    Is there anything I can do to fix this?

    Is there a fuse in the LG AC unit?

  • tcduongxx Jun 23, 2009

    The plug have an over current on it and push it and it seem to reset properly. I plug it into the 120V and the indicator light on the plug shown to be on. The AC digital screen is not on and I push the on button it does not start. Can it something that is blown on the system circuit board?

Like most household appliances all does not use the 110 or 220 volt. The output from your socket is usually converted to DC. Electrical components such us the thermostat are running on DC at a lower voltage. LG released DC motors for Airconditioning, I am not sure with yours since I could not find the specs but surely your unit has internal components using DC.
To convert the power to a usable one, internally you should have a power supply inside. If you trace the power cord (while unplugged) it would lead to it. Some would have a fuse inside while others have none. If yours has one, just replace it or have it reset but if there are none you will have to replace it.

Hi,


If the fan does not operate, check the power supplu to the unit. Check to see if the breaker or fuse for the unit is tripped. If the breaker/fuse is tripped, check to make sure that it is the proper size circuit for the unit you have. On some units, there is a current interruptor on the power cord to the unit. Check to see if it is tripped by pushing the reset button. If the circuit is the proper size, then you can go ahead and reset the breaker/fuse. If it trips again, then you require further troubleshooting. Shut the power off and check all of the wiring in the unit to make sure that none of the connections is loose or damaged.
If the fan does not operate but the fuse/breaker is not tripped, you should check the run capactitos for the fan and compressor. If the capacitors are good but the fan motor does not operate, you can check the fan switch and the fan motor. Ensure that the fan blades spin freely.
If the fan motor operates but the compressor does not start, you should feel the compressor with your hand. If it is very hot, then you should allow it to cool. Then, you can take resistance measurements to make sure the compressor motor is good.
Then, you should attempt to start the unit in the cooling mode. As you do so, listen for a clicking sound which is an indication that it is attempting to start. If the compressor starts but does not cool properly, the unit may be low on refrigerant.
If the compressor attempts to start but shuts off very quickly, the compressor could be bad. Generally, if the compressor is bad on a window air conditioner, it is cheaper to replace the entire unit than to fix it.

Check and let me know if that would solve the issue.

Thanks for using "Fixya".

    or it could have simply just blown a fuse.
