The unit isn't cooling, is leaking water, icing up, making unusual noises, shutting down, or showing an error code — but several different faults can cause the same symptom.
You know something is wrong, but you aren't sure whether to start with airflow, sensors, wiring, drainage, refrigerant, the control board, or the outdoor unit.
A small fault can turn into a long diagnostic process when you don't have a clear sequence showing what to inspect first.
Without a visual reference, it's easy to jump from one test to another, search through manuals, watch random videos, and still not know the next logical step.
Find the symptom you're seeing and quickly identify the most likely causes behind it.
See which components, connections, measurements, or operating conditions should be checked first.
Follow a visual diagnostic sequence that helps you move from symptom → cause → inspection → repair path.
Keep a practical reference available whenever you need to diagnose, review, or work on a mini-split system.
