As I was recently in need of a small refrigerator, I gave $20 for a "Franklin Chef" FCD401BL mini-fridge. It looks to be another no-name Made In China unit, but the compressor was made by Matsushita in Singapore, so I figured it would be OK. The unit itself was in good condition but filthy. I took it to the car wash (!!!) and hosed it off, followed by a lot of hand scrubbing.
Anyway, it does work fine after letting it dry out. However, when I first plugged it in with the thermostat switch set to "0", it started up and ran. Playing with the thermostat a bit to see if it was somehow stuck resulted in what I thought was a little bit of arcing from inside the switch. It's nothing more than the usual (capillary tube?) thermostat setup. I tried to remove the housing to which it is mounted, but there just isn't enough space to do it without risking breakage of the tube leading out of the thermostat.
What's really strange is that although it won't turn off at the 0 position, it does cycle and run normally on any other setting. I'm curious as to why that might be, if anyone has an idea. I would have thought that the thermostat's working contacts would be forced apart or insulated at the "0" setting so the unit would stay off.
It's not a big deal. If I don't want it to run, I will unplug it.
