Once identified, the technician consults the service manual’s decision tree for that specific code. For instance, if (Main contactor weld detection) is the top code, the manual directs: Step 1: Do not attempt to reset. Step 2: Manually check main contactor contacts for welding. Step 3: Measure coil resistance. Ignoring the top code and resetting the system could lead to a dangerous restart with welded contacts, a potential fire hazard.
