
Well, that makes sense. And I was thinking of hooking the refrigerator up to a timer so that it would only turn on every three hours, just in case it was drawing some massively wasteful phantom load despite the external thermostat.
To do this, I had to unplug stuff. I unplugged the kil-a-watt meter, which reset it. I plugged it back in and now it doesn't show that reading. Now, it shows what makes sense: when the fridge is off, it consumes zero watts and zero VA.
Let's hope it was just a weird error in the meter.
