Hello, I need the brand of equipment, type (portable AC, or central system etc)...and model number.

Is there a sticker on the unit that gives you the narrative on what that code means? If so I need that too.

Meantime a brief note about error codes: They are very very useful about 30% of the time, the rest of the time they can be entirely bogus (bad printed circuit boards put out bogus error codes) or just not useful. With that in mind can you tell me what the system is doing or not doing and a lot about your technical skill sets so that I can coach you most effectively.

We can go from there.
