We have York heat pump HLKAO9FS-AAA Bought from was then Foodtown about 2006,  and the remote has stopped working.  tried new batteries will turn on & off but nothing else.
Any one know where I might find a replacement.  Tried using a Harmony remote to no avail.
The unit is not used much in our bedroom but wanted to use it on cool air not working.
Do I have to bite the bullet and replace as I think unit is about 15 years old!
