Mine came with one 3 button remote
A little off the subject, but have you installed yours yet? I just received mine and was told by a garage door company that they prefer it have a solid shaft than a hollow shaft. Mine is hollow and will be spending an additional $80 to buy a new one.

The remotes will work from newer liftmaster chamberlin openers.
I set up a second button on one I had on an existing oh door.

Hollow vs solid shaft on the opener? Why the difference?

Mine has been working just fine on a heavy wood door with hollow shaft from the 70's. Door is well balanced though which is key with these openers.

The collar clamps to the shaft with one set bolt. I'm sure they want a solid shaft so you don't crush the shaft.

if the door is balanced, i see no excessive torque happening on the shaft. The torsion spring eliminates the torque.

First I've heard of that! Just pulled up the Installation Instruction Manual, nowhere does it state that it needs to be a Solid Shaft!

I have hollow shafts and two side mount liftmasters. I haven't had any issues nor have I heard of any issues related to that. Seems like overkill...you could also put a short filler rod inside the shaft and avoid the trouble I suppose.
Also consider this: The torsion springs carry 90% of the door load and see MUCH more loading than the opener does... their set screws hold the hollow shaft just fine - I don't see why the opener needs to have a solid shaft but the springs don't.

Sounds like the guy is "shafting" you
I have 3yo door and 3800 opener. I would assume it's hollow. I have never had an issue and we use it like the front door!

Just had 6 of these installed, all with hollow shafts. One opener included for each door. They threw in 2 outside wall mount remotes. One for each set of three doors.
Get the internet gateway. It's a one time $50 charge and set's up in less than 5 minutes. You'll love it. Was headed up to bed last night, grabbed the iPad and saw I had left a door open... one tap and off to bed!

The 3800/8500 definitely does not require a solid shaft. Commercial jackshaft openers require solid shaft, but the residential unit is designed to work with standard 1" hollow shaft. Don't waste the money. In fact I almost want to say that they prefer you not to use it with solid shaft.

These are Not to difficult to install provided the electric is nearby, and your door is opening properly, balanced, etc...
If you are so inclined. It took me a little while to set the door stop limits, in December I was trying to rush and skipped a few steps b/c I was cold!

I found out about the 8500 from lurking on here. Just installed mine a few weeks ago on a 12x12 with hollow shaft. Took about 2 hrs. Works great. Only problem was the remote that came with the 8500 wasn't programmable to my other liftmaster opener. I had to pick up a Chamberlain remote at Lowes that I could program both different doors too.

The charge was to purchase the gateway. I wasn't as clear as I should have been. There's no subscription to use it.

Can the liftmaster 8500 be used on either side of a garage door? Thanks

I just bought two of these. Anyone know the watts of the motors when they are running? I want to plug them on my 15 AMP "Lights Breaker" for nine T8 shop lights and a four LED outside lights.

If I recall the motors are 24v so there is an inverted in there somewhere. I think you will be five running off light circuit. Thats how most residential garages are anyway

A quick observation yesterday with one of our 8500s: The garage door was open and it was windy outside. As the door came down, the manual release cord was blown between the track and a guide wheel. This immediately stopped the motor and released the door. I had to lift the door up to release the cord, and then reengage the manual release. No big deal, but weird.
I'm sure this was a one in a million chance, but decided I'll put some velcro on the handle and stick it to the wall to avoid this in the future.

Ok great, thanks again. Yea my old Liftmaster openers is from 1993 and uses 540 watts to run each. These are a big improvement for sure.
