Before calling a tech check that the air filters are clean. Check that the condensate drainpipe is clear. You do this by blowing into the pipe which is on the outside of the building and should usually have water dripping from it. Then switch off power at the main supply board which should reset the unit. Then switch back on.

My Aircon indoor unit will not run continually on cooling. It runs for short bursts then stops.


One thing that I am not seeing in your description is that the coil sensor has been replaced. I find it strange that a phone tech could diagnose this, send out a technician and not replace this component. Was the service tech an authorized LG repairman? That is where I would start. I would call LG and ask them for a certified technician supported by LG in your area. I feel you will have better luck with that approach.

I have an AC unit with the model # PDH12K3SD-C the unit stops working and flashes an error cod = "06" anyone know what the error code means?


According to the Owner's Manual if the Error Code flashes "06" the O.D. coil Temperature > 175 Deg
F for 2 consecutive minutes. (Heat Pump models only).

The action taken by the unit is Alternate flash set point and error code. Shut unit down for 5 minutes, then try again 2 times, if fails the 3rd time, then shut down unit.:

All of this is can caused by several things:

• Dirty filters
• Dirty coil
• Fan motor failure
• Restricted air flow
• Improper refrigerant charge
• Restriction in refrigerant circuit

The dirty filters, dirty coil and restricted air flow you can troubleshoot and solve yourself. The reaming ones should be handled by a an authorized service technician.

Here's a link to your Owners Manual, that you can download and print for future reference.

Hope this helped to to troubleshoot and solve the problem . Please let me know. Thanks.

Air conditioner stopped working


Check the breaker in the panel and the fuses in the disconnect at the outside unit. If that doesn't do it. call a heating and air technician instead of an electrician.
