Dometic air con unit making a humming noise
My rooftop air con unit is making a strange humming noise when not in use. only started playing up this weekend.
The system works fine - when you switch it on it blows lovely cool air, but now when I switch it off it makes a low humming noise. only way to stop it is to unplug my mh form the mains
Certainly cant be right - anyone else experienced this type of problem, and has anyone got any suggestions where to get this fixed - not sure how experienced garages are with roof aircon
