I have recently moved and our new to us house has four maestro fan/light switches. They all appear the same with model number MALFQ35 on the one I've taken out.
All three worked when I moved in a few months ago. Shortly the three upstairs sometimes work, and sometimes don't. The 14 little LED lights on the switch always work when the buttons are pressed, but the fan or light do not always turn on accordingly. Whenever the light does not work the fan also does not work.
Pulling the tab at the bottom always turns things off.
With the tab in the lights are generally stuck off, although one is occasionally stuck on. I have not yet seen any fan stuck on.
Tonight the one in my downstairs office refused to turn the light/fan on and the seven LED lights in the "light" (top) portion of the switch is stuck scrolling like it does when you first push in the tab at the bottom.
Is there anything common I should look for or have all four of these units in my house gone bad? I like their function and was considering adding more, but I'm not going to be in the position of replacing every switch in my house every 10 years, particularly at the cost of these.
