do you have a new capacitor?
Are you using a cap with 3 sets of terminals on top...or 2 sets of terminals on top?
Customer: replied 1 year ago.
I have a new cap with 2 terminals on top 7.5 for new motor. Compressor will run off old cap
Customer: replied 1 year ago.
Old cap has 3 terminals
Expert:  BillyHvac replied 1 year ago.
thank you...the 2 browns go to new cap..one on each side...no other wires to cap except the 2 browns.
Then the yellow and black go straight to contactor..one on each side.
Follow so far?
Customer: replied 1 year ago.
So the yellow goes to the ground side on the power and the black goes to the black " hot power side?
Customer: replied 1 year ago.
Is that what you are calling the contractor?
Expert:  BillyHvac replied 1 year ago.
not ground..
at your contactor...there are 2 sides....2 hot legs come in one end...and then go out other end.
Are you familiar with the contactor?
Customer: replied 1 year ago.
No
Expert:  BillyHvac replied 1 year ago.
ok...do you see where main power comes into the ac unit from the house?
Customer: replied 1 year ago.
Yes and sorry, have to think 220v yes the 2 hots come to the bottom from house
Expert:  BillyHvac replied 1 year ago.
great...now those 2 hots end up connecting to relay/contactor...do you see that?
Customer: replied 1 year ago.
Yes then have terminals on top. That's where I connect the yellow and black?
Expert:  BillyHvac replied 1 year ago.
correct...you should see black wires mainly one side...and red or yellow on the other.
So black to one side and yellow to other...can you try this now?
Customer: replied 1 year ago.
