You replace a suspected faulty component, but the original fault persists unchanged. The correct next step is:
- AReplace additional parts until the problem is resolved
- BReinstall the original component and continue systematic diagnosis with measurements
- CDeclare the machine economically unrepairable
- DAdvise the customer to purchase an extended warranty
Correct Answer
Reinstall the original component and continue systematic diagnosis with measurements
Explanation
If replacing a component does not fix the fault, the original diagnosis was incorrect. Reinstall the original part (or keep the new one if it tests differently), and return to systematic measurement-based diagnosis.
