Genie Screw & Trac Drive Garage Door Opener Replacement Limit Switch 20113R

My old switch was failing which caused the garage door "arm" to crash into the door opener mechanism.Easy fix that most could perform.

identical to my original from 34 years ago garage door operates like when it was new works with blue max opener worm gear drive best openers ever made to my opinion all my neighbors have the same openers approximatelly installed in the early 90s and they still working a few neighbors diceded to replace their openers because of the auto stop swiches going bad and now the wish they would replace these swiches companies stop making screw drive openers

My Genie SD9000 model screw drive type garage door opener was installed in 1991, so it is basically 30 years old. I noticed my garage door started to run passed the maximum opening limit, and it just turned out that the wire spring on the open limit switch was bent and the plastic lever was also broken, so the limit switch needs to be replaced. I repaired the broken limited switch a bit so the garage door can be in operation as a temporary fix while waiting to purchase a new switch. I still keep the original owners manual on my SD9000, which shows the limit switch part number is 24454R, however, there is very little information on the 24454R, only a few sellers carry the limit switch with this part number. Although some have an interchange part number but none provides a definite description or statement to clarify that 20113R.S is the new replacement part number of 24454R. Worst, I checked the official Genie's website which says 20113R.S will not fit SD9000 or any SD Series. I then called Genie's tech support which the tech support person said that SD is very old, so they do not have any information on 24454R, and that Genie does not sell it or have the new replacement part number. Luckily I saw in the Q & A for this seller that there is one SD9000 owner said 20113R.S fits his garage door opener, so I bought two. The seller is very good, the shipping is fairly quick from Florida to California, ordered on Monday and got it on Friday. Yes, 20113R.S replaces 24454R and it does fit SD series garage door opener. The installation is very simple like everyone said. Lubed the screw track and my garage door opener now works great.

I just bought a 60 year old house that had two 30+ year old Genie garage door openers. The owners of the past 8 years were mechanically disinclined to the point of comedy, so much so that the broken uper limit switch on one of the door openers was replaced with a wine bottle cork at the extreme end of open travel. The *thunk* would wake my kids and trigger seismographs 50 miles away.This switch worked perfectly. Like other reviewers, the hole for the set screw was tight and unthreaded, but nothing that simply driving the screw through the hole didn't fix. Doesn't come with instructions, but didn't need too, but since it might help others (such as the previous owners of my house), here's some instructions:AS ALWAYS, REMOVE POWER FROM A DEVICE YOU'RE WORKING ON BEFORE YOU WORK ON IT.1) Observe the limit switch you're trying to replace, noting which side of the track the trigger is on and where the wires attach. For installing the "open" switch, close the garage door, and for the "close" switch, open the garage door.2) Remove the old limit switch, noting where the trigger was on the track.3) Insert the new set screw in the new limit switch hole. This requires a nut driver as the limit switch is not slotted. Thread it through the hole plus an extra turn.4) Stand on a ladder, milk crate, or other device such that you can get to the top of the track.5) Place the limit switch on the track with the "trigger" side on the proper side, with the trigger at the same position as where you noted it previously.6) Firmly tighen the set screw, do not over tighten as this may cause the trigger switch to rotate away from the spring on the door opener trolley. Plugh your garage door opener back in,7) Check the operation to make sure your garage door limits are acceptable.8) Since you're now knowledgeable about the limit switch operation of your garage door, adjust the other switch if you need too. On mine, the downward switch had moved, meaning the garage door would *thunk* when closing too. Moving it 1/4" up the track eliminated the thunk yet the door still closes all the way.The level of mechanical skill required to install this switch is virtually zero, however, as noted, a nut driver is required to install and tighten the set screw. No electrical knowledge is required, however, you have to remove the wires from the existing switch and install it on the new switch.
