I think your problem may be a burned-out heating element, GHD recalled 8500 units just before last christmas because of this because it actualy started house fires, beleive it or not this is actualy a manufacturing flaw with GHD and you are entitled to your full money back guarantee even if your warranty is out of date, once you have the model and serial number of your unit you are ok.
