Hello, what's the outisde air temperature and did you measure the pressures with it at idle speed?
70 degrees outside. and the pressures were measured while at idle
Thanks, ***** ***** be around 35-40 lo and 145-160 hi at that temp. I would suggest replacing the expansion valve, it sounds like it's malfunctioning and causing the low side to go low enough for the low pressure switch to cut out the compressor. I'll post info on how to swap it below.
