i have no blue wires going into any capacitors. There are 4 wires that go inside the coil. Two are blue, Two are red. One blue comes from the circuit board, the other from the heating assembly. The reds seem to form a loop. Following one from the coil, it leads to a capacitor where the other one comes out of and leads back into the coil. Other colors going to the heating assembly are green (which is indeed ground), yellow, orange (neutral line), white/black stripe, black, blue (on same screw terminal as electrical ground), and a grey, 2 element wire that is only to the temp sensor. the only wire listed above that does not connect to the heating assembly is the blue
