With all this talk of air conditioning I thought I should report my first impressions of the Atwood air conditioner I bought from Jim K some months ago. It cools very well and the Onan never even begins to strain. The air flow seems very good - lots forward and back. My only complaint is the control panel is a flip-down affair that faces the back of the coach when down. My fingers just aren’t well suited to flipping that thing down, it too close to my eyes to focus on what I’m doing, and if it’s down I inevitably smack my head into it. It does have a little hand held remote control that I believe works from the front as well as the back, though I’ve not used it extensively.
Please don’t take this as a complaint! My old air conditioner had analog dials and rotary switches - this is an improvement! And it’s core function, cooling the coach, it does very well. It’s quieter than my old Intermatic unit, though the old one was low-profile and this is full sized.
The installation was straight-forward and without issues.
Count me as a satisfied customer.

Billy Massy has the same unit, but it stops for few seconds when the temp
is reached then goes back on.
After some run around, I forced our supplier to send another new unit and
return the defective.
I'll probably get hit for half of the freight, but in my book, one needs
to know that when you run a business, you need to absorb these costs, or
not be in business.

I'd like to ask you about the control of your unit, Larry. I installed on
a month or so back. It's great and I love the fact that it dials back the
fan speed based on how close it is to the set point. It's very quite on
low speed.
BUT
When it does reach setpoint, after a while, I guess when the compressor
needs to come back on, it completely stops. Goes dead quite for a couple
of seconds, then the compressor starts up and at the same time the fan
comes on high speed. This is alright during the day, but when asleep it
jolts us out of bed. Just can't sleep with it. It even does it when not
in auto mode. We just have to shut it off and depend on the vent.
Have you had any similar issues? I know there is at least one other person
in the Classics with the same experience.

bdub,
I wish I had some brilliant insight that could explain or fix this situation. I’ve only run the air conditioner on manual modes and never let the newfangled computer tell me what it needs to do. Jim K talked to me about this very behavior and I could offer no similar experience.
I do feel that its cooling is very good as enhanced by good airflow.

Thank for your experience, Larry. My unit does the "turn off, turn on High" dance every 5 minutes or so even in manual fan mode no matter which speed is chosen when the compressor needs to restart.
I don't know anything about how these work, but I'm thinking it nearly has to be in the little flip down control module. I think there's no other brains in the outside unit. If I could just get them to send me another one to try it would be so much easier than the whole blasted unit.
Has anyone else had any experience with the new Atwood 15kbtu Roof A/Cs?

I am that other guy experiencing the same performance on my 15.5k atwood as Billy. I do not use it in Auto mode, usually just cool, and fan on low. but it does cycle, stop, and fans/compressor kicks in and out. pretty busy. I have not really paid a huge amount of attention to exacly what it might be trying to do, but I am sure it is the same as Billy's from what he describes.
I just thought it was normal operation, But Billy stated that atwood service told him something was odd. so I am curious how others are operating?
I am personally a very happy customer with the atwood. I went from an original duo therm, to this atwood, and the difference is amazing. This atwood draws very little power, both the onan, and a honda 3000, did not flinch when the A/C comes on and off. It has not been a really hot season here, but so far the front A/C has been able to easily keep up with keeping the coach at 70 degrees, and the hotest outside temps I have used it in were about 90 out. I still have an original A/C in the rear of the coach, but have not needed to turn it on.
I used the heat pump feature on it, one weekend and it ran overnight and kept the coach at 68-69 degrees all night when outside temps dropped to about 50.
monday morning, it was not super hot out, but was humid, and it has a "dry" mode. I ran that, and I think it really helped with the humidity level without dropping the temps in the coach. I only ran that mode for an hour.
But as Billy mentioned, It seems to be a really busy machine, it kicks stuff on and off, and does alot of cycling. I thought that was normal, and part of how it was being "efficient". It is alot louder doing that on the heat pump mode, then the cooling mode. It is so much quieter then the original A/C unit, I have been fine and gotten used to that cycling pretty quick.
I have not had a chance to complete test the power consumption. It does not even make the onan flinch, and the honda 3000 I tried it on, did not really notice it at all. I ran it one whole weekend on a a 25 foot 12-2 cord(hooked to my 15' 50 amp cord attached to the coach), and the cord did not get hot at all. I ran it on a 15 amp outlet at home with that same cord for about an hour, and same results.
I have a line on a dometic LW3000plus (2400 watt running/2800 watt surge) watt generator I might buy on thursday night. I am pretty sure that will run the A/C. I do hope to test it on a honda 2000 soon. I am usually not one to think about buying a non honda or yamaha generator, but this one is at a price I can't pass up.

My Atwood is doing the same cycling as Bdub's, in every mode. According to reviews the fan is suppose to run at all times, no cycling on and off. Other than this I love their product. For the taller folks (probably 6'1" and above), get the ceiling mount with the remote controller and then the flip down mode panel will not bump your head.

IF you can watch the voltage at the AC unit there may be a voltage sag
when the compressor starts

I am arranging to have a new one to replace the defective one N/C as soon
as we get all the info. to the warehouse.
Rest of you that aquired one that is misbehaving should see if you can get
them to do the same for you. Good luck.

The sample speed on the Fluke probably isn't quick enough to pick up the starting surge, particularly if it's small. Get an analog with a 20A scale and you'll see it. You still won't see the true amount, you'd likely need a storage scope for that. But, empirically, it's so small and so quick, the Onan inetia holds it up, so who really cares?
And remember, "If it works, it's a fluke!"

I have two of the New Atwood 15KBTU Heat Pump units, one on each coach. First, I think you can you can change the direction of the drop-down control panel by dropping the plenum and rotating it (the entire plenum) 180. That also puts more cooled air to the rear. Like I said "I Think" you can. When I was doing the work below it seemed like you could change the direction of the plenum. I was looking at this as internally one vent seems larger then the other and maybe wanted to rotate it to blow more air to the rear but I did not try it yet. Check it out
Next, both my units were cycling about every 5 min. Would cool down to the set temp and the compressor would shut down until the inside temp went back to ambient and then cool down and repeat the cycle. Called Atwood customer service and was told "It appears there may warm intake air and cooled exhaust air mixing in the plenum. Check the connections between items 3, 4 & 5 to assure there are not gaps". (items from owners manual picture). I did that and it appeared that the installer did not line up the plenum correctly with the cold air duct therefore it was mixing the cooled air with the intake air. I lined it up carefully and no more problems. Both units were installed by an Atwood Dealer, one in Las Vegas and the other one in Calif. and both made the same mistake. The ceiling plenum can be misaligned by just 1/4 inch and it will cause a problem. Now they both work great!

Thanks for your response, George.
The plenum is not reversible as the outlet is closer to the rear of the
unit, matching that of the plenum. There doesn't appear to be any blockage
on either side that would make more air come out either end. Registers on
both ends are identical.
The custom cut connecting duct must be seated correctly for it to close up
all the way. If it is too long, it will not come together. If it is long
enough and misaligned, it will not come together. If it is too short, you
got problems and one more chance to get it right.
I did take mine down one time to install ceiling material and made sure a
second time that it was installed correctly. The extension duct is just
the right length and is a slip fit over the adapters on both ends.

I was able to get hold of a tech at Atwood today. I explained the cycling problem to him. His guess was possible circuit board failure. I was under the impression there was only one circuit board (inside the temp controller flip down panel). He said there is also a second circuit board in the upper main unit. Not wanting to wrestle the A/C off the coach again, I ask him what was the easiest solution from here. He said just to take it to any Atwood service center and they could fix it there under warranty. Well, now we will see how good their warranty program is........

The sample speed on the Fluke probably isn't quick enough to pick up the starting surge, particularly if it's small. Get an analog with a 20A scale and you'll see it. You still won't see the true amount, you'd likely need a storage scope for that. But, empirically, it's so small and so quick, the Onan inetia holds it up, so who really cares?
And remember, "If it works, it's a fluke!"

Johnny,
Right on most counts, but if he can search up either a "Flying Bar" 70 series or a 80 series Flukes, that bar graph will see the spike as it updates 20/sec. The 80s also have a peak capture that I use for starter currents all the time.

True dat - but expensive. I do like the peak hold. We bought them because they measure true RMS, necessary in my field of endeavor. And used a 260 (analog) for tuning.

Scott,
Double Trouble had a Dometic 13,500 BTU unit with an out of balance fan (shipping damage) that the original seller and FedEx
declined to cover so I took it to Channelview RV for repair. I didn't tell them that it was damaged in shipping.
I set up an appointment with them explaining what the problem was and they had a spare fan assembly in stock. They troubleshot the
unit, confirmed it was the fan, contacted Dometic, got the OK to replace it under warranty and did so while I waited. I drove Double
Trouble back to it's storage facility in Humble when they were done several hours later.
Regards,
Rob M.
