Hello, bogus error codes are common,

Please attach a close up photo of the wiring diagram glued to the inside of the blower access door and I will mark it up with trouble shooting instructions then follow up with step by step training and coaching until you have a solution.


Photo must be exceedingly well focused. Use the'add files 'link next to your send button to get the photo to me.
