Model # 350 Access Master 1/3 HP Jan. 06/ door opens fine but when we go to close it, it pops back open. we have checked around the sensors cleaned out all debris. You have to close it 3 to 5 time for it to stay closed. Any ideas would be great. We have lost the manual. Debbie dsalegriainc@comcast.net
