Either you have really bad juju or something is seriously wrong with the 120v power where you use the RV. In 20+ years of extensive Rving, 150-190 nights per year in hot climates, I've never had to replace an a/c and have only had two repairs (a circuit board in one and a capacitor in another).

I'm with Gary. Even a 'poor quality' brand/make should do better than that. Maybe the key is the heat pump? Just guessing

Failure 5 and 6 were heat pumps, the other 6 just ac units. Last ac units were Brisk ll air which are rated high. My electrical has been checked on many occasions because of so many failures. All four service centers (Dometic approved) have called the fault on the units and not the rv or service I was using at the time. Like some of you I had great service in the 80ís and 90ís with the unit on my Pace Arrow. Not so on several rvís since 2013

Dometic units have been having lots of problems for the past few years...leaks, burned out compressors, etc.

Are the failures all mechanical, with no corrosion or other factors? Like others in 50 plus years of camping and the last 40 with AC never a failure so hope that trend continues. The last several have been heat pumps as well and the earlier had heat strips.

Older Dometic A/C units were usually good for 10+ years. At some point Dometic moved A/C production overseas and reliability suffered. 2014 to 2016 were some of the worst years. Let's hope they get control over it.

They have also changed the design. Older units had a lot more steel and aluminum and new units have more plastic. The earlier design heat pumps defaulted to heat mode and new units default to cool mode. They have also changed refrigerant version from R-12 to a newer ECO friendly R-410a. Probably lots more.

Ok.... you folks are getting me worried, my 1994 Allegro gas MH still has the original Dometic A/C unit. Been waiting for it to go out one of these days, guess I wont complain if I have to replace it. Glad things were simplier back then!

The older Dometic unit lasted a LONG time. DOn't worry until it stops.

Like everything else quality has gone straight down the toilet. The copper tubing is thinner, he capacitors are made with extremely thin foil and are no longer oil filled, the relays and circuit boards have no silver content and motors and compressors are no longer wound with pure copper wire. Welcome to the 21st century!!!
I purchased a new rig in February and they replaced my center heat pump 4 wees ago.

Tajfish 06-26-2019 08:36 PM

Older units were great. As far as corrosion etc these 8 units failed in the last 6 years. Most did not last a year. And my coach is stored during the winter months.

Tajfish 07-08-2019 04:43 PM

New units are suppose to be here within the hour. :)

That's the reason I bought the 5-year Dometic warranty on both new heat pumps! :thumb::D

Tajfish 07-08-2019 07:03 PM

That the saving grace on these. They are under warranty and will be for 5 years. They were just installed a year ago. The guys are finishing up so are trip is saved. Just wish these units were built better.

Built better? Well, they were!
I have a 10 year old MH with 3 Dometic A/Cs.
One died at age 8, and the other 2 are going strong.
Iím only guessing, but this rig has been busy for all 10 years, which means using them often and hard is good!
