Measure the resistance between the pins of the DB1 as below. If the resistance is ∞ or less than 1 kΩ, short circuit occurs on the main circuit.(R15001)YESYESNONOOutdoor fan system is functioning.Check the outdoor fan system.Go to Check No. 16.Outdoor fan running?Fan motorlead wire connectordisconnected?
