Amarin, you might be on to something. It was only 80 yesterday, but static low side pressure was 100, while running at idle it dropped to 30. Increasing the rpms to 1500 dropped it to 25 but the compressor stayed on. Maybe my pressostat or gauge is slightly off. If the orifice tube was blocked as you say, would that explain the high pressure in front of it triggering the low speed fan as well as the rapid cycling you also attributed to it?

Many thanks
Alex
