I had a 1402 in my previous coach an HR and it was in a slide. They stopped making this model by 2011...I had two issues, one a defroster thing when the coil on the pan somehow got split....pain the in rear to replace...but noticed that that fridge and freezer would heat up when winds would keep the air inside the slide and blow back the hot air...I bypassed the fans and had them run on a switch, which helped but did not get rid of the problem. If your 1402 is in a slide with a top slide vent...that might be it..
