What are the possible reasons for sound coming from my Trane 4MXW3812A1?
Several sounds can come from your Trane Air Conditioner: the electronic expansion valve initializing, gas refrigerant flowing, gas refrigerant starting or stopping, the drainage system operating, or the unit panels expanding or contracting due to temperature change.
Why does my Trane 4MXW3812A1 Air Conditioner blow out dust?
The dust blown out from your Trane Air Conditioner is caused by dust in the indoor unit being blown out.
Why does my Trane 4MXW3812A1 emit an odor?
The odor emitted from your Trane Air Conditioner is caused by the room odor absorbed by the unit being blown out again.
Why does my Trane Air Conditioner show a mode conflict?
When the indoor operating mode conflicts with that of the outdoor unit, the indoor fault indicator will flash and conflict will be shown on the wired controller after 5 minutes. The indoor unit stops running and the outdoor unit changes its mode of operation to match the indoor unit, then the unit will go back to normal.
Why does mist come from my Trane Air Conditioner?
The mist coming from your Trane Air Conditioner is caused by indoor high humidity air being cooled rapidly.
Why does the indoor unit of my Trane 4MXW3812A1 Air Conditioner still run after I switch it off?
The indoor fan motor in your Trane Air Conditioner will keep running for 20-70 seconds after you switch it off. This is to use excess cooling and heating and prepare for the next operation.
