I live in arizona so may just be the heat- but everytime I close garage door with garage door opener/closer device from car- the garage door will close a half inch short and then pops back up--any ideas-could it be the sensors are off??? any help is appreciated thanks
If the opener works normally when operated by other openers and/or switches, then it probably means that your pushbutton on the transmitter in the car is sticking - or that transmitter is failing to stop "sending" in some other way.
If this problem occurs with all transmitters and switches, then I suggest you try adjusting the stops on the main unit.
