I just noticed when I try to change air flow mode to window & feet, it makes grinding noise.... all other modes are smooth....

Does anyone else have this noise when switching mode for air flow ? Its not loud, but sounds kinda abnormal ( only when I switch it to feet & window, all other modes sound normal ).
You will have to turn off your fans to listen...

Is that normal?

 

As long as it only makes it when it is actually switching modes and not the entire time it is on that mode not too big of a deal...probably will just go away...mine did. If it is always on in that mode...it is abnormal.

 

Yeah, the noise is only present during actual swtiching, when the switching is done the noise is gone.. I hope its normal. The only reason I noticed is because all other modes make no noise, only switching to feet and window makes this noise...
Did you have the same issue?
