How do I program my in-car transmitter to an Genie Intellicode or Chamberlain Security Plus system? You can find garage door limits on our Web site in the Genie section, or you can go directly to Genie limit switch.ģ. The ‘driven limits’ are located on the back or side of the motor head. If your chain drive has ‘driven limits,’ the limits are individually labelled and adjustable using a screw driver. If you have a chain drive with limit lugs attached to the chain, one for the up limit and one for the down limit, you need to experiment with the placement of the down limit lug on the chain, so the opener will shut off at the point the door closes. If you have a screw drive or chain glide unit you need to set the limit closer to the motor, so the opener shuts off earlier (at the point the door closes). In the down direction, if the limit is set beyond the point at which the door closes fully, the door will hit the floor and act as if it is hitting something and the safety feature tells it to reverse. These limits set the distance the door will open or close before stopping.
You have an open limit and a close limit on your garage door opener. The garage door closes down to the floor, hesitates and reverses back up to the open position. You can find new sensors on our Web site in the category section or by going directly to Infra-Red Sensors.Ģ. If nothing works, it may be that you have to replace the sensors. This acts as a reset and may reset the sensors. Also, try unplugging the garage door opener and re-plugging the unit back into the outlet. To try and correct the problem, make sure the eyes on the sensors are clean, the wire connections are securely fastened at the sensors and motor head, and the eyes are directed at each other. This method is the only way to override the safety and close the door. When this happens your garage door will only close by holding down on the wall button, or wall console, until the door fully closes.
You will find that the door will only move an inch or so in the close direction and reverse. The transmitters (remotes) will not work to close the garage door. The problem is either due to a blocked path between the sensors, dirty eyes, loose wires at the sensors or at the motor head, or just bad sensors. When the infra-red sensors are malfunctioning, usually one of the sensor lights will be blinking.
