This fault occurs when the VFD senses that 1 or more of the compressor wires are not connected to VFD. While this fault is active the system is inoperable. Check compressor wire harness at each end and ensure connections are tight fitting and wires are undamaged. Perform continuity test on compressor harness with DMM. Check resistance of compressor windings at VFD end of compressor harness to ensure no windings are open. Refer to Table 5 for compressor winding resistance by outdoor model.
