I took the condensing unit apart and follow the 24V blue wire inside
the unit. As you can see on this picture:
the blue 24V first goes into the "red thing" (don't know what it is)
and then it goes into the green thing. When it comes out, there is no
voltage on the wire. There is voltage (27V) when it comes out of the
red and changes from blue to yellow wire but no voltage coming out
from the green thing.
What is the red and green ? how can I replace it as it seems to be
permanently attached to the pipe?
The yellow wire that comes out of the green goes to T1 on the
electronic board: http://e-pixel.net/AC_condensing_unit.jpg
24V is on T3.
So I have no voltage on the electronic board. Can I skip the green
red parts inside the unit and connect the 24V wire directly to T1 on
