model ebfsa4-1b is 4.8 oz r143a
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…………….
low side 25 psi high side 125 psi
If the pressures are always equal running, the compressor is bad and would need replaced
The exact psi level of R-134a refrigerant varies depending on the temperature. At 70°F (21°C), the pressure is approximately 75 psi for the low side and around 150 psi for the high side in a typical air conditioning system. Always refer to the pressure-temperature chart specific to R-134a for accurate readings at different temperatures.
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
