liftmaster 98022 and 841LM lock

[yellowfever]

Hello,
Recently installed Liftmaster 98022 side opener which came with 841LM deadbolt style locking mechanism. While I like the security part, the noise is pretty loud and concerned with eventually failing when I need to open the door.

My understanding is you can just unplug this from the 98022 to disable this? Just wanted to make sure it won't cause any issues without being connected. More importantly, I presume someone can't just open the door because of the tension on the jackshaft style opener?

Thank you!

Not my picture but in the middle is the locking mechanism.

Give it a shot and let us know.

The full weight of the door is working against whomever wants to open it.

The lock shouldn't be required. I moved my 8500 lock to the LJ8900 and both worked fine. I got tired of manually locking the 8500 door and bought another lock.

I have 2 of them. I like hearing the loud noise as I exit the garage. It's reassurance the lock engaged.
How heavy is your door?
I don't recommend trying to lift it as a test - the cables could tangle - unspool etc.

 

[yellowfever]

Thank you all! My door is about 300lbs so it's pretty heavy. My previous opener (also Liftmaster) didn't have this mechanism.

^^^This right here, along with the added security.

I'd be surprised if the MyQ app doesn't trigger based on the mechanism, but let us know.
I have two of these things, one installed for 4 years, it's quite satisfying to hear it lock and it has not failed. Compared to my traditional openers, it's been 100% trouble free without a single adjustment needed.

Love that thunk! Know the door is down and locked. Had trouble with the door stopping at the floor and then going back up but that was resolved after some 6 service calls by replacing the entire opener,

Lock not needed for anything to work properly, leave it in box…MyQ does not care….door is “held down “ by opener, unless you pull the clutch release cord, not going anywhere…..

Nope. This is a jackshaft opener. It will not hold the door down. The weight of the door is the only thing holding it down.

Well in that case there is almost no weight on the door, due to the spring being set for the door to hand open.

I believe the unit does keep it from being opened, as that is why there is a release to disengage to open in the case of a failure.

The spring doesn't assist when the jackshaft isn't allowed to turn. To operator holds the jackshaft stationary, meaning the weight of the door is all that holds it down if the deadbolt isn't employed.

I have 2 openers of this style since 2008. One door is used many times/day. That lock failed after about 12 years. Dead bolt would not fully retract for door to raise. I manually retracted it fully and electrically disconnected it while awaiting a new dead bolt. No issues operating like that.

Yes, you could open the door without the deadbolt in the locked position. As mentioned, the cables would would unwind from the drums and make a mess of things.

Buy a spare now if you are that worried about it. Simple replacement.

I hope you have a 2nd means of access to the garage.

Chain driven openers prevented the door from moving in either direction as it was "locked" by the opener sprocket which wouldn't turn. Cables however, only provide tension and no compression. Compression capability would be needed to prevent the door from opening w/o the jackshaft rotating.

I bought this style opener about a year ago. If they weren't so expensive, I'd buy them for all my garage/shop doors!

I left mine in the box and set up the safety beam near the top of the door. We are fortunate to not have to worry about security of our stuff so no locks needed. I never set up the MyQ app either, hit the opener couple hundred feet from the shop.

I think we are saying the same thing, I just phrased it poorly.

The person I quoted indicated that since it was a jackshaft opener it wouldn't hold it closed, only the weight of the door holds it. I was trying to say that the door has almost no downward weight when setup properly, and that the jack shaft opener does in fact hold it closed hence the release.

Dave is right though. The jackshaft operator doesn't hold the door closed; it just holds the jackshaft. The effectively unsprung weight of the door holds it closed, along with the deadbolt, if installed. A more standard overhead operator, be it chain, belt, or screw-drive, actually holds the door closed instead of holding the jackshaft stationary.

As said before, without the deadbolt lock, you can lift the door if you are strong enough. You won't be assisted by the torsion springs.
Pulling the clutch release unlocks the jackshaft from the opener. If you to that, the springs will assist you in lifting the door.

If the clutch is engaged the jackshaft can not turn. Lacking a deadbolt, lifting the door will cause the cables to slacken and likely come off the hubs and snarl. But I suspect a thief will not care about that.

The opener without the deadbolt has no way to HOLD the door down. Gravity is all you have.

I see what you are getting at.

With said i was thinking of my insulated doors which are heavy, no way you are lifting them without some spring assist.

I will say I like the deadbolt noise, I can I can tell if the door has opened for some reason, and same when it closes.

 

[Mikes61]

Is there no lever on the deadbolt to manually slide the deadbolt pin out of the way? Can you push it from the end of the pin, back into the housing?

I have Genie jackshaft openers and they have a lever that you can slide the locking pin back and forth with.

It has the manual lever.

 

[Mikes61]

End of concern then, correct? Or did I miss something?

The OP will have to tell us.

You are correct, I am not lifting them. Two motivated burglars against the OP's 300 lbs. door, needing to lift door high enough to crawl under it have a much better shot at lifting a door than I.

In my case I suggest they walk around the side of the house and smash the window in the man door. And as I said earlier, I find the deadbolt noise reassuring that they will head that way. Security is not about an individual weak point.....

But more importantly as I turn my back on the door and walk away, I know it did not reverse against my wishes.

For grins, I just tried lifting the door to my office after disengaging the lock. No can do. It looks like the jackshaft "disengages" the spring because I get slack in the wires. Could it be forced open? Probably....

It absolutely disengages the spring. Some doors are heavier than others. And lifting the door can make a mess of the slack wires.

Did you try lifting by hand? A little leverage goes a long way.

Just for grins based on this thread, I tried lifting it by hand. I could move it a bit. I didn't didn't give it the full try... It's also probably a heavy door (mostly glass)... I suspect it would open if enough force was applied.

I like the locks on the jackshaft opener, and since there is a provision for a second lock, I have added one. I also have a device that indicates when the door is open and beeps every 15 minutes to remind you. There are no outside handles on the door itself, and that alone will make lifting my door difficult for any burglar, unless he/she is strong like Atlas.

Or this, the black hat is optional:

 

[Skooterj]

The jackshaft opener keeps the torsion bar from spinning, which stops the springs from helping to lift the door. But a guy with a pry bar can get it off the ground easily. And then could get a jack under the door and lift it enough to get inside. Or 2-3 guys can lift most doors. You need the lock, but the lock has a manual override. All you have to do is slide it, which is why you are supposed to put it close enough to the ground you can reach it. The opener works just fine without the lock, but the only downward pressure is the weight of the door. Give me a long enough lever and I can move the earth.

For a tool based forum like GJ, I'm surprised how many people mentioned trying to lift the door by hand instead of using a lever.

ive had one for 18 years, it just failed 2 years a go. i just cut the wires and probably wont replace it. worked flawlessly up until then.
