Hi, my robinair ac375 wonot charge gas, gauge up arrow and down arrow wont move, we done filter and vaccum oil and reset. it is possible to get special way to reset gauge?


mhkamran.jpg Please check Charging solenoid (S3) in Solenoid manifold block, it may need to change solenoid coil or Rebuild. If charging solenoid is OK, then problem can be SCALE or MAIN CIRCUIT BOARD. See if the machine display show default charging weight 90 kg/lbs when you active CHARGE mode. If not then calibrate scale. But if default charging weight is shown then replace MAIN CIRCUIT BOARD. See attached picture to find solenoids. I wish this will help you to solve the problem. If so please vote for it for further assistance. Best of luck!
