The 240v Dometic model B3200 roof-Top heat pump operates the fan and makes. Noise like the pump starts but no heating or cooling comes from the vents. When switching off the cooling it makes the swoosh sound like before but only blows air. Any tips or ideas on how to trouble shoot? Thanks
Like so many other caravan owners I have a Suburban SW6DEA gas hot water system in my caravan. I used it once successfully about 3 years ago and then on every successive trip I did so much swimming at public pools that I would shower there and have therefore not tried to use it again until a couple of weeks...
