Question for those who may know, have not used out new Landmark since its Purchase in Feb. of 2014, while on vacation this past week the main A/C thermostat read E1 and a/c would not work. Called Dometic and they put me in contact with a mobile certified tech for dometic, now this was July 3rd so dealer was not an option, so the tech went up on the roof and determined that Heartland had connected 2 communication cables on the main board and was only utilizing one as the second one was shorted which caused the problem. Now since Dometic did not install the unit nor wire it this becomes a factory defect not a Dometic issue, so do I have any chance of getting back the 176.00 I paid to have the communication cable removed?
