A couple things you need to check right off. First is the door springs. They are usually above the door and if one of them breaks they will cause this. Check closely they sometimes look okay. The next thing is to remove the cover and check the drive gear of the opener. Usually this is obvious when it goes bad because you will find what looks like white sawdust on the inside of the cover. If both of these are okay you can increase the 'up force'. This is normally on the back of the motor unit near all those white wires depending on the manufacturer.

GT3-R -can


This is a dual frequency transmitter. (315/390) You need to select one button to program the TYPE 1 frequency of 390 MHz. Here's how:

Backwards compatable programming instructions for GT3-R dual-band remote: This is a 3 button remote, which can be used to operate up to 3 garage doors using IntelliCode radio controls. This remote is defaulted to operate the new IntelliCode 2 Genie garage door openers, but you can also program individual buttons to operate other IntelliCode 1 (pre 2011) models of Genie garage door openers made from 1998 to present. To change a button to operate a pre 2011 IntelliCode opener, the default IntelliCode 2 setting must be changed to IntelliCode 1. An LED light on the remote displays which mode the remote button is in: Red = IntelliCode 1 / Green = IntelliCode 2 To set one of the 3 buttons to be IntelliCode 1 (red), follow the instructions below:
  1. Select a button on the remote that has not been programmed.
  2. Press and hold that button for 10 seconds. Both Red and Green LEDs come on and stay on.
  3. Press the same button twice to toggle IntelliCode selection from IntelliCode 2 to IntelliCode 1.
  4. Press the same button again to confirm toggle. the LED should be Red. The IntelliCode selection for this button is set to IntelliCode 1.
You are now ready to program the remote to your garage door. Follow accompanying instructions for "Programming to IntelliCode 1 Genie garage door opener," or see below instructions: Programming Instructions: Gently press the Receiver Learn Code button on the power head receiver of your Genie garage door opener (motor head on ceiling in garage). This small, black, unmarked button is located behind the light lens at the motor head and is nearest the floppy 6 inch antenna wire that protrudes from the motor head. When pressed, a radio signal indicator light will start blinking red for 30 seconds. After pressing the Learn Code Button, press your transmitter button twice for your system to grab the frequency and code it in. (Keep the transmitter you're tuning at least 2 feet away from the power head while tuning.) Press the transmitter button once more to test the system and start your door moving.

Craftsman Garage Opener (Unit run front & back only for 2 second)


Double check to make sure the sensors are wired correctly. The 2 solid white wires go to terminal 2 and the wires with black stripes go to terminal 3. If the wiring is correct then you possibly have a bad RPM sensor. The RPM sensor is a small circuit board just in front of the motor.

Having trouble setting garage door opener to my 2004 trailblazer


1. Position vehicle within 10 feet of garage door- engine off and battery on.

2. Press/hold 2 outside buttons of Homelink transceiver until red indicator starts flashing rapidly, then release button. This should take about 20 seconds. This erases any previously learned codes.

3. Press/hold remote control and press/hold button of Homelink transceiver simultaneously. Slowly move remote control from 5" away to 1" away from Homelink transceiver. Release both buttons after red indicator starts blinking rapidly. This should take about 5 seconds. I discovered that the Homelink in my TL is a bit faulty because it took much longer to accomplish this than when programming the Homelink in my MDX. My TL's Homelink may "unlearn" it's code in the future and the needed proximity of the TL to the garage door may be much closer than desired until I get the Homelink fixed.

4. Press training button on garage door opener unit until the indicator lights illuminates- this should be immediate.

5. Within 30 seconds press/hold the Homelink button for 2-3 seconds until the red indicator starts flashing rapidly. Repeat a second time. It should now be programmed. Check it by pressing the programmed button on the Homelink receiver.

6. When programming more than 1 garage door opener unit, disconnect power from unit before programming more units. By not doing this the programmed unit could conflict with the unprogrammed units commands.

Problems:

1. The Battery in the garage door remote may be too weak to program Homelink. However, the battery may be strong enough to operate the garage door. One of my remote controls had a weak battery- my system was installed today, fresh out of the box. I had to use the second remote control for the programming of Homelink on my 2 vehicles.

2. Antenna on the garage door opener unit must be hanging down, fully extended.
