Robinair 34288 oil error code 2 - Robinair Measuring Tools & Sensors

The recovery solenoid in the Robinair Cool Tech 34288 Recovery, Recycling, and Recharging machine is an important component that controls the flow of refrigerant during the recovery process. The exact location of the recovery solenoid may vary depending on the specific model and design of the machine, but generally, it is located within the machine's internal components.
Since I don't have real-time access to specific diagrams or current models, I can provide you with general guidance on how to locate the recovery solenoid in a typical recovery machine:
1. **User Manual:** Consult the user manual or technical documentation provided by Robinair for your specific model. These documents often include detailed diagrams and instructions on the machine's components and their locations.
2. **Front Panel:** Many recovery machines have a front panel that provides information about the machine's processes and settings. Look for any labels, indicators, or buttons that might refer to the recovery solenoid. It might be identified as a "recovery valve" or similar term.
3. **Access Panels:** Some machines have access panels or covers that can be removed to reveal the internal components. Refer to the user manual to determine if there's a specific access point to reach the recovery solenoid.
4. **Visual Inspection:** Carefully examine the machine's exterior for any labels, tags, or markings that might indicate the location of the recovery solenoid. It might be accompanied by other components related to the refrigerant recovery process.
5. **Contact Support:** If you're having trouble locating the recovery solenoid or need more specific information, consider reaching out to Robinair's customer support or technical support. They can provide guidance and assistance based on your model.
Remember that refrigerant recovery and handling requires specialized knowledge and training to ensure safety and proper operation. If you're not familiar with the internal components of the machine, it's recommended to seek assistance from a qualified technician or service professional.

To calibrate the scale on Robinair 34288, follow these steps:

1. Turn off the machine and make sure that the scale is empty.
2. Press and hold the "Weight" button for three seconds until "CAL" appears on the display.
3. Place a weight of known mass (such as a 50-pound weight) onto the scale and press the "Weight" button. The display will show the weight that you placed on the scale.
4. Press the "Weight" button again to confirm the weight. The display will show "CAL END" to indicate that the calibration is complete.
5. Remove the weight from the scale and turn the machine back on.

Your Robinair 34288 scale should now be calibrated and ready to use. If you have any issues or concerns, please consult the user manual or contact Robinair customer support.

That image is two dusty things with wires on a 'Robinair Measuring Tools and Sensors' category.

The amount of oil moving with the gas is minimal as it is only what passes the pistons as lubricant that travels with the gas. The receiver dryer catches most of the oil that is moving. New compressors have the correct amount of oil so if you have the need to add oil check what is in the dryer and that will all that you need to add. If the system has excessive oil in it you will experience problems in the tx valve as the oil blocks up the opening.

what is the pressure reading on your guages? if it is below 0 if so the vacuum pump should kick on. if the vacuum pump keeps turning on and off check the software version on the machine if it is not 3.09 or 3.11 the software needs updated contact your local robinair service center. if it is not the software then the recovery solenoid may be sticking closed and will need replaced.

the machine came with a calibration check weight in the menue you can check the calibration. if it fails contact your local service center the machines have to be calibrated with certified weights unlike the older machines.

Not sure what you are doing wrong, but the system is certainly NOT discharged with the low side pressure. Resolve that and you should be good to go.

You need to replace oil drain solenoid

Try with this code-FD32C46B01. I'm sure this will work! Good luck & vote for my solution

There is no Weight in the machine. Machine show Filter weight that you have been recover refrigerant from the vehicles since last filter change! After every 68KG/150LBS of refrigerant recovery you must change the Spin-no filter. The machine ( Model-34788 ) will lock-up when filter capacity reach to 68kg & you will not abel to access the machin till replace new the filter.
When the machine show the filter weight 68kg on screen just press YES key,then add the 10 Digit code of new filter ( Code is stick with evey filter). If the code is accepted then open the old filter & replace new one.Follow the on screen direction to compleat the process.
Note: Do not switch off the machine till compleat the filter change function.
