What is the difference between the Liftmaster 893LM & Liftmaster 893MAX?
897399
I believe the 893LM only works on just LiftMaster doors, the 893MAX works on Liftmaster plus, Sears, Chamberlain, SteelCraft with 315Mhz or 390Mhz frequencies.

The Max is also compatible with the MyQ internet gateway should you have that accessory which allows you to use a smart phone to control your garage door. One word of caution, if you still are using an old 1 button remote with the newer technology 3 button version, you could have a problem. I got a 3 button remote and continued using an old 1 button one. I began having phantom operation of the door (opening and closing on its own). After 2 months of trouble shooting, found out the remotes use 2 different technologies and having both programmed in the unit has the potential of causing a phantom operation due to conflict from having both types. I ended up returning the 3 button and getting a single button.

That is all you need to upgrade your liftmaster door made after 1997 to myq. the 829lm is an optional sensor if you want to see door status from inside the house like a bedroom.

Correct. You need one 888LM to replace each old opener button and you only need one gateway to plug into your router. They will work with any Liftmaster or Chamberlain opener 1998 or newer. The only difference between the Chamberlain and Liftmaster controllers is the nameplate, so buy the best price.

Sorry, I couldn't say, I just have a basic Stanly door. The Liftmaster 3800 does a great job.

I purchased the Model 8500 which shows the 475LM as an option. I looked up your Model 2580 instructions online and didn't see the 475LM as an option for your opener. I would call the manufacturer just to be sure though.

Yeppers - Dat be da one! Your Craftsman mdl. 139.53985dm unit looks identical to my Liftmaster unit, (which, no doubt, looks identical to someone else's Chamberlain unit) - all from the same factory floor. Leave it to Sears to impose name-brand crossover restrictions on their vendors, just to make life harder on their customers.

Yes, the Liftmaster 535LM commercial receiver works well with the 890max key chain remote. The important thing with the 890max is when programming it, make sure when you hit one of the three front buttons to match the frequency, and if it does not match with the first button press, release the 890max button and press it again. Do not rush. Be methodical. It is looking to match to the right frequency and it may take a couple tries within the time period that the "learn frequency" LED is lit.

My Liftmaster calls for a 376 but it is no longer available. I took the chance that mine was also 315MHz and it worked fine. I also have the same color button. Hope this helps.

Hey Marilyn- Your operator can use a few remotes. The 973lm would be the 3-button remote that you'll need. The manufacturer has begun making them obsolete but you've got a couple of options. The 893max for 3 - buttons or a universal 375lm for 2 - buttons would work great. Please let me know if you have any further questions. Thanks...Matty

I have the 886 and it works great for me on the various jobs I have used it for around the house. It does have a variable speed so you can control the speed yourself. This works fine for me. I believe the 3 speed on the 895 model is better suited for commercial applications where you want to have the rpm set for a particular range. I will tell you this the brushless motor in both of these models is fantastic...the battery charge lasts a long time. Hope this helps you.

This unit is designed for the Liftmaster 3800, 3900 and 8500 series. It connects directly to the opener via a small plastic connector and does not need any programming. The bolt is activated to retract just prior to opening the door and extend after the door is down. It's pretty reassuring to hear that "clunk" and know that the door is locked tight. You may also manually slide the bolt if needed (i.e. power outage).

Hello, it's hard to say. I have Chamberlain garage door openers, and it works just fine with the Liftmaster 973LM.

There is no difference. HL10 is the product number for the lifter. Some websites just word the description differently.

As far as I know, the only difference is one comes with a bracket (803) and one doesn't (801). Also, some folks say that one # is an older part #, fyi.

Here's the manual for reference.http://www.liftmaster.com/CatalogResourcesV3/en-us/shared/files/tucmanuals/114A3930.pdf

I have a 15 year old Liftmaster opener and the remotes stopped activating the opener. I bought 535LM receiver and wired it per the directions and it works just fine. I mounted it by the door, so now i have two places with "push button control" and the receiver is closer to the outside wall which improves the reception from my HomeLink car transmitter. Be sure to by the transformer (they should package it with the receiver as most installations require the transformer).

The One is a newer better design in my opinion, but other than design differences the only true functional difference is that the 890 has RF.
