The oscillator appears to be drawn wrong. The feedback capacitor should connect directly from pin 10 to pins 12 and 13, while the 1.2M resistor should connect from pin 11 to pins 12 and 13. In other words, I think you need to omit the 1M resistor which connects to pins 12 and 13.

I have been thinking about the idea too, but mainly for heat output. For airconditioning, one way would be to remove the door and to build it into a wall with the hot side outside. Remember that many refrigerators are not designed to run continuously though. The compressors can tend to overheat.<p>T...

Thanks for getting back on. It must take dedication.
