AirConditioner Trouble - Review the Possibilities

clean the fan, or replace with a different fan. Fan usually don't cost much. I personally go to xoxide.com for all my fan needs.

Make sure that the fan is running properly & that the air ways are not blocked.
You can blow compressed air into the cooling vents of the fan. If you notice clouds of dust coming out, then it might be a good idea to disassemble the laptop, clean the fan & air ways, & reassemble it back. If the fan has failed & is no longer running, it might need to be replaced.

Hi fan was aorking fine then when u first turn fan on it made nosie .Now fan or light wont come on , i check power its fine

It appears your clutch or tub bearing has failed in this instance.

For replacement parts - head on over to PartSelect.com or RepairClinic.com and enter in your full model number for a full parts listing.
I recommend both sites because ...


FixYa has no affiliation with either site - I have been using and recommending them for years - trouble free.

PartSelect has a great schematic database for locating the part on your unit and great "testimonials" for each part that often times includes HOW-TO information.
RepairClinic has pictures of each part they sell and also a great how-to and troubleshooting for basic repairs.


If your unit has never been serviced - there should still be an original service manual enclosed in plastic taped to the inside of the shell.
In the service manual are Error codes, maintenance procedures, and troubleshooting steps you can follow.


Anything too complicated or beyond your scope should be handled by a professional.

If you think you want to tackle the repair - and have gotten stuck on a step - reply to your question and I will be glad to help you out.

one reason that a CPU fan may be running constantly is that it may not be able to cool the cpu down. usually this could be due to dust or debri clogging the incoming or outgoing vents or even dust accumulated on the fan itself or the heatsink.

Condenser fans (the fan next to the compressor) do run all of the time. That is normal.

I have no solution for this problem and I'm not sure I can fix it without taking it to a repair shop. The replies I got yesterday did not help.

yes. now you said the exact point.

if the fan keeps running and a sound comes and shuts the fan off.

this is the relay in the power board. and this relay trips down the supply.

check for the short circuits in power board and main board sir
