The small cover should enclose an overload (black, circle)
and a start relay (looks like... a ... relay).

I found a wiring diagram on the frige metal work.

It shows an overload protect device. The overload and the
start cap are
inside or at least part of the compressor. There is a small
plastic cover on
the side of the compressor, I'll pull it tomorrow and see
what it conceals.
