There are no bad TXVs, just bad elements and mistaken technicians.

This doesn't apply in only a few instances, such as TXVs that have permanent power elements.
Hem057 , if there is nothing for the comp. to pump, how could the head pressure go up. The system probably has more than enough room to park all the refrigerant in the condenser.

Dave as usual is right on.Powerhead or I bet you gots alot of gummy garbage , or my favorite word for invoicing "debris" in there.

No bad TXVs just misunderstood.
