refrigerator won't stay on. Is there a diagnostic manual? It looks like an electronic model with just a slide control, no display.

Compressor vibrating, but cold to the touch. Fan inside blowing cool air, but not freezing cold.

I ran it overnight. I was running but not cold this morning, but a few hours later it's cold like it should be. I also notice the start up sequence in the tech notes, where it runs for 115 seconds, then turn off for 5 to 10 minutes...

Further update, few hours later: The evaporator fan is now running but the compressor and condenser fan are not running. The inside is not cold.

Ok, then we have to determine when the compressor is running what is the frost pattern of the evaporator coil in the freezer?

Normal would be a thin layer of frost on all the coils from top to bottom.

If the frost pattern is good, then it seems like a problem in the thermistor or control board causing it to keep cutting off.

Here's the thermistor for your model:

Here's the control board for your model:

I put it in service mode. In step 1, the compressor and condenser fan did not come on. In step 2, the heater came on. In step 3, the light came on, and step 4, the evap fan came on. After I ended the test, the compressor and condenser did come on for a couple of minutes.

That seems to indicate the control board is malfunctioning, doesn't it to you?

I "touched up" the control board with a soldering iron a few hours ago. So far it's still running.

Yes, hopefully that's all it needed.:)
