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.
