I had this issue. Some things work, some don't. Unless you know about the relays it is a real pain to figure out. When you manually actuate it, it might work for a few days but will probably stick again. What I found is it gets magnetized a bit. I ended up having to take the Q relay completely apart and giving it a good cleaning. When I put it back together all has been well since. There wasn't any dirt on it, but it was sticking to the coil plunger.
