Good day,
Replaced the entire AC system (evaparator, compressor and condenser) added refrigerant. Still no cooling. Any suggestions would be welcomed. Thanks!

First, did you put the appropriate amount of the correct oil in the new parts?

How much refrigerant did you put in the system?

Did you put a new orifice tube in the system?

First, did you put the appropriate amount of the correct oil in the new parts? Yes, unit came with 6 oz, added 2

How much refrigerant did you put in the system? Using Pro AC 45 psi

Did you put a new orifice tube in the system?
Did not install new orifice.
Thank you for the reply

 

[Fred Kiehl]

The orifice tube goes in the metal line at the connection to the condenser. The blade end goes in first.

No orifice tube: AC won't work right and will go to an early grave.

Will install in am..thanks

I read this statement the wrong way the first time I looked at it. I missed the colon. I now assume you wanted to say:
With no orifice tube in the system the A/C won't work right and will go to an early grave.

What happens when:

• engine running
• AC on
• disconnect connector on the accumulator
• use a wire and short across that connector

Compressor should engage. Saying that, you didn't tell us in the original post if the compressor was actually engaging, you just said "not cooling". We need more info. Did you vacuum the system before filling? Add the correct amount of PAG for each replaced component?

Installed the Orifice, refill to 45 psi with refrigerant, engine on, ac up high (max), compressor coming on going off..no cooling yet. unplugged the accumultor switch..compressor stop coming on..still no cooling...Thanks

A/C service is a procedure that needs to be done very systemically. If you just throw it all together and hope it will work, you have set yourself up for a failure. Not saying you did that, but you need to know every step thoroughly before you start.

totally understand what you are saying...did the research and got the right parts...will have a tech look at it..Thanks

You didn't say anything about new lines or O-rings either. Did you flush the system before putting new parts on? You might have to start over from scratch. Think everything though. You can't rush these jobs. It will never come out good.

Yes, of course, new o-rings all around...did not flush the system prior to installation of new parts. great recommendations...

45psi is not a magic number, you need to go pounds of refrigerant

 

[Fred Kiehl]

It requires a total of about 40 ounces of refrigerant.

Did I miss where you evacuated the system ?

That's what I was wondering about. Might need to purge the air from the system.

 

[sherlock9c1]

You really need gauges on both sides of the system to see what it's doing. I don't know why stores sell those kits with only the low side gauge. It is utterly useless.

 

[stonebreaker]

Well, if you don't care about global warming, you can vent the low side with a screwdriver for about 10-15 seconds while the AC is running. That will vent most of the air out of the system.

If the system was just charged without being vacuumed first, the dessicant is probably pretty loaded with moisture at this point. Vacuuming it for a minimum of 30 minutes (preferably an hour or two) would do a better job drying out the dessicant).
