These jokes are bad enough to make Todd blanch.

If you've ever noticed that the compressor seems to come on with a bit of a growl and is briefly running too slow, but then it speeds up and gets quieter, you're hearing the effect of the start winding briefly fighting the run winding before it cuts out and the compressor reaches full speed.

Now, I had heard reports that the PTC thermistors these fridges came with were failing. And if they fail open, then when the compressor receives power it will stall. The run winding will be passing current but the rotor doesn't move, and a stalled motor consumes a lot of power and gets very hot.

Now since a fridge compressor can stall if the power is briefly interrupted and then re-applied (the high-side pressure will physically stop the rotor from moving even with working start components) there's a second component called the overload which is basically a self-resetting circuit breaker.
