I would say your 9 year old opener that is not lighting up is bad.

Sears garage door opener 1/2 hp about 6 years old. Will not respond to remotes to open and close. Light flashes on opener when remote is pressed but no door action.


Door sensors are not working. Check if lights are on both sides.
Might be misaligned or one is bad.
Door will close if you hold in the garge close button until it's all the way down.
And it will open on it's own.
You can get these off ebay.

My 20 year old liftmaster model 1040 or 1050 opens on its own. I changed the remote code 3 times and replaced the wall switch. Any ideas? I even went around the neighborhood to see if my remote worked on...


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

If one of your neighbors remotecontrols is inadvertently programmed into your receiver, you doorwill open when their remote is activated. If this happens you willneed to clear out your receiver and reprogram your remote controls.Press and hold the smart/learn button for 6 seconds or until you seethe small LED light near the button turn itself off. If the abovesteps have been followed and the symptoms continue, there may be anelectronic short in either the wall control button or the receiverlogic board. In this case, remove the wall control wires fromterminals 1 and 2 on the motor unit. Should the symptoms persistafter the wires are removed, replace the receiver logic board. If thesymptoms stop with the wall control wires removed from the motorunit, replace the wall control button, and the wires leading to thewall control button.

Program garage door opener in 2005 rx 330


There are 3 programmable Homelink buttons you can use for different remotes. Just to the right of the buttons there is an indicator light.

Decide which button you want to program. Point the none battery end of your remote 1"-3" away from the Homelink panel and press both the remote and desired Homelink button down and hold them down at the same time. After about 20 seconds, the Homelink indicator light will change from a slow flashing to a rapid flashing. You can then release both buttons,
If the garage door responds to the Homelink, your done! If not, your garage door uses a rolling codes transmitter and must be trained.
Find the training button on your garage door opener's transmitter (usually mounted on the ceiling). Press the training button and within 30 seconds press and release the programmed Homelink button twice. If the garage door opener operates, you're done! If not, press and release the Homelink button a third time and the garage door should respond. If it still does not, you may have a very old garage door opener with a none digital transmitter (like I did). In that case, you either need to buy a new opener or try to replace the transmitter with a modern digital unit (as I did). Advantage: cheaper than a whole new garage door opener.
Disadvantage: The newer openers incorporate safety features that my old opener does not have.

The keypad is not working. I forgot how to set the code.


I just had a similar problem, and when I opened the button/panel on the inside of the garage, I realized there is a 9-volt battery there. That battery was more than 5 years old - no wonder it died.
One extra symptom, when the code was not working, I got no LED lights on the panel -- with a fresh battery, I now get an LED working. If you're not getting any light, check for a battery.
