Fan error problem

A Thermal error on the T43 usually indicates a problem with overheating. This can be caused by many reasons:
1. Dirt build up on fan or fan louvres causing fan to turn slowly and not being able to cool the system properly.
2. Blocking of air inlets to the laptop. Do not use on your lap, or on soft surfaces such as blankets, bedsheets, etc.

If you feel a lot of heat from the air out of the laptop, then the system is over heating.

You can run fan diagnostics as follows:
1. Turn on the computer and check the air turbulence at the louver near the PC Card slot.
2. Run Diagnostics --> ThinkPad Devices
--> Fan.

Here is the T43 maintenance manual to see how to check and or replace the fan.

The fan is not easy to replace...... The fan is located under the black transport belts. The fan is part
of the unit that brings the paper from the transfer & drum to the fuser unit. The unit is black and it looks like tank tracks. From what I remember the fan is acturely in the transport unit ... Good Luck

Have you had ur laptop for a while? If so it could be dust build-up, but when ever I came across a fan error it was usually due to the fan dieing out. Can you hear the fan at any point or is there no sound at all. If the fan is making no sound then you wont be getting much out of your laptop. Ive done more repairs for desktop fans and such, but laptop one might be a little more tricky to remove. Best thing to do if your not handy with this area is bring it to a computer repair shop. If the computer is new enough and still under warranty you should notify the warranty company of your problem.

You may have a faulty fan, check to fan, it should spin freely, if not the fan needs to be replaced. The fan and heatsink assenble may also be clogged with dust, remove the dust and vacuum to clean.

your cooling fan is reporting as damaged you need to replace the fan unit (cooling pad as well) likely service is required and unless you want to disassemble your laptop a service center would be better suited for this job.

The Service Manual says:

E02D05 Airflow fan error
Fan rotation could not be detected while the air flowfan as running.

Probable problem locations
Air flow fan, engine controller, system controller

Remedy
1. Cable connection check (check - replace
2. Replace air flow fan
3. Replace engine controller
4. Replace system controller


I wish success
