You have been talking to an Artificial Intelligence AI Answer Bot ( computer AI Model ) and they never respond back. I am deleting all Sandile's answers. They are wildly generic and are never SPECIFIC to the question asked. I believe I answered your question last night.The section up above is for asking you, the OP for further information before a Fixya Expert commits to an answer. You should be clicking 'Comment' under the answers, not up here.There is no one on the Fixya Expert team that is an expert with Robinair Recovery Units. I have been here since the beginning. Your best bet is to ask Robinair Customer Support as I mentioned last night, or you can ask ask at www.justanswer.com..

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.

The Robinair Cool Tech 34700Z refrigerant recovery/recycle machine is designed to recover and recycle refrigerant from air conditioning and refrigeration systems. If the machine is losing refrigerant during the vacuum cycle, it could be caused by a few different issues. Here are a few possibilities:

1. Leaks in the hoses or fittings: The hoses and fittings on the machine may be leaking refrigerant, causing it to lose pressure during the vacuum cycle. Check for any visible leaks and replace or repair any damaged or worn hoses or fittings.
2. Leaks in the machine: The machine itself may be leaking refrigerant. Check for any visible leaks and replace or repair any damaged or worn parts.
3. Incorrectly set vacuum pressure: The vacuum pressure may be set too high, causing the machine to lose refrigerant during the vacuum cycle. Consult the manual and make sure the pressure is set correctly.
4. Clogged filters: The filters in the machine may be clogged, preventing it from holding a vacuum and causing it to lose refrigerant during the vacuum cycle. Clean or replace the filters.
5. Incorrect vacuum pump oil level: The vacuum pump oil level may be too low, preventing the pump from creating a strong enough vacuum to hold refrigerant. Check and add vacuum pump oil as needed.

It's best to consult the manual or a professional technician for help. They will be able to diagnose the problem and recommend the appropriate course of action. It's important to note that not addressing this issue can cause further damage to the machine, so it's best to have it repaired as soon as possible.

Remove s11 solenoid ?

it is a vacuum pump and not a car so moved to vacuum tools take it back to seller and exchange it or get money back. or bought off "AmaZONED", AND IS REALLY USED JUNK SOLD THERE AS NEW, AND IS NOT.(ENDLESS PAIN THERE) I AVOID THEM LIKE THE PLAGUE NOW, FOR YEARS CAME IN A SEALED BOX WITH FULL INSTUCTIONS AND ITS STRAPPED FOR 240VAC, AND FAIL TO SET IT UP FOR USA WIRING? THAT IS A TOP BRAND FOR AC WORK BUT THEY SELL EXPORT MODELS, AND WHAT IF YOU GO THAT./ SKIPPED STOP 3 TO 7 HERE https://www.manualshelf.com/manual/robinair/15310/manual-english/page-4.html YOUR MODEL IS USA VERSION, SAYS MAKER.

With power off, open the filter & check two 'O' ring of filter is in the right position then replace filter again. Hope this will solve your problem.

You confirm it by how it functions, if it sticks in a mechanical way there is no electrical testing that would be valid. I would just replace both solenoids.
