You may have one of those problem. 1# Machine is showing wrong weight. if so you need to re-calibrate the scale. 2# Check tank ''LIQUID'' hose is connected (one of three hose on the tank which is marked with -Vapor - Air purge - Liquid ) to the tank properly, make sure it is not loss or over tight. Hope this will help you to solve the problem. if so, please vote for it. wish you good luck!

Mod 34800-2k will not refill more than 2 lbs of r134


It is probably to warm. Are you filling it with liquid by turning the tank upsidedown.

34700z only charges about .5 lbs to 1.0lbs, asks to start engine to help draw freon in. still won't charge any more. where should i start


The machine requires a min amout of 6lbs to even charge. but if you are showing any amout charging it is not the machine its self. you are looking at may be bad hoses or couplers. it is common in the winter months to have charge issues if the unit is not above 70 degrees F. dont forget there are cars/trucks out there that no matter how hard you try you can not complete a charge on the high side and you must switch over to a low side charge

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!

My 34700z will tell me i have 2 or 3 lbs of freon but when i try to charge even 1/2 it will say insuffecent. how do i reset the machine to get a true reading? thanks


Your machine sound like normal to me! For charging to the vehical you should have minimum 3.30 lbs of refrigerant on ISV tank. However if you wish to re-calibrate the scal,please check with my other solution where i post detail information about scale calibration.
I wish this will help you to solve the problem.

Machine will not read scale or does not weigh freon . will evacuate but will not charge says tank needs fill but will not fill either


Most robinair units require the filter to be changed every so many uses. If the filter is not been changed, the unit will not work.

I have a Robinair 34134Z It will not recover freon It has 22HG suction The solenoid is working properly Auto freon goes back through the valves to the solenoid and the suction pulls 22 hg at the solenoid...


Please check the following: 1# Check the recovered amount of refrigerant since the last filter change(Max.filter cap.150 LBS/68 KG).If more then this you must change spin-on filter & vacuum pump oil.2# Check with vacuum gauge on compressor test(During compressor running) port & make sure it has 13"HG of suction,If suction less then 13''HG then you have to replace the compressor.3# Check all tank hose (Vaipor,Air purge & Liquid) is connected on the ISV tank quick seal.(Do not over tight).Hope this will solve your problem.
