Yeah my door is all working just twice now service light came on and had to power it down and up again then works fine. Could be a simple adjustment needed to stop it doing that. However b&d want $160 plus gst just to come to site. That gives me 30 mins. Then $40 per 15 mins after that. Probably to see all I have to do is adjust the limits or somthing lol hense my reluctance to call someone out.
