Working on TWA060D300A1 with TWE060D with TXV. Air handler running, 150 psi head, over 100psi suction(65 degree). Indoor, 65wb, 75 degrees, outside temp 68.
TXV bulb is wrapped and mounted at 3 oclock, outside air to A/H closed off. Not a drop of condensate on the coil. The liquid line temp varies from 74 to 80 depending on which device I measure the temp with. Any ideas on the issue here. R22 charge doesn't seem to be the issue. There was a gaping hole in the return duct cut by someone at one time but this is closed down. Coil inside does not look plugged from a return side visual. Any ideas?
