Right Parts All the time---Super prices
I had to have a speed sensor for my garage door opener to complete my rebuilding project of 2 openers at my house. All said and done with all parts ordered through WayneDaltonParts.com I have spent under $100 to do the job correctly. I will tell you from experience if you are changing gears out, go on and change the worm gear out and bushings then you know the job is 100% right. Some folks suggest not changing if it does not look worn, if the gears are worn out the worm drive is shot. I put everything back together adjusted chains and tension lubricated rails and chains and tracks and realigned them as well. Let me say both of these units are as quite running as they were new. So do the math Rebuild and clean a unit for $45 bucks vs. buying a new one? Thank you Jennifer at Wayne Dalton Parts for your service help! Kenneth Jones

The parts appear to be as good if not better quality than the OEM. The service ie ordering, tracking and shipping was exceptional. My experience with them could not have been better. I am not one who normally would write a review like this but felt obligated in this case due the outstanding experience.

If the door moves less than a foot in either direction, then this is the part you need. Fits all models that look the same. You do have to replace both the chip and the round cap - new style is slightly larger in diameter. Two minute repair.
