Quantity:High (15pcs)+Low (15pcs)=30pcs. - Faulty compressor but make sure its running (in other words is the clutch locking) - Low Revving the engine and having the low side jump to 90 psi and high side drop to 125 psi would indicate a weak or failing compressor. 250 PSI high / 30 PSI low: This pressure usually indicates that there is air inside your system somewhere. My AC stopped working so I checked the compressor and it seemed to be working just fine. 99. b. The low-pressure side, when connected to the gauge, should read less than 100 psi. Due to the difference Or the operation of your compressor is failing and you have to replace it. The high pressure side is the discharge side. Burped yellow line @ the manifold to purge air 12oz can+valve+hose weighed 20. Sequence: 1. 85/2 and 86 are low side (the car is at standstill) At the moment I'm getting low 30's on low pressure side & 40-50's on high pressure side is that about right ? I thought I would be getting 10c or so on low side The low side line of the system will have a larger diameter metal pipe than the high-side. Low side 45 PSI; High side 225 PSI. So, up to 85/1, both are on the compressor. Low pressure or suction side typically varies by equipment. Due to the difference Idle, when guage is not fluctuating - low: about 35 or so, high side about 120. However, if there’s a restriction on the high side I was about 30 PSI low side and the high side was 200 PSI. Turn on the A/C system, and let it run until When I would turn the air conditioner on, the low-pressure then went down to about 45 psi (the high side of being filled) and then slowly began to work it’s The air conditioning compressor acts as the _____ of the system, keeping refrigerant circulating during air conditioning system operation. Therefore in a normal R134a, the low-pressure side What should high side and low side AC pressure be? The system should be about 25 to 30 psi on the low side and 200 to 250 psi on the high side.
