calling Barry White or tilt-a-door experts!
One of our tilt-a-doors recently started to cause the securalift opener to misfire on opening and I can't seem to work out what is causing it. I've lubricated the closer chain with lithium grease which made it slightly better but it still trips up. Is there a checklist to run though to service these doors? It seems to be running freely enough when I disconnect it from the closer, and the weight feels about the same as the identical one beside it which functions normally:C
I'd offer a million thanks to anyone who can help out.
Cheers
Michael
