So I have a bard unit that trips on low pressure, when it runs for only a minute, compressor has a chatter inside, relatively quite, 410a, 200 psi high side, suction goes up then drops below 40 after a minute. Amp draw is 5,5,7 and fla is 12, it’s fixed meter with no signs of frost at liquid dryer or metering device, I guess the question is how can you really tell if it’s only restriction or if it’s now restriction as well as a compressor mechanical failure, compressor olms out were correct thanks
