As stated above, the trailer has a 1 year warranty on "everything"... During that year, Keystone will repair anything that's covered and then file the documentation with the specific appliance manufacturer (for you). After the Keystone 1 year warranty, there is usually a appliance manufacturer warranty that will still cover the appliances and some of the other components. Keystone will not process any documentation for you after the year (it's explained in detail in your Keystone Owner's Manual in the warranty section).

In the situation you're in, Dometic air conditioners have a 2 year warranty. You need to either have a Dometic authorized service center/serviceman do the repairs (testing and replacement/repair as directed by Dometic) or have your dealership do the repair as they are a Dometic authorized service center.

If your RV repairman is in the process of getting his Dometic certification, he should be able to do the repair for you after his paperwork is in order.

Don't be concerned with June 7th. The only change will be that you or your repairman will have to deal with Dometic rather than with Keystone. You're A/C is still covered until June 7, 2018.
