sticky buttons on ac unit
Hi everyone, now that the summer is on, and we use more of the buttons on our ac/ climate control unit, I have found out that the buttons have become stiff and sticky. They are hard to push/press, don't come back - or if they do that will be after a long delay, and the worst is that if you press them too hard the whole unit stops working. Any suggestions? Any help. And many thanks to those who helped me last time.
