The Basic Troubleshooting Process
1. Prepare tools, information, and safety equipment.
2. Define the symptom.
• What is the problem?
• When does it occur?
• When did it work properly?
• When did it stop working properly?
• What was done in between those times?
3. Reproduce the symptom.
4. Narrow it down to the root cause.
• Proceed logically.
• Check the simple things first.
• Divide and conquer — rule out what is not the
problem. This is especially important to define if
the root cause is human error, electrical,
hydraulic, or mechanical.
• Believe your evidence — if all else is eliminated,
that which remains must be true.
• Never assume anything — check it yourself.
• Check everything — you could have multiple
faults.
5. Repair or replace the defective component.
6. Educate and train the operator when it is a case of
human error.
7. Verify the symptom is gone.
