Sub-Zero reports faults in two formats depending on vintage: the older EC-prefixed service codes and the newer three-part numeric codes. Both narrow to the same handful of subsystems, so find the family rather than hunting the exact digits — and note the code before clearing it, because the variant sometimes decides which part we bring.
