Hello, I'm replacing a fan and thermal unit on the Travelmate 6291-6753 The service manual says I only need to remove the thermal door to gain access to the fan and thermal unit
but I can't find a good diagram to locate if....anyon have any .jpgs of this assembly? where is the thermal door?
I'm sure can find it if I remove the chasis..but do I really need to take apart the entire unit to replace this part???
No, not necessarily the entire unit. Once you remove the chassis cover, the harddrive, optical drive & its fan, then you will see that the processor is covered with the heat sink or another term for it is thermal unit. You will not remove the entire motherboard of this laptop since the thermal unit is placed above the processor wherein the processor is placed at the center part of the motherboard. Another option is you can go to acer.com for manuals or you can call the acer tech support for more tech assistance
The dryer could think the door is open so it will not start the cycle when the start switch is pressed. You will need to remove the door switch to gain access to the wires on the switch. Remove one wire and tape it to the other wire. Try the dryer to see if it starts the unit. If it does turn the timer to off and order a replacement switch. If drum did not start to turn then you want to lift the top of the dryer to gain access to the start switch. Again remove one wire and touch it to the other wire to see if the drum starts to turn. If it did order a new start switch and replace it. The next item to check is the belt around the drum making sure it has tension on it. If not you will have to remove the front lower panel making sure the belt is around the motor pulley and tension rollers. Make sure the motor has voltage by using a volt meter. I do not have the schematics for this unit, and the last Item would be to check the thermal cut off and to trouble shoot the timer circuit.
