    Hi folks,

    I'm having trouble with my window A/C unit and I'm wondering if you can help me diagnose the issue. It's an 8,000 BTU LG model# LW8016ERY7. For the past couple years, it used to work like a charm; now, it cools perfectly for about 2 hours but then suddenly gets caught, makes a humming/grinding noise, and stops blowing any air out. If I switch to fan mode the unit blows cold air for a few more minutes, then blows uncooled hot air from the outside. If I turn the unit off for a little while and turn it back on, the issue comes up right away, but if I give it a day to rest, it's ready to cool the room for a couple hours again.

    Any thoughts on the likely culprit?

    Many thanks,
    AJ

    sounds like it is going out on high head pressure. did you clean the condenser coil?
