The problem is with the infrared sensor cameras! You must check to see that both cameras have their led lights lit, if not you can position the one that does not have its light on which is called the receiver , The receiver receives a signal from the sending infrared camera and if it is not positioned correctly it will not receive a signal forcing you to hold down the wall station button . The reason for this is a built in security feature letting you know the sensors are not aimed at each other properly ,once you have an indicator light on both sides your opener should work fine and you wont have to stand their holding the button until the door closes ...Hope this helps you , good luck Glenn

How to get my garage door to open all the way?


Three blinking lights & door won't close by Candi
(Winston-Salem, NC)
Garage door will not open and close with remotes. Three blinking lights occur when we try to close door. What does this mean? It is a Linear unit.

I will assume you mean that your garage door will open with your remote but will not close. It should close if you press and hold the wall control button until the door is fully closed.

If that is the case, the 3 blinking lights indicate that your garage door's infrared safety beams are not properly aligned.

1) Check that the operator has power. The green lights on the sender and receiver should be lit.

2) If the receiver's green light is on, but the red light is off, the receiver has power but is not detecting the infrared beam from the sender. The red light might flash when the beam is partially detected. This can be caused by
mis-alignment or something blocking the beam.

Adjust the safety beam sender and receiver while watching the receiver's red light (stay out of the beam while aligning it). When the red light stays on, the beam is aligned and your garage door should operate normally.

NOTE: If the receiver's red light remains off, check for:

1) Dirt on the receiver's lens,

2) Sunlight shining into the receiver's lens,

3) A short in the safety beam wiring (from staples or at the operator terminals).

Why does my 973LM liftmaster remote will only open door bur wont close it?


Most garage door operators (openers) have infrared safety "beams". The door won't close, even with a wired push button, if something is in the way.

Back hatch wont open jeep cherokee 01


the switch in the back door will get seized with age. When this happens the latch assembly will stay stuck halfway open and closed allowing you to close the door. when the door locks the latch will jam. and now will not be able to open until the latch is freed up and unseized again. you will have to access the latch by going through the inside and popping the panel away from the door. then using a screw driver force the latch to the fully closed position. then unlock door and open. Lubricate the old latch till it moves freely. then it should work properly for you.. good luck

The interior lights wont turn off. they melted the old light bracket so i replaced it and the lights still wont go out


It sounds like you have a switch that isn't closing when the door shuts. I'm not overly familiar with the LG's, but looking at the Sears Parts Direct site, it looks like the door switches are in the hinge covers on top of the unit. There should be two of them, one for each door. But, only one has to not be working to keep the light on. The first thing I would check is to make sure the hinge cover isn't loose or out of position. The switch should close when the door closes. If the hinge cover moves, then the switch won't close. If everything is tight and aligned, then one of the switches is bad. That can be checked with a volt meter that does continuity checks. Unplug the unit before checking because those wires should be hot at all times. If you don't have a meter and want to do trial and error, just buy one switch since they both are the same. Here is the parts diagram showing the switch locations and part numbers:
http://www.searspartsdirect.com/partsdirect/part-model/LG-Parts/Refrigerator-Parts/Model-LFX25960ST/3204/0161000/K0810255/00001
The switch is 402A on the diagram, located on top of the box. If you click on the parts diagram, you can enlarge it to get a closer look.
The switch part number is 6600JB3007E
Hope this helps

VW Polo 2001 - Electric Windows wont open from Drivers side..


I removed all 3 switches from driver and passenger door, which is really easy with a flat head screw driver. took them completely apart, very carefully, with a small screwdriver out of a christmas cracker. put them back together again and 2 switches started working, so I put 1 in the drivers side and 1 in the passengers side so now my drivers door window opens and I lean over to open the passenger door. cool, no money spent...yet ;o)

your infrared sensor is either misaligned, faulty, or you have a broken wire from your sensor to your door opener. (Flashing light indicates infrared light path is broken). both sensors should indicate green led. door wil not come down is safty feature to prevent door from closing when light path is broken.
