How to Fix / Troubleshooting
Safety: Disconnect power before accessing the fan assembly.
- 1. Reset and listen: After reset, listen for the fan starting. If it hums, squeals, or does not start, there is likely a fan issue.
- 2. Visual inspection: Remove the front cover. Check the fan for dust buildup, foreign objects, or signs of overheating.
- 3. Spin test: With power off, gently spin the fan impeller by hand. It should rotate freely without grinding.
- 4. Check fan connector: Ensure the multi-pin connector from the fan to the PCB is secure and free of corrosion.
- 5. Technician tests: A professional can measure supply voltage to the fan and verify tachometer feedback to the PCB. Replace the fan assembly if it does not meet specifications.
