    I do not have the door engaged at all. There is no pressure on the motor. I am simply trying to check the motor. The springs are fine and I have already adjusted the force adjustments. Any more checks that anyone can assist me with?

First look the springs on the door. It is possible that you have a broken spring. If the springs are not broke, look at the force settings. They should be about half way.

    Take the cover off the opener and check to see if the gear is stripped. The bottom of the cover will have a lot of white flakes laying in it if the gear is stripped.

I have a genie pro 88 garage door opener push the button and it opens just fine traviels up to the limit switch and stops perfect. then push the button to go down and nota,


are the wires connected to the motor correct
for the limit switch there should be one wire ( normally black or neutral going to the center connection and the other wire ( red or active wires going to either of the other two terminals
that set up means that power is available to the limit switches and the return is the neutral wire
it works like this
on the up direction power is delivered to the motor by the controller box through a closed limit switch
when the up limit is circuit is broken the motor stops
the down button reverses the polarity of the motor in the controller box and so the motor runs in reverse through the the lower limit switch until that circuit is broken In the down action the upper limit switch circuit is completer but the control box has no power to it until the lower switch circuit is brokenis broken
the motor is dc voltage and to getting it to go up or down is done by the control box changing polarity for the motor power according to the button position pressed on the remote

After connected to the power, the courtesy light flashed 2 times and the up and down button on then off. I pressed up, down and programme button, no respond. What should I do?


It is likely that your unit is equipped with a remote control lock out. When the lock is enabled the remote will not work protecting the home.

The Lock Button on the Door Control

The lock button on the door control may be activated. Press the button to turn this feature off. The light bulb will blink two times. This feature is designed to prompt you that the lock button is activated. When the lock button is ON the garage door opener will work from the door control but the remote controls are locked out.

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.

My Champion garage door opener opens by itself and the light does not come on


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


If one of your neighbors remote controls is inadvertently programmed into your receiver, you door will open when their remote is activated. If this happens you will need to clear out your receiver and reprogram your remote controls. Press and hold the smart/learn button for 6 seconds or until you see the small LED light near the button turn itself off. If the above steps have been followed and the symptoms continue, there may be an electronic short in either the wall control button or the receiver logic board. In this case, remove the wall control wires from terminals 1 and 2 on the motor unit. Should the symptoms persist after the wires are removed, replace the receiver logic board. If the symptoms stop with the wall control wires removed from the motor unit, replace the wall control button, and the wires leading to the wall control button.

Where to buy remote control and reset My garage door opener also


To erase the memory of the opener so that your old remote will no longer work you need to locate the smart/learn button on the rear of the motor unit. Press and hold this button for 6 seconds. No remotes will now work.

To program the new remote when you get it, hold the button down on the remote and then press and immediately release the smart/learn button.

Call any local door opener repair company from the yellow pages and you should be able to buy a remote from them.
