Our Robinair a/c recovery machine has power to the switch, but will not power up at all, any ideas?

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.

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.

Robinair seems to no longer support older models such as you're machine as it was built in 1991-2 and sadly it seem's not many people have kept there old manual.

if you have no power to the compressor then you know what the problem is... you are not getting power where it needs to go...
Sounds like a contactor or relay problem.
Trace the wires backwards with your meter till you find where the power is stopping at.
The you should be able to figure out what the ultimate problem is...

This is a common problrm of Robinair 34700Z / 347002k & 347112k series machine.so don't worry just do the following :- 1# Verify the ISV tank is not overfilled.if full,remove refrigerant manually from tank. 2# Verify if there is high pressure in the tank.Purge excess air from the tank manually.( Open air purge hose from the tank,then press tank valve as needed) 3#Check the high pressure switch for proper operation,if not then replace high pressure switch.Hope this will solve your problem, if so please vot for it
