    What to do if my Trane RunTru 17 Air Conditioner unit doesn’t run?
    • G
      Gina Miller MDAug 3, 2025
      If your Trane Air Conditioner unit doesn’t start, it could be due to the overload protection switch delaying the start for three minutes; wait for three minutes before trying again. Alternatively, the unit might be in standby for one minute; allow one minute after turning on the power before it starts.

    Why does my Trane RunTru 17 Air Conditioner make sounds?
    • D
      David HarrisAug 8, 2025
      Your Trane Air Conditioner may produce sounds for several normal operational reasons: * It could be the electronic expansion valve initializing when the unit starts. * It may be the sound of gas refrigerant flowing during cooling. * The sound might occur when gas refrigerant starts or stops flowing. * It could be the drainage system operating. * The sound can also occur when the unit panels expand or contract due to temperature changes, both during and after operation.

    Why does mist come from my Trane RunTru 17 Air Conditioner?
    • B
      Benjamin GordonAug 11, 2025
      If you notice mist coming from your Trane Air Conditioner, it's likely due to indoor high humidity air being cooled rapidly. This is normal during the cooling cycle.

    Why does my Trane RunTru 17 indoor unit still run after I switch it off?
    • J
      Jennifer HughesAug 16, 2025
      It's normal for the indoor fan motor to keep running for 20-70 seconds after you switch off your Trane Air Conditioner. This is to use excess cooling and heating and prepare the unit for the next operation.

    Why does my Trane RunTru 17 Air Conditioner emit an odor?
    • S
      Stacey PerkinsAug 20, 2025
      If your Trane Air Conditioner emits an odor, it's likely due to the room odor that has been absorbed by the unit being blown out again. This is a normal occurrence when the unit is operating.

      olivia71Aug 25, 2025
      If your Trane Air Conditioner blows out dust, it's a normal occurrence after the unit has been off for a period of time. This happens because dust in the indoor unit is being blown out.

      elizabeth91Aug 28, 2025
