1972 Duster Build with my Daughter
The one is on the out side of the box.
According the the DMT instructions only '73 had the freeze up switch, not sure why, seems like a great idea...
To test mine it was in the freezer since we started. If it senses freeze up it opens and shuts off the compressor.
Yup, open circuit when we took it out of the freezer. Held the probes one to see what happens as it warmed up..
There was an audible click after a minute or two and yup short circuit, compressor would have come back on.
Here is the alien probing into the core. There is a hole down the fins between the tubes where this probe is inserted.
DMT gives you the necessary gasket for the one year only switch
New foam on the fresh air damper, make sure the probe is out of the way so it will open all the way.
Make sure you use the short bolt in this corner. The shape of the box requires this to be a short bolt.
Resistor installed.
