George did you ever get it figured out? My main unit has decided to do the same thing. It will get down to set temp and turn off for 2-3 seconds and then back on. It hasn't been doing this until today....GRRR
For anyone having issues of them dying, did you happen to get a picture of the serial number tag on the unit? I was up checking for hail damage (none), and ours say assembled in the USA, and have a 2015 year but no date.
I guess your lucky because mine lasted 1 day. My coach was built in March of 16 and I took possession on May 1, 2016. May 2, 2016 the awning no longer worked. Motor went bad.
Bought myn Cyclone in August, 2015 new but was not IN it until Dec. Found at first use a couple of weeks ago thar living room Dometic a/c not working. It is being replaced this week.
Garage didn't work for me either but dealer says it is working fine now; we'll see.
If you have 3 A/C units in the Cyclone, you can run only 2 at the same time. Which 2 run is controlled by a switch.
Domestic owns Atwood.Should your warranty expire and you have to pay the cost of a new AC consider an Atwood Air Command, a friend who is a retired executive of the RV industry just replace his 2 year old AC with a Atwood Air Command unit. I was inside of the trailer numerous times this past snowbird season and that AC unit made half or less noise then my Dometic unit that was OEM on my Bighorn. Everyone commented on how quiet the unit was. If you look into it you will see that there is a change to the design of the unit which originated in Australia.
If I had money to burn I would yank my unit out and replace it so I wouldn't have to listen to the racket it makes. I have Pulled the shroud on it and checked it to see if there was a reason it was so noisy but it's just the design of the beast.
Hi HooDad,
A number of people have posted about their Dometic Air Conditioners leaking freon which requires replacement of the unit. A few more than once. Reportedly, Dometic moved manufacturing to a new location and the tubing quality suffered. From what we've seen here, they have corrected the problem, but as you say, there may be units like yours that are just now failing.
I believe Dometic has a 2 year warranty on the A/C unit, and if you're past that, I'd suggest calling Dometic Customer Service to discuss how they might help.
Recalls are usually for safety issues. So I wouldn't expect a recall notice on this issue.
I think your Landmark A/C unit was designed to work with your duct system. I doubt you could put an Atwood in its place and expect it to work well. And Dometic uses a proprietary thermostat control system.If you have an original Dometic AC (my Landmark Key Largo has 2 A/Cs but only one is not putting out) and replace with an Atwood can you replace just one or do you have to replace both at the same time and do you have to replace the thermostat controls?
I'm getting ready to have my second A/C replaced due to not cooling. Is there a known problem that should require a recall? If you only use your RV a few weeks a year you may not experience this problem for several years then it will be too late to have the A/C's replaced due to being out of warranty.
