Fan in indoor unit: Start by using the remote to put the unit in fan mode. If the indoor fan starts operating this is the normal response.

If the fan does not operate at this time check these solutions:

A. Make sure the timer function on the remote is not on. If timer function is on use remote to deactivate.
B. Fan motor could be defective. Check for short windings or open windings. Must replace fan motor if these symptoms are found.
C. Fan capacitor needs a capacitor checker for this one.
D. Faulty control board, need to replace control board.
