[MBZ] AC machines
You recall my old robinair AC machine was giving me an error, and called local service center who wanted $180 to look at it, then parts etc. I just bought a 1 year old new machine. Messed with the old one some more and figured it had to be one of the pressure transducers. When powered on it shows low pressure error. Unplugging the connector to the transducer the error would go away. When trying to do a recovery the display would always show 31inhg. At the end when trying to do an oil drain it would fail. I then figured if the transducer was bad, it would not know if the was draining or not. Looking up the part number I found the new transducers listed for sale for about $160 each off the robinair part number. These apparently are supplied by a different manufacturer than original as they look different. I then used the photo of the robinair part to get the manufacturer and part number, did a search and turned up the same transducer for $27 each. Ordered 2, replaced both of them to be sure and it’s now working fine. No errors, does a recovery and oil drain just fine. Since I already bought a newer machine I will probably put the old one up for sale as I don’t think I really need 2 of them do I?

Re: [MBZ] AC Machines
I'd hope that one of the things the diagnostic will tell you is an overall condition of the machine. If they say "this thing is basically just worn out" then you can buy the other one and keep the old one for parts.

Re: [MBZ] AC Machines
If course the icing on the cake is I need to do a replacement AC compressor on my 99 later this week. I messed with the machine a bit and did a recovery on the car and the machine did not seem to vent refrigerant but claims in only recovered about a quarter of a lb. I’m pretty certain it was more than that. After recovering it still shows 0 lbs in the internal tank. So not sure what the deal is. Anyway I’m sure I can use it to evacuate and charge the car after the repair then maybe take it down to the shop.

Re: [MBZ] AC Machines
This machine has 2 pressure transducers one for the low side and one for accumulator. When I switch the connectors between the 2 the error changes to accumulator pressure error so to me that tells me the low pressure one is bad. If I leave the connections disconnected I get no error. The bigger problem is why it’s venting refrigerant. I suppose I could pay the diagnostic fee and see what I am looking at. Just afraid even if I get it fixed then something else goes wrong.

Like Allen said, money is time - give them the money to fix it, and spend your time doing something you really want to do instead of messing with that machine.

Re: [MBZ] AC Machines
If it were me and I trusted the shop I would probably pay the $180 for the diagnostic. Once you know what's wrong, you can decide whether to have them repair it, do it yourself, or replace it. Otherwise it's a careful, deliberate process of testing and elimination to figure out what is wrong and repair it. What is your time worth?

[MBZ] AC Machines
I have a Robinair 34788 fully automatic machine that I have had for about 4 or so years now. Nearest I can tell it is probably 10-15 years old, not sure. Per the menu look like it has has around 2600 lbs ran thru it. Not sure if that is a lot or not for these machines. Anyway, last year it got to where it was throwing a low pressure error when you turn it on, then gives an oil drain error when doing a recovery. Several times it has ended up venting all of its stored R134 thru the vacuum vent line into the oil drain bottle. I also suspect the ball valves on top of the internal tank are leaking. I am betting the low pressure error is the low pressure transducer. I also tested the solenoids and they all appear to work so I am thinking the oil drain error could be the circuit board. When it is supposed to be doing an oil drain it never even opens the solenoid. Called a local service place for these and if they come here its $250 for the drive plus $180 for the diagnostic, or I can take it to Tulsa and just pay the $180, then pay whatever labor for the repairs plus parts. Assuming it needs all 3 ball valves those are around $60 each. The transducer is around $150 to $180 depending on the website. Circuit board is about $350. So if it actually needs all this I would probably be looking at a grand to fix this machine. That does not factor in any additional labor. I would always just order the transducer and see if that fixes the rest of the problems (which I am not hopeful of), or pay the $180 to see what is wrong and what it would cost to fix it. I am however considering just buying a newer machine. There is one exactly like mine but appears to have been used a lot less and includes a 30lb cylinder: https://www.facebook.com/marketplace/item/5143233472435476/?ref=search&referral_code=marketplace_search&referral_story_type=post&tracking=browse_serp%3Adc0e9849-915e-40a4-b3d5-28817f9adfa7 Also looking at these: https://www.facebook.com/marketplace/item/965256667454473?ref=search&referral_code=marketplace_search&referral_story_type=post&tracking=browse_serp%3Adc0e9849-915e-40a4-b3d5-28817f9adfa7 https://www.facebook.com/marketplace/item/274691608128011?ref=search&referral_code=marketplace_search&referral_story_type=post&tracking=browse_serp%3Adc0e9849-915e-40a4-b3d5-28817f9adfa7 https://www.facebook.com/marketplace/item/698606498164730/?ref=saved&referral_code=null I know these are a lot of money but I actually do quite a bit of AC work for my own fleet of cars and projects.
