Two brand news ac unit out of box will not work

Here's some things that could be causing your issue.
A clogged air filter could be one possible cause.
However I suspect the units high limit switch is the culprit.

Hi,
1-Check Thermostate for setting may wrong or Th. faulty.
2-Fuse near to heating element blown, Change it.

First of all you need to check if your power supply to unit is correct (120v or 220v).

Reverse the wires in the receptacle ,not the ground,this is most likely the problem the way the circuit is set up in the ac unit.Let me know if this helps.

Actually you should buy and install an AC wall outlet. An AC uses more amperage than most any other appliance due to the fact it has 2 motors the compressor and the blower / fan motor. An AC wall plug has larger terminals so that the plug does not ever heat. Changing the cord to a different and smaller terminal plug is a bad choice due to the danger of overheating the wall outlet terminals. You can buy the AC horizontal terminal outlets at any hardware store. Unless you have a 110V AC unit you will also have to run a 220V #10 Romex (3 wire) with ground to the outlet to be in code.. An AC unit 1 HP (10,000) BTU or larger requires over 15 Amps for start up. Those that are 20,000 BTU or larger obviously require more than 15 amps as a power source.

Thanks for using FixYa.

I just bought the LG 10000 btu window model... I am having the same exact problem.. it feels like the air is not even on.. I am having someone look at it on Mon. I have a feeling the whole unit is defective. But it could be the thermostat needs to be replaced. Sucks 300 dollar brand new AC and it doesnt work!! Good luck. I will never buy LG again.

The heat fan speed is slower than the cooling speed. About 300 rpm less.
You may not have a problem.
