I have not looked at it today, but I think the start winding is partially shorted. It can't be totally shorted as it has starting torque.
There are two ways a klixon can trip out. If the current is very high (more than 30 amps) the klixon will
trip out within a 100 milliseconds, but it has not heated up much, so it closes in less than 100 milliseconds.
The second way; If the l overload current is around 20 amps, or less , the klixon takes several seconds to trip out and due to it's
higher temperature, it takes up to a minute to turn back on.
Also, in this high current case, the ptc device still has not raised it's resistance to limit the current, so the compressor just oscillates till the pressures
become more equalized.
