Q: A/C system failure

asked by on July 08, 2016

My air conditioning system output 2 weeks ago was 47 Fahrenheit, and the system failed. Was it possible that the hot air output with the A/C Clutch Engaged and the A/C Panel switch ON might have caused this failure? The Clutch should NOT be engaged. The measured system static pressure was "0" with the gauge was set on high/low ports. I suspect that maybe the air conditioner switch and/or the compressor was at fault. My compressor was replaced in June 2015, and only one pressure switch with this design is mounted near the compressor. I need some advice please. Thank you.
