I'm new here and i've read a few post's on my problem but I'm a little confused as to how I wired the new cap and fan.
Yesturday when I came home from work the house was really hot which caught me by surprise. So I start diagnosing the problem and it was the fan that was not kicking on. So I gave it a push while the system was on and it started to turn fine. I figure well let me go a head and change the Fan motor and Cap. Problem is that the old cap and fan were different than the new ones I got. The old cap has 3 terminals One says 'FAN' that only has one tab connector, another says 'HERM' ,and the last says 'C'. The Fan has 3 wires 1 Brown going to the 'FAN' terminal One Black coming from fan to the relay, and a Yellow To the other side 'C' There is one light blue wire from the condenser to the 'HERM' side of the cap, also a yellow coming from the other side of th relay to the 'C' Terminal on cap. Ok now for how I wired the new cap and fan. First thing I noticed was the size difference of the cap it was half the size of the original cap and that it only had two terminals ( no labels on this one) The fan motor has four wires Brown, White/Brown, Black, White. The Brown and White/Brown were hooked up to the cap one on each terminal. So I put the black wire from the new fan to where the old black wire was on the relay, and hook up the light blue coming from condenser to one side of the cap and the yellow coming from relay to the other side of the cap. Now i'm left with this white wire. I turned on the AC and it worked without hooking up with the white wire exept for that after a while of it being turned off then it turning back on sometimes the condenser doesn't kick in. Fan kicks in just fine but condenser doesn't kick in at times. Can this white wire not being hooked up be the culprit of that problem? I read in another post that this white wire needs to go where the yellow wire from the relay is.
Sorry for the long post. BTW it's a Carrier brand unit.
Thanks In advance.
