Garage Door Reverses After Fully Closing

Safety Sensor Eyes for Liftmaster,Chamberlain & Sears Craftsman Garage Doors

All craftsman garage door openers are equipped with a reversing feature. This is a safety feature that prevents accidents and also protects the opener from damaging. When the garage door opener is first installed, it is programmed to learn the fully open and fully closed position, and then it stores it to memory.

When the garage door is closing, and it doesnt reach the fully closed position, it assumes there is an obstruction in the way, and then it reverses. This helps protect objects which may not have been detected by the safety sensors.

Here are the troubleshooting steps to follow when your Craftsman garage door opener reverses after fully closing

Check The Safety Sensors Connection To The Garage Door Opener

If the Diagnostic LED on your Craftsman garage door opener blinked two times, then it means the safety sensor is disconnected from the garage door opener. To troubleshoot this, first, check if any of the safety sensor wires have been disconnected behind your Craftsman opener. Also, verify that the wires are properly connected to the safety sensors as well.

Also, inspect the sensor cable for any signs of damage. A damaged cable may be the reason why there is short-circuit. If the cable is damaged, then you need to have it replaced.

Why Is The Green Sensor Flashing Or Flickering

If one of the sensors flickers, theres a poor signal reception on this receiver sensor. There are typically three reasons for that.

  • Dirty lens on one or both sensors.
  • Sensors are not perfectly aligned.
  • Wiring issue with a poor connection.

First, clean both sensors. Then have a quick look and see if one of them is not facing sideways. It is easy to accidentally bump into one of them and get them out of alignment. If all looks fine, grab the receiver sensor and twist it gently towards the garage door while looking at the LED indicator. If the light changed from flickering to solid theres a good chance you just fixed your issue. If that didnt help and the light still isnt turning solid, inspect the wires and look for damage or poor connections. Finally, if nothing helps, this is the time to pick up the phone and call your local garage door repair company. They will be able to troubleshoot, repair or replace your garage door sensors if needed.

    How To Bypass Garage Door Sensors

    First of all, you will only be able to bypass your sensors from the wall button. Sorry, this is not a permanent hack of the opener. It will however, work on any garage door opener no matter the brand. It is not a good idea to have sensors that do not function properly. The opener may not be smart enough to know that there is nothing really in the way so we have to convince it we know better. So, all you need to do is hold the wall button down . You must hold the wall button all the way down until the garage door hits the floor then release. If you let go of the button before the door hits the ground the sensors will kick back in to action and the door will reverse. This will allow you to close the door and have it locked into the down position using the opener. Now at least you do not have to leave the door up all day or night.

    Garage Door Opener Craftsman Closing Problem Sensors

    I’ve got a 6-year old Craftsman opener that works great in most every way but when it needs to close. Currently I have to hold the operator button down during the full close cycle. It is due in some manner to the fact that there seems to be something wrong from the door sensors, although they are aligned well and have never been bumped, knocked out of align, etc.

    The issue originated as a come and go occasional problem but has upgraded to a full time problem.

    During the problem time periods, the light on the sensors is either dim, very dim, or non-existent.

    The only other condition with the opener – although I don’t know if this is related to the main closing problem but it appears it could be – is that over the time I’ve had the opener, I’ve had to increase the down force adjustment knob several times to where it stands currently. And currently it is set to the limit of it’s adjustment range where the highest force to the door is being applied to close it.

    Anybody have any ideas as to what is wrong or bad, and can it be fixed or is this something that requires an entirely new opener. Thanks for any insight or experience you may have that could help me on this matter. Any thoughts are much appreciated.

    Wall Control Not Working

    When your Craftsman openers wall control is having a problem, the Diagnostic LED will blink three times. Also, the LED on the wall control will be off. On the newer models, the UP arrow button flashes once, and the down arrow flashes three times. This means there is a short-circuit in the wall control wire connection, or the wall control is faulty.

    To troubleshoot this issue.

  • Remove the wall control from the wall, and disconnect the wires from the back. You will need a screwdriver for this
  • Touch the bare ends of the wire together to see if the garage door activates. If the garage door opener works, it means the wires are in good condition, but the wall control is faulty, and you need to replace it with a new one. If the opener does not work, perform the next steps
  • Disconnect the wall control wire from your Craftsman opener.
  • Cut a 3-inch strand of insulated wire and peel the ends. You will use it as a jumper wire in the next step
  • Insert the jumper wire into the wall control terminals on the garage door opener to see if the garage door moves. If the garage door opener works with the jumper wire, then there is a break in the wall control wiring, and you have to replace it.
  • If your wiring was damaged, you need to have it replaced, and this Universal Garage Door Wire is an excellent wire for the job. Its about 90ft long, which is more than enough for the entire wiring without having to join wires. It simply gets the job done.

    All garage door sensors produced by Chamberlain Group will work for all openers manufactured by the daughter companies.

    Liftmaster, Chamberlain, Raynor, and Craftsman garage door openers will all work with a set of standard Chamberlain sensors.

Therefore, hiring a professional garage door company is essential if you need your sensors replaced. Otherwise, do proper research before buying a set of sensors for your garage door opener unit to avoid returns and loss of time.

    Over time, weather, dampness, and corrosion change the condition of the tracks and rollers, which also affects the opening and closing cycles of your Craftsman garage door opener just as it would affect a Chamberlain opener. You need to increase or decrease the openers force to compensate for these changes on the tracks and rollers. The force setting is the power that controls the drop and rise of the garage door.
