Black oil like substance leaking from bottom left side
 

Woke up with oil leak on floor. Motor?

Your Model Number is incorrect, please check it.

The only thing with oil in it, in a fridge is the motor.
So if it came from the fridge you have a major problem.
I would shut off the unit till you can determine the source.

Model # from Sears Manual 253 or 970
 

Label inside door is Model 253-73754302.

Thanks. I am sure it's MAJOR!

Motor?
 

Model Sears Kenmore 253-73754302. No motor shown in the schematic. I suspect going to get a new refrig shortly.

Thanks!

You had said motor so I used the same terminology actually it is an oil filled compressor.

Black stuff is likely
 

It is possible your compressor is overheating and the shell is oozing its bonding/sealing gasket material becaue of the heat. The lubricating oil could also be leaking out a bad gasket. It is either failing on its own, or a continuous call for cooling (stuck thermostat or dirty coils) is making it run too much. There is usually a thermal limit switch built in to the compressor which is likely bad in addition to the other things. (This would allow it overheat).
