My doors are set to auto close after 30 minutes of being open. Today I was working outside but was in the garage when the door started to auto close so I pushed the wall button to reverse it and leave it open. About 5 minutes later it started to close again again when I was walking in through the door. Even though I passed my foot though the door obstruction beam several times, the door did not reverse and kept going down until I grabbed the door to physically stop it from closing at which time it reverse and went up like it should. I confirmed that the door obstruction sensors were working correctly by pushing the wall button and passing my foot through the beam as the door was closing to make it reverse and go up. It appears that by interrupting the auto close by pushing the wall button, it somehow made the door opener ignore the signal from the obstruction sensor on the next auto close attempt which causes an unsafe condition. Is this normal?
