2019 expansion valve

'19 F250 diesel, Im about to have to install my 4th expansion valve. The AC just stops blowing cold, Its been changed out by a dealership under warranty twice already, less than 60K miles.

Anyone else experiencing this? What causes expansion valve failure?

Trash clogging them up.
Has there been a compressor failure in the past?

No. The TXV failed very early on (probably less than 10K miles), then again about a year ago (50K miles maybe), now its behaving the same way again.

Perhaps this time I should also replace the receiver/drier/filter?
