Anyone have any experience with reverse cycle heating systems? My forward cabin heating unit is sending a fault code to the control panel. Both the aft and galley units are working just fine but I had company this past weekend and figured out there was a problem. I have not done any diagnosis on my side yet but I figured I would write the forum cause you all have always provided me with awesome advice. The A/C worked fine this summer in the forward cabin but heat is the problem.
It's all Good
