Hisense 12k window a/C. Rattling
What is the rattling noise? Sounds like coming from the compressor but don't know how to take it apart to see. It was brand new in box 10 minutes ago so it shouldn't be doing this.!!! It definitely isn't the fan because when you turn the unit off, the compressor stops first and the fan keeps going for approx 10 seconds and the rattling stops immediately when the compressor stops. Any idea how to fix this?
