I took the condensing unit apart and follow the 24V blue wire inside the unit. As you can see on this picture:

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:

The other
24V is on T3. So I have no voltage on the electronic board. Can I skip the green and red parts inside the unit and connect the 24V wire directly to T1 on the board?
