    Why is my Samsung AW128AA Air Conditioner blowing air but not cooling?

      Lauren RossAug 7, 2025
      If your Samsung Air Conditioner is blowing air but not cooling, it could be due to a clogged or dirty air filter. Another reason might be that the desired temperature is set too high; try setting it lower than the current temperature. Also, ensure that the unit is not in "FAN" mode.

      If your Samsung Air Conditioner remote isn't working, first, check if the batteries are completely depleted or not properly inserted. Also, make sure that the receiving window of the remote for the assembly main PCB is not blinded. Another possible cause is jamming due to a nearby neon sign.

      Laurie LoganAug 27, 2025
      If your Samsung Air Conditioner is not operating, check for a power failure or if the power plug is pulled out. Also, check if the unit stopped because the sleep time has completed. If not, pull out the power plug for ten seconds and then reinsert it.
