7 Quick Tips for Buying Garage Door Opener Parts

  1. You will need to know several details about your garage door opener to select the correct parts for it. Manufacturer name and model number are usually necessary.
  2. To find detailed infomation about your garage door opener, look on the garage door opener power head located on the ceiling of your garage. Usually stickers and identifying information are found on the back or sides of the machine.
  3. Garage door opener manufacturers change the frequency at which remote controls and keypads function periodically, so you will generally need to know the model number of your garage door opener.
  4. Some models of garage door operators use radio gear (remote controls, keypads) from another manufacturer. In this case, you will need to know additional details found on a currently working remote control.
  5. Use our Garage Door Opener Selection Guide for details specific to your brand of garage door opener.
  6. On each product page there is a section called "Compatible with". This section gives details on manufacturers and models numbers that use the particular garage door opener part, remote control, keypad, gear, or other part.
  7. If you are still not sure which part will work with your garage door opener, Contact Us using the web form on the contact us page. Please include details about your garage door opener manufacturer and model number in your question.

Great Way To Save From Buying A Whole New Garage Door Opener
  Very happy with this product. This was a great find and helped us save $$$ from buying a whole new product. Just to let you know that ours had a press fit, not hard to do, but you need to know how to do it.

  Unable to get the lower retaining pins out, so I removed the chain and pulled out the top drive unit and placed it into my large vise. After chipping away part of the old plastic gear, the pins released. With the upright unit out it was easy to insert new drive gear and pins. Reinserted unit onto worm drive and reconnected the drive chain. Lubed in place and reconnected the worm stop system..minor adjustments to up & down. Works like a charm...quite a saving for a retired guy!

Perfect Replacement
  I installed 3 in the last month and they all fit perfectly. One was in my house I am getting ready to sell and two in another house we just bought. By the third time,I learned the shortcuts and it was an easy install. I suspect most people would have bought a whole new garage door opener, but this worked perfect.

Do this
  Don't hesitate, just do this...much cheaper (and far easier) than replacing the whole opener. Fast shipping, and great "shortcut" instructions that make installing this real easy. One note: put a rag behind the pin when driving it out, it will fly out of there and across the garage and you'll be off to the store for a new one if you can't find it. Thanks!!

  This gear performed as advertised and was easy to replace the failed gear. The delivery was way better than promised. WD was the only source for the single gear. Others wanted to sell a total assembly that was not needed.

Good Service
  Good product. I ordered the plastic large gear and it came as ordered (new with lubricant. I was hoping to get more lube, but no worries, you have to be careful to squeeze every drop out of it. Anyways the part was installed and the garage door started working again.

Thanks!
  I placed two orders with this company. Both orders were handled most expeditiously by both your company and the postal service. Five stars. The replacement garage door opener large drive gear replaced one that had been in service for some twenty years! Perfect fit and very, very easily installed. Five star. I just wish every transaction of mine went as smoothly as these ones.

  Gear was delivered quickly. Did not realize that there would be so many parts to remove in order to replace the large gear. Could have replaced all the gears, but they were still good. Looked up a you tube video on how to replace the gear. Put my lap top on a shelf near the opener and followed the video, step by step. A potentially difficult job for a first timer made easy. Garage door opens and closes perfectly.

Detached Garage Door
  I was able to fix my garage door opener by myself, thanks so much to YOUTUBE and WayneDaltonParts. I already returned the new garage door opener I purchased which I thought was the only solution. This plastic gear worked like a champ so I bought a couple extras for my other garage door openers just in case. BE SAFE!

Great Price and easy to install.
  This little plastic magic gear got the garage door opener working in no time. Easy to follow instructions. They should have mentioned it was easier to move the gear in position by turning the motor shaft out of the back of the motor. All in all a great easy repair.
