What to do if the oil recovery fails during the automatic cycle in MAHLE Service Equipment?
If you're unable to recover oil during the automatic cycle, it could be due to the oil loading cell being out of calibration or defective. Try calibrating the exhausted oil scales. If the issue persists, consider replacing the oil loading cell.
Why is there a refrigerant leak from the oil container during recovery with MAHLE ACX480 Service Equipment?
A refrigerant leak from the exhausted oil container during the recovery phase, despite a negative leak test, may be due to dirt inside the Oil discharge solenoid valve. Suggested solutions: 1. Clean the solenoid valve. 2. Check the gasket. 3. Calibrate the pressure sensor.
