Replacing a fan and thermal unit

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???

The top freezer is working but lower part refrigerator compartment doesn't cool at all even adjusting temperature to Max cooling??? It is like fan doesn;t blow cold air from the freezer


Hello Eddie111,
If you were to remove the rear panel on the inside rear of the freezer you would then be able to gain access to the evaporator coil, If when you gained access to the evaporator coil you then noticed any ice build up on the coil itself this would be called a defrost issue that your unit was having. This is usually due to one of three parts either the defrost thermostat, the defrost heater, or the defrost timer or in some units the adaptive control board would be showing a fault. Would need you to message me back further if you do have a defrost issue with your unit. There is also a small damper door that lets the evaporator fan motor blow cold air into the refrigerator side of the unit this damper door is controled by a thermostat that is found in the ceiling of the unit. Usually attached to the control knob that is located inside the freezer. So first thing to check for is that the fan is working on the inside of the freezer next thing would be if you have the defrost issue on the evaporator coil itself, and lastly you would check the damper door and the thermostat inside the refrigerator side of the unit. If you have any further questions message me back with your reply to the defrost question that I asked previously. Thanks again I await your reply

Note: The edge of the thermal module is very sharp. So be careful when when removing it.

-------------------------------------------------------------------------------------------------------------------------------------------

Once the above steps are over, make sure to clean the thermal module and remove every dust found inside there.

after cleaning, make sure that the vents are not obstructed and then follow the above instructions in the reverse order to replace thermal module.

Hope this helps.

I am working with a canon imageclass d320. I believe there is a problem with the fuser and am wondering how i can gain access to the fuser? There is nothing in the manual about the fuser either.


Hello,
from the left side of machine there are door, when You open them you will have access to fusing unit, but only to the paper exit section.

To dismantle the machine you need to strip all the plastics and much more...

The oven keeps turning its self off


It could be the thermal cutouts operating. First things first, is the cooling fan running and does it turn off about 10 mins after the ovens/grill are turned off? If it isn't running then the unit is overheating and the thermal cutouts will operate. If it is running normally, then the cutout could be switching in early due to them becoming old and ineffective. There are two cutouts in the oven. One controls the main oven and the other controls the top oven. However, the grill operates without the clock being set, i.e. it is independent of the clock. So, if both the top oven and grill stop working together, according to the wiring diagrams in the handbook, the only thing it could be is the thermal cutout for the top unit.
F.Y.I. The top oven switch controls both the grill and the oven elements. In other words, in its OFF position, the Grill works and the Oven doesn't and in its ON setting the Oven works and the Grill doesn't. However, I can't see this failing as you specify, but worth checking if you take the oven to bits. The Grill will only work if the oven door is down.
If you need to replace the cooling fan, you will have to take the whole unit out of the kitchen cupboard to gain access to the top and rear oven panels, which have to be removed to gain access to the cooling fan and wiring. If you do replace it, ensure all the vents for air circulation are free from dirt and grease before you put it all back.
Try espares for STOVES spares. If the item is not listed you can ask them for a quote.
Be aware that the cooling fan is controlled by a timer circuit board and an in-line resistor on the fan terminal block. Either or both of these two and or the fan could have failed if the fan is not running! Any competent electrician should be able to work out what has failed.
All the diagrams are in the Handbook. If you need a copy, supply an email address and I will send you a pdf copy.
If you do ask for a quote, I suggest you ask for prices for all the parts mentioned above, so once you have checked what has failed, you will have enough info on pricing and availability as to whether to proceed or not.

My kenmore 500 series dryer will not turn on! it has power to the unit


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.

The oven and grill when in use switch themselves off after a while. They will switch themselves back on after a while.

I'm replacing a fan and thermal unit


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

Control panel access


Open the door and remove the top screws connected to the console. Close the door and flip the console down toward you. Remove the control cover to gain access to the control board and the thermal fuse.
