Mine is exactly the same. I've stripped it down and there is a small water pump that has burnt out. I think what happens is that everything inside gets covered in thick fluff. This can then get damp and it causes arcing across the electrical contacts and corrosion.
Check out the price from Gias and Partmaster.
You need to be electrically competent to replace this part. PS Does your condenser assembly keep fluffing up?
