rdickinson Posted February 19, 2017 Report Share Posted February 19, 2017 There are 2 ac/heatpumps on the roof, a 15k at the rear and 13.5 at the front of the trailer. The rear seems to be working outside ground temp in the shade is about 80f temp of inside of duct 49-45f taken with laser gun condensation on ceiling duct flange roof unit air exhaust 110f condensation running off roof. A little over a gallon in 18hrs. Fwd 13.5 air temp 75 out of ceiling duct temp of ceiling adjacent to grill 78 roof unit exhaust air temp 95 no condensation on inside ceiling duct flange. no condensation running off roof. They both used to start up in 3 stages, a few minutes when temps were set, then some part of them would start then a minute or more later the second part or stage would start up. Rear 15k still goes thru time delay then a 2 stage start up. Front 13.5 still has time delay then starts up but doesn't seem to cool. The front one seems to blow the breaker the odd time for some time. Any diagnosis or recommendations? Thanks Link to comment Share on other sites More sharing options...
