Could’ve been a supply issue, not just the contactor.

High subcooling before a restriction looks identical to TXV overfeeding. If subcooling drops significantly at the condenser outlet vs the TXV inlet you’ve got a restriction in the liquid line.

Pitting and discoloration suggest rising resistance, which can lead to voltage drop under load and intermittent sticking once the contactor warms up. This one’s heading toward failure not there yet, but close.
