A/C not cooling

Try this chart. Should show up very large if you just click on it. The thermistor controls a couple items to keep the core from icing up, You might be able to run without it but that isn't something I've ever tried as having the core freeze up isn't a good thing.

If it's still icing up it could be a few things. The system is slightly over or under charged. Or the air is very humid and the moisture is the problem. For the over/under charged issue the icing would occur because the refrigerant is lowing the temperature too far in both cases. Sounds strange but that is why the pressures are critical as either side of "correct" will cause similar problems.

It's what we do. Just can be interesting sometimes when a problem just doesn't want to be repaired.

That would do it. The system thinks it's freezing up and shuts down then warms up just enough to work. Thank you for being diligent in tracking the problems. That is the bigger item. Thank you for using 2CarPros.
