Gary


I worked for 3 heavy truck ac manufacturers in sales, one for 25 years. Early on, I did a brief stint at Evans Products, the supplier of our units.
Happy to assist but I like to avoid taking responsibility for other peoples rigs! Besides my arms are no longer than yours to reach that low side fitting! Lol

If the clutch wonít engage because of no refrigerant in the system, hook up your low side and add the first can of refrigerant. It will empty the entire can without starting the vehicle. The pressure in the can is enough. The low side switch is set to disengage at around 28 lbs (itís located on the high side of the system) so the first canís pressure is more than enough to engage the clutch.

Will give that a try. I did have the engine running and ac on when I tried the first time. Not sure where the low-pressure switch is located or how to short it so hope by getting a can into the system it will allow it to engage the clutch. Thanks

There is no reason to short the switch unless it is to test to see if the switch is bad, which it very seldom is. If it doesnít engage when you added the first can, something else is wrong! The other issue is if it is completely out of refrigerant, you have a pretty big leak.

Hope this helps

Open your generator drawer. Per Entegra service the both valves should be visible. My red valve was to the right of center and low on the firewall and was easily found. I found my blue valve by feel at the center of the firewall about 18 inches above center. Once I found it access was easy.

If you are topping off your refrigerant, I recommend using AC Pro. After attaching the refrigerant can hose turn your dash temperature dial down all the way, press the dash AC button to on, and start filling. Make sure your compressor is turning and engaged. The easiest thing to do is to use a temperature gun to monitor the dash temperature. When you read around 50 degrees from your vent you are can stop adding refrigerant.

I had to replace my compressor, which also depleted my refrigerant. I purchased a manifold, purchased a vacuum pump and fittings, and charged the system on my own. I did this because local shops charged $450 and I could purchase the equipment and charge my system for around $250, plus I had the gear in case I needed to charge a car or home AC. Itís an involved process and should be attempted only if you have the confidence to follow the procedures. I found those procedures online.

Now you can go into retail repair business.... Nice job! You can almost always save a bunch of money and do as good a job as the dealer or repair facility, but most people don't want to invest in all the equipment.

The next time I'm in Box Elder, maybe I can pay you to service my coach....
My dash AC is never working correctly.

Hopefully success

Thanks to all of the responses I think that I got the system charged. The AC temp from the vent is now 60 degrees. Now a beach bum suggestion to add a can without the engine running seems to have done the trick to get the compressor to engage. Steve's pictures and Chuck help in locating the low-pressure point got the ball rolling.

One thing I noticed is that the gauge stopped reading anything at the point the can was almost empty so I just stopped when the temp reached 61. Not sure how 14 oz of 134A converts to lbs to get to the 2.5 lbs recommended. I guess if I knew how to use a real gauge set I would buy one. ;-)

Thanks to all for the assist...

One thing that might helps others, and I am far from the expert. It was Nowabeachbum that helped me with my 14 when I was chasing the gauge all over trying to figure out where the full mark was.
When my 19 was new and again on the 21, I checked both units with my Walmart gauge and marked where full was on the gauge. The 19 and the 21 were both at the same mark. At least if I have to charge my AC, I know where the target mark is this time. Glad you got yours working.

By far the simplest way to recharge a system is start with an empty one. If there was nothing in it and you need 2.5lbs, add 3 14oz cans which is about 2.6 lbs(16 oz in a pound). If you are starting with a system which has some refrigerant in it, but you know it to be low, add a little at a time and watch the duct temp. I use an dial round faced thermometer that is always sitting in my center duct. Work in a protected area, avoiding the sun because heat load on the coach will hurt your readings. I did mine in a garage. You are looking for around 50 degrees at the duct maybe less on max air and high fan. If I had 60 degrees, I would add another 1/2 can and then watch to see if the temperature drops. If It does, I would add a little and watch it again. And so on til it stops going down.
Slow and patient are the watch words. Also Iím not sure how gospel 2.5 lbs is because I added 3.5 cans to mine and got 48 degrees. That is not to say everyone should start adding refrigerant, that was just my latest experience. Capacity on these things is not an exact science!

Gary, I've followed the same approach on our 2018 Cornerstone.

A couple of years after taking delivery the dash AC wasn't cooling as effectively as it had before. Looked at the compressor and saw some minor oil fogging around one of the hose ends where it connected to the compressor. In other words, a small leak.

Would have gladly paid someone fairly serious money to fix it, but by that time I was aware of several Entegra owners with the same issue who paid fairly serious money to have it fixed, only to have the same problem come back not long after the repair work was performed. I may not be the sharpest knife in the drawer, but paying good money for a fix that doesn't last didn't strike me as the best alternative.

Went to my local high-tech auto supply store (aka Walmart) and purchased two or three cans of refrigerant and a simple AC recharge kit like the one in the image below. Total cost was about $35. As you know, even a marginally competent AC shop would charge more than that to say Good Morning.

I've used the kit a number of times and learned the best approach is what you described; i.e., Sneak Up On It. Put a dial thermometer in the center AC outlet on the dash and have a Senior AC Recharge Specialist (aka Amy) watch the thermometer while I add refrigerant to the system.

I learned early on that you need to stop when things are looking pretty good, because if you keep adding refrigerant that nice cool air coming out of the AC outlet will start getting warmer.

Fairly simple procedure once you get used to it.
