Did 1st defrost today. We had a picnic here last Saturday (32nd annual) and everyone just HAD to check it out so the evaporator iced up quite a bit. Shut it down by pulling the plug and put a pan (old aluminum ice cube tray) full of hot tap water in the lower compartment, refilled it once, and 20 min later dumped the chiller tray and ice cube tray. Never even lost the chill from all the drinks in there. Nice...

LOL it is always interesting how people are fascinated with these old fridges!

Yes it is interesting how much attention they can attract. I always get the question how much did my electric bill go up .

People have been brainwashed to think like that. I always remind them that electricity cost was almost 7 times higher in the 30's than now; so efficiency was an even more important selling point back then than it is now.

The rates show 2.2 and 4 amps. I am making the assumption that it's 4 amp starting (rather than locked rotor) so even that is far below the latest "high efficiency" unit.

I'm not sure exactly how the rating was calculated on these; but it may have been a min / max running current. In other words, the 2.2A demand would be with the evaporator fully frosted towards the end of a cycle (minimum load on motor) and the 4 amps was the max, during initial pull-down in a hot room.
The best way to know the energy cost is the actual power (watts) draw. With an AC motor, the amps necessary to run the motor and the actual billable power use may differ greatly.
