What would cause this new compressor failure

In July I replaced comp, condenser in my Honda Pilot and it the compressor burned up after a week.(just got done replacing entire system). I assumed since I didn’t flush the system or replace expansion valves there was metal left in the system from original compressor. Just went out today and tore into the replacement denso and didn’t see much sign of metal particulate. The thing did obviously have a complete meltdown however. What did I do wrong? I don’t want to make the same mistake. Sorry img linking won’t work.

Overcharged? Airflow across the condenser? Non condensables Was the compressor new or rebuilt? What was the clutch gap on replacement comprtessor? OIl in system and how much?

Don’t believe it was overcharged, new compressor, 4 oz oil, I remember checking the gap and thought it was good to go, guess not

Looks like a clutch failure, the compressor may be ok.

High head pressures can cause a clutch to fail, but there are usually other factors that contribute.

Was this an aftermarket compressor?

Clutches perform best when they have been burnished a bit, and are dry & clean.

The fact that you had a compressor fail & replaced it without cleaning up the system is the first place to look. It is possible to plug up a condenser with debris which will put a huge load on the new compressor.
