[Decoder of the Code]

Thank you for your input. All filters have been cleaned and the coils also vacuumed etc. It does seem to be narrowed down to the 4th AC at this point only so maybe it just went out. I have worked the Tstat multiple ways and to no avail.

What is the best recommendation for this?
Just a new entire unit like a bic lighter?
If so which one for a 45 foot 2009 Newell?

Thanks again for the response for sure.
