Gargedoor closes and when immediately opens


That sounds like an adjustment issue. Say you leave something in the path of the garage door coming down. As soon as it hits it, it is going to immediately stop and move back up. With the garage door improperly adjusted, it is "thinking" it is hitting something when it touched the ground. There should be adjustment screws on the motor. Check your user manual to reference.

Chamberlain garage door will not close


If your garage door will not close from the open position and reverses immediately or part way down there is a safety beam problem, usually there is a safety light on the opener which will flash when the safety beam is activated or faulty. Clean the photo beams with a clean damp cloth, check if the door now operates, if it does not, check that the safety beams have not become misaligned, there is normally a light on one of the sensors that indicates when they are correctly aligned, if the light is on it means they are not aligned, the light off indicates they are aligned. If they are not aligned try adjusting them, if this does not work they are probably faulty.

Garage door closes and then opens immediately.


On the back of the motor unit you will find a control 'down force'. Turn this about 1/4 turn and try. This is for the reversing after moving a foot or so. Do not increase this control too much as it affects the safety.

If the door is hitting the floor and then reversing you will need to adjust the 'down limit' which is on the side of the motor unit. It takes a small screwdriver and you need to turn this control in the opposite direction of the arrow printed on the cover. Some tweaking will be necessary and remember if you run the motor too much a thermal switch will shut it off and you will have to wait 15 to 30 minutes for it to cool. This is normal so you will not be hurting anything.

Door will not close with remote.


The code you are seeing with 5 blinks is "RPM sensor or motor overload." We can eliminate the motor overload because the door is trying to close. The RPM sensor is a small printed circuit board just in front of the motor. It's a snap to replace and is available at any good door opener company. They will know exactly what you are talking about if you ask for an RPM sensor board.

Remotes don't work


I recently had Verizon FIOS equipment installed in my garage (for phone, internet and TV), which is plugged into a 110 volt electrical outlet. Thinking this equipment might be causing some RF interference, I unplugged the FIOS equipment, and both garage door openers immediately worked perfectly again!
After reconnecting the FIOS equipment, I then plugged the garage door opener into a different electrical outlet approximately 15 ft. away via an extension cord, and the openers continue to work fine. Fingers crossed, I hope the issue is permanently resolved.

Problem with craftsman garage door opener


There will be adjustment knobs on the side of the unit. Usually two white knobs that you have to turn with a small flathead screwdriver. These are the limit / load adjustments.

These adjustments are VERY sensitive, so be patient!
