Please help.
I have a client with three (3) dunham bush casette airconditioners. Below is the model numbers of one of them:
Indoor CS704M
Outdoor PH24c.
All three units are identical and are showing the same problems, i.e they are not cooling and show the same symptoms which are as follows:
Suction pressure 60 psi
Discharge pressure 150 psi.
Condensor discharge air temp is ambient.
Evapourator discharge air temp is ambient.
From what I can tell, there is no restriction taking place at the evapourator i.e. refrigerant is just circulating through the pipes.
Apparently I am the third tech to work on the units, the other two gave up. The client says the aircons have not worked from day 1.
I just cant believe three AC's in the same area are defective.
I have received no help from Dunham Bush.
