gotoman for ac :

On Samsuug units there is an extra wire that goes from outside unit to inside unit that switches the reversing valve. There is a white wire tucked behing the two boards on inside unit and one wire one outside unit. Russ

Customer:

all wires seem to be in order/connected ( there is the extra one on the outside unit like you said but there is no white wire tucked behind on the inside unit...

gotoman for ac :

Look in your install manual it connect to inside unit . On a Amcor it is a white wire. Russ

Customer:

this model doesn't have that wire..the older models do, though not this one. samsung have said they think it's the circuit board and that I have a DOA unit...sigh

gotoman for ac :
