It's likely that the contacts are stuck closed. You can usually just tap them with a screw driver and they will open but then you should replace them. If you don't know where they are. Find the power wires coming inside the unit and follow them. Contacts are fairly easy to replace as long as you do it wire for wire. In other words when you remove a wire from the old attach it to the new before removing another. I hope this helps. Please don't forget to give me a Fixya rating.

You dont have a filter on top unit but you need to have your fan impeller and condensing coil clean regularly about once a year and more when your on dusty area.
