Make sure your door sensors are properly pointed at one another and the small light on each one is lit and not flickering. If you just installed this opener you must install the door sensors.

You don't say but I am going to assume the door is stuck in the open position. Loosen the chain enough to relieve the tension on the trolley. Now run the opener until the door closes. While the door is closed locate the 'up limit' control on the side of the motor unit. Turn this control 2 full turns in the opposite direction of the arrow printed on the cover. Tighten the chain.

If the main light flashes 10 times and the door reverses to the open position it is a door sensor problem. Make sure the lights on the sensors are both on and not flickering. Tweak them if necessary. If you cannot get both lights to come on you have bad sensors or the wiring to them.

Usually when this happens it is because the door is open and the trolley is jammed against the bolt just in front of the motor unit. Try loosening the chain to relieve the pressure on the trolley and then close the door. While the door is closed locate the 'up limit' control on the side of the motor unit and turn this control 2 full turns in the opposite direction of the arrow printed on the cover. Now tighten the chain.

I have the same problem.The garage door opens or closes on its self after setting up the new remote chamberlain. i foun out every time my nabour closes his garage door mine opens.


Look at the LED light next to the SMART/LEARN button on rear of the motor unit. You may need to remove a light lens cover in order to see it. If the light is flashing rapidly this means you have a stuck button on one of your remote controls. Take the batteries out of each remote control. When you remove the batteries from the bad remote, the light will stop flashing. This remote needs to be replaced.


If one of your neighbors remote controls is inadvertently programmed into your receiver, you door will open when their remote is activated. If this happens you will need to clear out your receiver and reprogram your remote controls. Press and hold the smart/learn button for 6 seconds or until you see the small LED light near the button turn itself off. If the above steps have been followed and the symptoms continue, there may be an electronic short in either the wall control button or the receiver logic board. In this case, remove the wall control wires from terminals 1 and 2 on the motor unit. Should the symptoms persist after the wires are removed, replace the receiver logic board. If the symptoms stop with the wall control wires removed from the motor unit, replace the wall control button, and the wires leading to the wall control button.

Older model 1/3 hp craftsman goes up not down with remote


Your door sensors are either bad or need simply to be aligned. They must be pointed at one another to work properly. Each of them has a small light that will be lit when they are pointed correctly.

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.

Remote does not open garage door


It sounds like the wall button has the lock feature engauged.

Is there a small green LED flashing inside the wall button?
Push and hold the lock button for about two seconds and the LED should stop flashing. This will unlock the garage door opener and your remotes should start working. You may have to reprogram your remotes and homelink again since you triedprograming in the lock mode.

Good luck.

Hello bckp,
Welcome to Fixya


If your dishwasher does not run or stops during a cycle

Is the Start/Resume indicator flashing? Opening the door or
interrupting the power stopped the cycle. Close the door and
press START/RESUME.
Does the Start/Resume indicator flash 3 times when you
press START/RESUME? The dishwasher is waiting for you to
open the door after the last cycle. Open and close the door,
then press START/RESUME.
Is the door closed tightly and latched?
(NOTE: On models with a dual-digit display, the control
displays “- -” during a cycle if it believes the door is not
latched.)
Is the right cycle selected? Refer to the “Cycle Selection
Charts.”
Is there power to the dishwasher? Has a household fuse
blown, or has a circuit breaker tripped?
Has the motor stopped due to an overload? The motor
automatically resets itself within a few minutes. If it does not
restart, call for service.
Is the water shutoff valve (if installed) turned on?
It is normal for certain cycles to repeatedly pause for several
seconds during the main wash.

If the dishwasher will not fill

Check the overfill protection float that is able to move up and down
freely? Press down to release.

Let me know if any of these procedures helped you?

Huuum

Please remember to leave a rating.
