No continuity between CN201 and S2 — Terminal block assembly fault

What does Electricity not conducted between CN201 and S2 mean?

There is no electrical conduction (0 Ω resistance) between the connector CN201 on the indoor power P.C. board and S2 on the terminal block. This indicates a break in the wiring path.

• Faulty terminal block assembly
• Internal wiring break between CN201 and S2
• Poor connection at the terminal block
