Hello my name is***** do not rate until we are finished. I look forward to assisting and am very sorry to hear that you are having this problem. Do you still need help with this? If you do, does the light flash in a pattern?
Does it respond to anything you try and do while this is happening?
The flashing is a fault code that is why I asked if it was in a pattern, a pattern would indicate what the fault is. Here is a tech manual:
Go to page 326 and please test the Eprom as it sounds like that is causing your issue. It is the control unit.
Not always, that is why I suggested testing it because what you have been describing sounds like a control unit failure. The board should have a number on it as well, and will be in the manual under that number. Let me know the number on the board.
Unfortunately I am unsure on this so I will opt out and open this to all experts.
