22 to 23 suction 125 to 150 on head
45#
12 psi
Using a set of a/c gauges put the blue hose on the low side (suction side) and the red hose on the high side (discharge side) to first check the pressures..... Add freon if needed and keep the pressures as follows.. low side readings between 30 to 40psi and the high side between 200 to 250psi depending on the outside temperature…………….
model ebfsa4-1b is 4.8 oz r143a
low side 25 psi high side 125 psi
low 50 to 60 and high 250 to 300
If the pressures are always equal running, the compressor is bad and would need replaced
Altimiters work with pressure. Different pressures create different readings
Did you do the air condition service yourself? If so did you add proper amount of 134a and compressor oil? What are the gauge readings on the hi and low pressure sides? (and include outdoor temp on the day you take readings)
It depends on the RPM at Idle speed your low side apr.. 40 and High side at about 150 at 2000 RPM LOW 22 High 230 if high is over 250 there is to much 134A in system at a amibent temp. of 70 degrees F. RPM and outside temp effects readings.
Evaporator temp should be 15 Degrees. Gauge pressure should be around 15psig
High Pressures is the wrong answer. The correct asswer would be cooler tempeture.
