Sorry David, yes I meant the orifice tube. I am going to replace my low pressure switch and see what happens. Thanks again, -Alex "You're going to have to do better than this. I do not know of what part you are reffering to when you say "thermistor" in reference to the evaporator coil. Perhaps you mean "Orifice tube"? The 2 main reasons for the A/C not to cycle is: 1 improper amount of refrigerent 2 defective or out-of-adjustment low pressure switch. Of course many other things can cause the system to not cycle. Dirty coils or not enough airflow can also affect the cycling. Replacing the orifice tube is "a big deal". You have to remove the refrigerent.
