You have a hard starting compressor. To verify, you can get an amp probe and check the current. If I where there, I would get it running and check for high head pressure and measure the run current.
You also could try a lower resistance prc device mentioned in my article "replacing compressor start devices", just put in the fridg search box. You will need a meter to install this.
