There are fans in back of the unit that keep it cool. If one of them wont start it says that you need to check the fans. In order to do this you need to take the back off the unit and see how bad the dust is. YOu should get a vacuum cleaner hose and a brush and clean out the unit and then see if you can spot the fans. They are black and about 3 inches square. See if you can turn them by hand. You can then place the back on the unit and try it and see if the message goes away. If it does not then you need to figure what the interlock is that is on the back of the set that prevents it from starting with the back off. There is usually a tab that has to trip a switch. You need to defeat this and start the set while watching the fans. IF one of them wont start then that is your problem fan. You can take it out and replace it very easily. IF all the fans start then you have an issue with the fans sensor that detects if it is running and that could be a big problem .

Outside unit will only run for a short amount of time with A/C before the fan stops turning and starts humming, squealing/screeching and the top of the outside unit gets hot.

The bearings are bad in the motor and after the fan runs enough it eventually gets hot, making the bearing screech and the fan locks up. Need to replace motor again. See if it has a warranty. The reason it gets hot is because the fan is what removes the heat from the coil and if the fan isn't running there is nothing to cool it off so to speak.

I need to replace the cooling fan and heatsink on my Gateway ML6720. I'm having trouble finding the part. If I can find it, can you tell me how to replace it?

The best thing you can do is replace the fan itself with a like kind of shape and size. I usually do this by going to a computer store with the old fan and matching it up with the ones they have in stock, or measure the size in milimeters and buy one on line. The fan is held on by 4 screws and it is much easier than trying to remove the heat-sink and take the chance of damaging the motherboard. You can just screw the new fan to the old heat-sink and you are done, plug it in and insure the fan is blowing in the right direction and you are done. Good Luck, RAC
