404 flashing b4 TXV
cornellius xrc1444 machine, machine has run fine for three years, low production lately, quick inspection found pressure switch at condenser was bad, (would not close swith on pressure rise and stay out), replaced, ran fine for two weeks and now customer states low production, checked condenser fan and running fine, line set very hot and no "heat" pulling through condenser. i am thinking the 404 is flashing before txv, but why and why no heat off condenser?????
thanks in advance
