SOURCE: i have a robinair cool

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!

SOURCE: I have a Robinair 34430 that will not charge,

You can do the following :
1# Rebuild/Replace ''charge'' solenoid.
2# Check ''recover'' solenoid is working properly. Repair as need. If recover solenoid is OK, Then you may have to replace the "Compressor".
I hope this will help you to rectify the problem. If so, please vote for solution. Best of Luck!

Robinair 34788NI Excess Tank Weight Error

Yes, that's correct. These are the most common causes for a dryer to have a light that turns on but the machine won't run. It's important to check each of these possible issues to determine the root cause of the problem and fix it accordingly. If you're not comfortable doing the troubleshooting and repair yourself, it's best to seek the help of a professional technician.

How do I purge excess air from tank manually on aRobinair 34788NI

To manually purge excess air from the tank on a Robinair 34788NI, you will need to follow these steps:

1. Connect the recovery machine to the vehicle's A/C system and open the valve on the recovery cylinder.

2. Turn on the recovery machine and let it run until the high-pressure gauge reads about 500 psi.

3. Turn off the recovery machine and close the valve on the recovery cylinder.

4. Disconnect the hose from the recovery cylinder and open the valve on the recovery cylinder to release the pressure.

5. Close the valve on the recovery cylinder and reattach the hose.

6. Turn the recovery machine back on and let it run until the high-pressure gauge reads about 500 psi again.

7. Turn off the recovery machine and close the valve on the recovery cylinder.

This process should help to purge any excess air from the tank. It's important to follow these steps carefully to ensure that the recovery machine is used safely and correctly.
