Guest Gary Posted March 19, 2005 Share Posted March 19, 2005 Hi I have a roof mounted AC unit,it works fine on cooling,but when I turn to heat it runs for about 3/4 mins(just as the heat starts to come through)then throws the RCD unit in the consumer unit. Anyone got any ideas please. Link to comment Share on other sites More sharing options...
Guest Clive Posted March 19, 2005 Share Posted March 19, 2005 Sounds to me like some leakage to earth associated with the heating side of it. Have you checked that its dry underneath that big cover? Link to comment Share on other sites More sharing options...
Guest Docted Posted March 21, 2005 Share Posted March 21, 2005 Could be wired into the wrong circuit in the RCD Gary and the heat element is too much current and blows the RCD. Docted Link to comment Share on other sites More sharing options...
