Opener keeps door open against the operator's hard-stop
This may happen for these reasons:
• There is a temporary soft failure – remove power to the controller and turn it back on
• If the problem persists, the controller may have forgotten some parameters – do a learn cycle
• If this happens as soon a power is applied to the controller, there is a hardware failure – replace the controller

• The controller is receiving a safety beam signal – see if the Beam LED is lit
• The delay is set very long and it hasn't yet expired
• A wire from the Program Switch is shorted to ground
• The trigger source is not working, or it's not wired properly – in that case the Trig LEDon the controller
