Hi Inkymart.
Check out the attached as I think despite being for a Alpha 53 the codes and suggested remedies are the same?
Good Luck Grizzly

Had another look around and found this which is for the 75. Ther are other model which have the 75 suffix in their model number . So hopefully this is the correct one?

Hi INKYMART123
If it is the probe your best bet is to measure the resistance of thermister most are about 5k ohms or 10k ohms. You can buy one from your local electronics supplier. It will cost no more than A$5 when the controller company would charge sometimes over A$100. Then if it needs callibrating add a variable pot of 10% in series or parallel to suit.
