    thanks for the suggestion mjrock, but i understand the garage door system and how it works. there is no obstruction in the safety sensors path and the lights on each sensor are working. i feel, however, that my problem has something to do with the safety sensors since the area i live in was hit by hurricane IKE and my garage received flooding which covered my safety sensors. do you think i should replace them or should i look elsewhere for the source of my problem? i have checked the up & down ajustment limits & they are working fine.

Hello,

There should be 2 sensors on the bottom of your door on the inside, 1 on the right side and 1 on the left side.
These sensors serve 1 purpose to send a beam or reflection to each other.
If something is blocking this reflection or is in front of the sensor the door will always come back up.
It is a safety feature so nothing or no one gets hurt when the door is closing!

Is there a battery in the Craftsman 315 MHz Garage Door Opener Premium Control Console?


The Premium Control Console on the inside wall of the garage is hard-wired to the garage door opener. When I've needed to press and hold the button on the unit, there's usually something wrong with the opener or the garage door hardware.

The problem could be with the travel or force adjustments. However, more likely, the door is binding during travel or the garage door opener gears are damaged. Disconnect the door from the opener and check how it opens and closes. Is the door binding anywhere? Check if the rails are bent or if the framing of the door has rotted at the bottom. (We had one garage door where the door jamb was damaged. This led to the doorway shrinking and the door jamming.) If you open the door part-way, does it stay at that position? Do this test carefully; you may get injured if the door falls. If it doesn't stay open, then the torsion spring tension may need off or the springs need to be replaced. If the springs are mounted next to the doorway, you need a professional to check the springs. (If the torsion springs are further from the door, you may want a professional to check them. You will need to use vise grips or a similar tool to keep the door partway up and prevent it from falling when you adjust the tension. You will need to adjust both sides evenly.)

When you press and release the garage door opener button, how far does the door travel? Do the opener lights blink three times? Are both obstruction sensor (often green and amber) lights lit? Please add a comment with more information about the symptoms for additional help.

I hope this helps.

Cindy Wells
(note: when there is a problem with the door binding or the torsion springs failing, it's not uncommon to see the garage door opener fail. The motor tried to force the door and the plastic gears end up stripped. You may need to replace or repair the opener after fixing the door hardware issue.)

How to open the door if no electricity


Almost all garage door openers have a switch mechanism that will allow you to open the door manually. It is usually a pull cord on the motor or track. Pulling it down usually deactivates automatic mode. Just pull it up into position when the electricity comes back on.

Door goes down and when it stops at botton, it turns and goes back up ??? Need adjusting ..How can I adjust???


Adjust the position of the door by using the black and purple buttons. Black moves the door UP (open) and purple moves the door DOWN (close)
Setting the up position: 1. Press and hold the black button until the LED starts flashing slowly, then release. 2. Push and hold the black button until the door reaches the desired UP (open) position 3. Push the door control or programmed remote control. This sets the Up (open) position and begins closing the door. 4. Immediately when the door begins to close press and release the black or purple button. This will stop the door Setting the Down position: 5. Push and hold the purple button until the door reaches the desired DOWN (Closed) position. 6. Once the door is closed, If there appears to be too much pressure on the door, you may toggle the door back and forth using the black and purple buttons to reach the desired closed position. 7. Push the door control or programmed remote control. This sets the Down (closed) limit and the door should open.

When I try to close my garage door --4100 model-- the door travels part way down, then reverses and goes to the up position. I can force it closed by keeping the garage door wall switch continually...


Check your door sensors. Make sure they are pointed at one another and the small light on each one is lit and not flickering. Tweak them a little. If you cannot get both lights to come on you have a bad sensor.

Wall mount button LED is flashing, remotes won't work, door won't close unless the wall mount button is held down until the door is fully closed


Sounds like you have a couple problems. First of all press and hold the button on the wall control that has a lock icon for 3 seconds and release. This should take care of the flashing LED and the remotes will now work. Having to hold the button on the wall control until the door is closed is usually a problem with the door sensors. Make sure they are pointed at one another and the small light on each is lit and not flickering.

Garage door opener will not continue to open garage door.


You say your door won't open and then you say your door won't close. Anyway you have a door sensor problem. Make sure they are pointed at one another and the small light on each one is lit and not flickering. If you tweak them and the lights don't come on then you have either a wiring problem or a bad logic board.

Liftmaster pro 1/2 hp wont shut in one button press


You have a door sensor problem. Either your main light bulb is burned out or you don't have one in your opener. The clicking sound you hear is the relay for the light. Both of the door sensors should have a small light that is lit. Tweak them until they are.

Garage door


TRY THE DOOR MANUALLY AND RUN THE OPENER DISCONNECTED FROM THE DOOR(WITH DOOR IN CLOSED POSITION).

THIS SHOULD ISOLATE THE PROBLEM (ACTUAL DOOR PROBLEM OR OPERATOR PROBLEM).

HOLDING DOWN THE WALL BUTTON OVERRIDES THE SAFETY EYES.
WHEN HOLDING IT DOWN MAKES THE DOOR CLOSE PROPERLY THE PROBLEM IS IN THE SAFETY EYES.

ARE BOTH LEDS ON? - CHECK FOR A LOOSE OR BROKEN WIRE.
ARE THE EYES WIRED CORRECTLY?
ARE THEY AIMED AT EACH OTHER?

IF THE DOOR STOPS/REVERSES (WITH DOOR CONNECTED) WHILE HOLDING DOWN THE WALL BUTTON TO CLOSE YOU NEED TO CHECK THE SENSITIVITY ADJUSTMENT.

HOPE THIS HELPS

Liftmaster garage door opens and shuts but when it reaches the closed position on the floor of the garage, it automatically reverses and opens back up again.


is there something jamming it travel of the door?
or does the travel distance of the door need adjusting?
How many remotes do you have?
do their batteries need a changing?
even with the power disconnected you should be able to close the door,
do this and check from there,
any of the switchs sticking down?

If it persists then call some one to fix it,
They are normally bullettproof if installed properly and servicing and lubracating them seems to be a good idea too,
some buildings shrink and contract more than others
Yours seem to be normal movement of the building structure.
winter and summer situtation.

check the adjustments on the travel,

Let me know the outcome thanks .....
