Sounds like one of your door springs has broken or the drive gear is going bad. The gear is white nylon and is just in front of the motor.

How do i get to the door ajar alarm in my 2002 kia sportage? Want to yank the alarm out.. Is it under the radio? Want to get an idea before i take the dash off again


there could be a bad or not totally depressed door switch/es when all doors are closed, assuming the alarm system module (not sure of the name, some manufacturers call it body control module-'BCM') is good. you may try the following:
1. if there is, tighten each lock nut (or mounting nut) of the door switches, to bring out each door switch so that they will be fully depressed when the doors are closed.
2. to find out which switch/es is not being fully depressed when door is closed: while (& all doors closed) door ajar alarm is on, open one door & manually depress the door switch (try to depress several times - might be sticking). if alarm turns off you found the switch, otherwise continue to the next door. but before proceeding to the next door, tape down that first door switch (you may have more than one?) once you found the switch that is not being fully depressed when door is closed, tape down that switch (to keep the alarm turned off). go back to each taped down switch. remove tape & close door, if the alarm turned off when the door was closed (switch is fully depressed=good), then go to next.
3. you can skip 2, just install spacer to doors. spacer can be a thin piece of plastic (or something weatherproof cardboard) to make the door switches to fully be depressed when doors are closed., not too thick that may prevent door from properly latching). tape them first, then use good adhesive if they work.
other possible causes are bad door switch, broken or detached wire, or bad BCM)
(note: the door switch is a push button which looks like a small protruding nail? & mounted at the door opening, which will be depressed by the door upon closing).

How do you stop the door leaving a foot open at the bottom?


To stop the door in a partially open position, the button on the wall switch or remote should be pulsed when the door is opening from the fully closed position.

My liftmaster will not close the garage door


Photo cells "safety beams" not aligned or bad, holding wall control will allow you to over ride them.

The garage Remote control was working normally at first then for now reason now it just opens the garage door but doesn't close it. I checked the side sensors they look OK & clear, and I...


It could be the garage door motor that is acting up. Try closing it with the button in the garage. If that's not the case, you may need a different garage door opener.

The motor runs but it only opens a few inches and slowly goes back down its a chamberlain whisper drive model HD900D


Hi. I have seen this before, although usually not from chamberlain garage door openers.

Pull the release cord that unlocks the door from the opener, and manually open the door ALL the way open.

Then lock back in place in the open position.

Then use automatic opener to shut door.

It will close very slowly, but should close all the way.

Then, open the door again using the remote, and the door will once again open slowly, this time it should open all the way.

Then close door with remote, and door should now close as it is supposed, with the proper speed.

The slow opening and shutting is the system position sensor resetting itself.

This is why your door is acting up.

I would also look up by the belt drive connects to the front of the garage door opening, to make sure there isn't any dirt, cobwebs, or other obstructions on the sensor that may cause it to re-close the way it does.

My Liftmaster 1/2 H.P. opens but cannot be closed (without depressing the button on the wall until the garage door comes down all the way. Any help will be much appreciated


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?

How do you set the garage door opener for a 2004 toyota 4runner LTD?


You hold the remote close to the three buttons on the vehicle. You choose which button you want the remote to transmit to, and you hold it down. With your other hand, depress the garage door remote opener, and hold it very close to the 3-button assembly. Wait for the red L.E.D. light to blink slowly. If it does not blink slow, continue moving the remote around, until it does blink slow. When it starts to blink slowly, stop moving the remote around. Wait until the light starts blinking rapidly. When the light blinks rapidly, the process is complete.
