A couple suggestions:
1. Check compressor winding resistances and compare to known good
2. Intermittent voltage drop in circuit
3. Saw something like this before, intermittent logic fault in CLO board would cause compressor contactor to chatter severely. Parts laying in compartment as you stated would appear that the chattering got worse than the one I worked on. It was not a pretty sight but I did see it occur. Replaced the CLO and contactor OEM (94 rated amp)
all good. Sounds like a 48DJ, with the 06 semi on the filter access corner side.
Try a new CLO when you replace the CC and double check the OEM recommendation for RLA.

I wanted to install a higher quality (if thats even possible) all I had in a square d was a 40 amp..it only runs about 15 amps +/-, and is properly fused.

Yes I have tested it, worked properly while I was there.

I did think of this too. I just bought my stock about a month ago, time will tell. Although customers dont want to hear that.. Always the techs fault.
