Air conditioner fan not starting

[QUOTE="russ_watters, post: 6139221, member: 142"] Yes. Do you have a wiring diagram for the indoor unit's controller? Can you verify the signal is being sent to the brown wire at the unit? Can you verify the continuity of the brown wire? This issue may be as simple as a bad control wire or it may be a lot more complicated. The fan may not always run, but might be controlled based on refrigerant pressure, and you may have a bad controller or sensor. [/QUOTE]
