Module 6: Troubleshooting & Problem Solving

Understanding the Troubleshooting Process

Systematic Approach

When Something Goes Wrong:

1. STOP - Don't continue operating if malfunction occurs
2. OBSERVE - What exactly is happening?
3. DIAGNOSE - Use this module to identify cause
4. FIX - Resolve the issue
5. TEST - Verify problem solved
6. DOCUMENT - Record what happened and fix applied

Safety First:

• If electrical issue suspected: Unplug immediately
• If safety concern: Stop and contact supervisor
• If unsure: Don't guess - get help
• Never bypass safety features

Troubleshooting Quick Reference

Power & Operational Issues

No power at all

• • Cause: Not plugged in or breaker tripped.
  • Fix: Check the power supply and reset breakers. (See Power Issues)
