I have an old Westinghouse freezer (left behind by PO) that when plugged
in runs for half a second, stops, sits for about ten second, then kicks
on for another half second, stops, and so on. Any thoughts on what might
be wrong and if it's an easy fix (e.g. cleaning contacts, or whatever)
or best taken to the dump. TIA for any opinions.

Compressor is jammed and causes the thermal breaker to trip then a delay
while it cools then it repeats.
Its dead, take it to the dump.

Is it just humming, or does it sound as the compressor motor is actually
running. When my fridge did this, I found the starting relay was sticking. I
bought a new one (solid state) and it has been fine ever since. Costs about
$20.

No, it sounds like it's running, not jammed. I'll look at the relay
again, maybe that's it. Pardon my ignorance (I've worked on electric
motors, but not refrigerator/freezer compressors) but is there a motor
inside the "sealed football" and why is it sealed up? Seems like it
could be made much more serviceable if the motor and compressor pump
were separate. Again pardon my ignorance--I only have a doctorate in
aerospace engineering, not refrigeration mechanics! TIA.

I believe the system is hermetically sealed to eliminate a possible leak. If
you have an external motor, it's kinetic energy will have to be transferred
somehow from outside the compressor pump: generally a shaft.
A magnetic-drive system is feasible, but not practical as far as expense
IMO; especially since the hermetically sealed system is tried and true. They
generally don't need servicing and are 'cheap' enough to replace if
absolutely necessary.
