The garage door opener is not as durable as you think it is. Although it made to last you and your family years of regular use, it is also subjected to wear and tear. You may encounter various problems and issues with your garage door opener through the years. When this happens you can either troubleshoot it yourself or have it fixed by a professional.
When troubleshooting, the first rule is to find the symptoms and do the proper inspection after. Every symptom leads to a certain cause or problem. One of the common issues for garage door openers is when the door doesn’t open or close but makes grinding sounds.
Test it out first
Grinding noises can either be caused by the garage door or the opener unit. Make sure that you do proper testing to find out what is really wrong with your opener. First, disconnect the opener and open the garage door manually. If it still makes the same noise, then the problem is with your garage door. On the other hand if you cannot hear the noises, then it must be your opener.
Genie opener problem
Grinding noises are typically caused by problems inside the opener. It may be that the motor is on its way out. It is also caused by stripped plastic gear. Both of these can cause that same grinding noise. If you have a Genie screw drive opener, then this might be caused by the problem with the coupler.
The motor shaft is connected to the rail screw and the coupler. This lets the motor turn the screw, which in turn moves the trolley to open or close the garage door. When the coupler gets worn-out, it doesn’t open or close the garage door.
Replacing the coupler
To fix this issue and replace the broken screw drive coupler, follow these steps:
+Prepare the opener. Unplug the opener from the power source and remove the light lens plastic cover. This ensures that you won’t get shocked when fixing your opener and that nobody will accidentally open it while you are working on it. Remove the screws and disconnect the rail from the opener. Loosen the bolts and unscrew the shoulder bolts. Remove the rails from the opener and secure it from the ceiling with a rope.
+Replace the old coupler. Locate the old coupler at the back of the opener. You will find that it is worn-out already. Remove it and replace it with a new one. Insert the new coupler and rotate it in place with a screwdriver.
+Replace the rest of the parts. After you’ve inserted the new coupler, use needle-nose pliers to rotate the tip of the screw shaft in order to align it with the coupler. Reinstall the bumper into its slot by sliding it back into the groove.
+Reattach the rail. Slowly slide the rail back into the garage door opener. Insert its bolts and screw them place. Make sure every nut and bolt is secured. Reengage the opener and plug it in.
+Test the opener. Once everything is ready, test it to see if it is working as it should. Push the wall button to open and close the garage door. If the troubleshooting is successful, then the opener should function. Then, reattach the light lens cover if the door is working fine.
If you are not confident doing the manual work by yourself, then it is best to hire someone to do the work for you. This saves you time and effort, especially if you are too busy to do everything by yourself. Doing so also ensures that you do not miss anything and that everything should work fine. If you like being handy on the other hand, then it might be fun for you to troubleshoot it on your own. (Video below by AdamDIY)
