Thinking Process:

1. Deconstruct the Prompt:

   • Goal: Write a short, genuinely useful companion article for a developer/DIY community blog.
   • Source: Bosch Refrigerator E02 (evaporator fan motor failure).
   • Constraints: 350-450 words, original content, practical advice, clear hook, 2-3 subheadings (##), reference source once with specific link, end with a takeaway, plain language, no SEO/backlink mentions, output only markdown, start with # Title.

2. Brainstorming Angle & Value Add:

   • The source covers E02, causes, costs, quick fix.
   • What's missing or what adds value for a DIYer?
     • Pre-diagnosis: Sometimes E02 is a false positive. Wiring issues? Ice buildup blocking the fan? Control board glitch?
     • Safety: Compressor heat, electrical safety.
     • Tools: What specific tools does a DIYer need?
     • Troubleshooting flow: Don't just buy a motor; check the easiest things first.
     • Angle: "Before you buy a new motor, check these three things." This is highly practical for DIYers who hate wasting money on parts that aren't the root cause.

3. Drafting - Section by Section:

   • Title: Needs to be catchy but useful. # Bosch E02 Error: Don't Replace the Fan Yet. Or # Troubleshooting Bosch E02: Check These First. Let's go with # Bosch E02 Error: Skip the Part Swap Until You Check This.
   • Hook: No "In today's world." Start with the problem. "Your Bosch fridge just threw an E02, and your first instinct is to order a new evaporator fan motor. Hold that credit card."
   • Body/Subheading 1: ## The "False Positive" Trap.
     • Content: E02 means the board doesn't see the fan spinning. But the fan might be fine. Ice? Wire harness?
     • Advice: Check for ice. If the evaporator is iced over, the fan blade is physically blocked. The board throws E02, but the fix is a defrost cycle, not a new motor.
     • Actionable: Unplug, remove back panel, look for frost on the coils/fan.
   • Body/Subheading 2: ## Multi-meter Magic: Voltage vs. Resistance.
     • Content: If no ice, check the motor. But do it right.
     • Advice: Check resistance first. Then check voltage at the connector while running.
     • Actionable: Set meter to Ohms. Probe the motor terminals. If infinite, motor is dead. If resistance is good, check if power is reaching the connector.
     • Source Link Insertion: "For a deep dive into the wiring diagram and part numbers, check out the complete guide."
   • Body/Subheading 3: ## Reset Before Replace.
     • Content: Control boards glitch.
     • Advice: Hard reset. Sometimes the board latches onto an error.
     • Actionable: Unplug for 5 minutes. Listen for the "click" of the board resetting. Plug back in.

       Bosch E02 Error: Skip the Part Swap Until You Check This

       Your Bosch fridge just threw an E02, and your first instinct is to order a new evaporator fan motor. Hold that credit card. While E02 flags a fan motor issue, replacing the part immediately is the most common way DIYers waste cash. The board is simply reporting it can't detect the fan spinning, but the root cause isn't always a burned-out motor.

       The "False Positive" Trap

       Before you yank the motor, look at the evaporator
