If you do not have 24 volts between Y and C then you either have a thermostat problem or a broken thermostat wire problem. You would need to keep checking for 24 volts between the Y and C wires. Where you stop getting the 24 volts is where the problem is located. How can I detect if the cause of the problem is low pressures (refrigerant charge) and not something like short circuits or other things? Without measuring the pressure is it possible to find out for sure that the safety control is the reason I don’t have 24 on my contactor? Without gauges, it is a guess. If I did not have gauges I would turn both the high voltage and low voltage power off to your unit, cut the two wires that go into the low-pressure switch, strip the wires back, and join the two wires together with a wire nut. Make sure that you leave enough wires sticking out of the low-pressure switch so you can reattach the wires after this test.

The reading you get between your common start and Common run should match the numbers between your start and run. From common to run on my multi meter read 1.2 and from common to start read 2.3. When finish calculating the numbers between the two. 1.2+2.3 = 3.5. That's the reading I received between common run and common start. Next I'm going to calculate the reading between start and run. My Multi meter read between start and run. 3.7. It, usually be one or two off but it is still in the range. That means this is a good compressor.
