    Default LG Window A/C Compressor does not turn off

    Model Number: lw1510er
    Brand: LG
    Age: 1-5 years

    Hi,

    I have a LG lw1510er and yesterday I turned the unit off and the compressor stayed on. I have checked the function on the display and I can change the fan speed, change the timer, modes and adjust the temperature but the temperature never physically changes it is always cold since the compressor stays on all the time. Nothing has been changed I cleaned the unit last summer and haven't has any trouble with it till yesterday. What could the problem be is there a relay that is failing or the board and are these parts serviceable? I have used this forum before and the help was right on and was able to fix my fridge with ease. I appreciate any help that is given.

    Hi,

    Yes it does sound like a relay for the compressor is stuck/welded closed all of the time = new board time...

    I should also state that when I turn it off and the compressor stays on, the only way for me to completely turn it off is either to unplug it or hit the test reset button on the cord to turn it off completely.
