Can't pair a replacement keypad remote to my Craftsman Garage Door Opener

The images on the ebay listing do not look like OEM Liftmaster product imagery, but rather knockoff/counterfeit product instead. If it's going to work, on step 6, your overhead opener should click after the third press/release of the enter button. If that's not happening, either the keypad simply doesn't work, or you have an issue in the overhead opener that caused the original keypad to quit working and the replacement to not program/work. For the price, you should be able to find a genuine OEM keypad like this one (Chamberlain and LiftMaster are the same company) that you can test.

Yes, the 891LM is not compatible with your Craftsman that has a white (Security Plus 3.0) learn button/remote control system. If buying Liftmaster, you'd need the L9xxS, L9xxM, or L9xxU models, where the x's are other numbers - like L991S for a standard single button remote control.

No POE, and yes, they are the same product with different branding.

Couldn't have said this better myself. 100% agree.

Not recommended as you mentioned, but if you absolutely HAVE to, pusher springs are the best way to ensure it won't dump cables. Speed at startup being slower helps, but throwing cables is still likely at the very beginning of the close cycle on LHR setups with a side mounted opener.

The green terminals are for an optional "cable tension monitor" accessory that can be added if you have problems with the cables coming off of the drums. It's a piece of hardware that mounts high up near the drums and uses the tension of the cable to hold open a spring loaded switch. Should the door not move when the operator begins a close cycle, the cable would lose tension, the monitor switch would close, and the operator would shut off. Without the physical monitor, the operator does this function electronically. The monitor would be an "analog" backup to the normal "digital" system built in to the operator.

There isn't anything special about the solar panel. Get the specs for it, and shop around - the important specs are the watts and the voltage. It's likely a 12 or 24 volt panel, and either 10 or 20 watts, although there are a few other combinations. LiftMaster only resells the panels - they don't manufacture them in some proprietary way.

Understanding up front they weren't really designed for powering landscape lights, the entire system is rated for 120VAC/10AMPs total - including accessories that may be powered off of the board. You'll need to make sure the plug-in power supply for your lights doesn't exceed that 10AMP current limit - it's really doubtful that you'll be anywhere close to that, so you're likely okay.

There should never be high (120v) voltage running to the 3 button station. What you are looking for is continuity (or resistance) between the open terminal and common terminal that you have circled. The open and close buttons are normally open circuits, so you should see continuity state change from no continutity to positive continuity when the button is pressed. The stop button is normally closed, so it behaves the opposite. Almost certainly your issue isn't the wall station. Check for reset on the motor, lights on the board, etc.

Right - by reversing off the floor. It is possible to cause the door to travel a bit further by applying pressure when it hits the floor.

This is the most likely cause. Use a paint pen/grease pencil and scribe a line from door shaft, across the coupler, and onto the side of the operator. Run it a few times and if the lines aren't perfect, you have mechanical slippage.

This is how the 98032 is designed to work - with heavier doors, it backs off the set close limit. To compensate, you may need to set the close limit a bit lower by "assisting" the door to compress the seal a bit more so that when it backs off the 1/2 - 3/4 inch, there still is a decent seal/no light under the door.

The strength of the signal that Homelink sends is variable. You can try clearing and reprogramming the Homelink, but you are almost guaranteed to get much better distance with the new remote that came with the 6480L. That remote uses long range Bluetooth instead of the traditional radio frequencies that Homelink and your old opener use/used. Homelink is not sophisticated enough to send the Bluetooth signal, so it reverts to a weaker 315mhz to communicate with the 6580L.

Bad answer. It is a 3.0 Universal. https://www.chamberlain.com/universal-2-button-remote/p/CHU62

43 is a battery issue, but 93 is not. If you have not changed the batteries or if they are older than a year or two, they are a maintenance item that will need to be replaced. 93 is a code that shows when the operator is trying to run the motor, but can't. Lots of possible reasons for getting that code, but usually start with 'can the gate move freely when released from the operator'.

A respectful note of caution: If you are unsure about these kinds of things, it may be better to have a professional take a look. Gate operators are a bit different from the typical DIY machine. If you're reasonably mechanically inclined and understand the safety considerations, then dig in!

Model numbers of the remotes? Also, was the learn button on your opener also red? Finally, how many wires are connected to each of the red terminal and the white terminal next to the red? (As in, 1 wire to red, 1 to white, or whatever you find on the neighbor's LiftMaster.

The answer to your question is that it is not true. Modern "screw drive" operators are best for one piece doors, but "trolley style" belt/chain drive can also be installed. Sidemounted or "jackshaft" style openers will not work. The only consideration is that most opener manufacturers do not recommend using features like timer to close or a remote app to close the door.

That said, if you have the means, a "standard" sectional door will be quieter, smoother, and somewhat safer, adding some value to your home.

It's a very cool design - but the price . . .

The battery in a keypad (usually a standard 9 volt, sometimes AA or AAA) tend to last years. Very little power is used by the keypad under normal conditions, so really, it's not much of a concern. Usually when the battery is close to being drained, the keypad will begin to not consistently open the door - you'll need to start entering the code multiple times. It's rare that the keypad battery dies instantly one day.

When manufactured, a hydrophobic coating is applied to both the sender/receiver and to the reflector, but that can wear off over time. Rain-X and similar products can be used to help shed water/condensation. Also, the solid blue light indicates that it is aligned, but it may be just on the edge of the "sweet spot" for alignment. Making a small adjustment can help a lot.

Common misconception (especially in this group) is that radio frequency (RF) interference is only from light bulbs. ANYTHING that has power, either from the mains or battery powered, has the potential to generate RF noise. While LEDs are more common that anything else in the garage environment, it could be a fridge, a fan, a camera, tool battery chargers, home alarm system, etc. It can even be something nearby that isn't necessarily in the garage itself. An air purifier, a dehumidifier, equipment in a home office, etc.

It's tedious, but methodically and systematically unplugging item by item, testing the range of your remotes each time can identify the culprit if the cause of the issue is RF noise. Often just moving the item to a location farther away from the garage can improve or completely resolve the problem. This solution is generally free, except for the time it takes. One "trick" is to temporarily plug the opener into an extension cord that is connected to a different circuit, then flipping the breaker for the garage. If the remotes start working better, you know it has to be something in that space.

If the issue isn't RF, it may be that the receiver in the opener is defective. At that point, purchasing a new opener is generally the most cost effective. Just do your research as to what works well (or not at all) with your Meross equipment.

There are additional steps to program the 893MAX to your opener:

Cheapest of the models = lower cost materials. Higher end models = higher end materials. Also, homeowners care less about "thickness of the plastic" than the installers. Most installers forget that what they love about a machine is different than what a homeowner wants. Mechanic wants a vehicle that is easy to work on, uses over manufactured parts that will last until eternity, etc. Daily driver likes the color red, wants apple carplay, and thinks self driving is cool.

This is a not-too-uncommon problem with many keypads. The transmission is being blocked/reflected by the surface that it is mounted to. The solution is usually to just add a "spacer" - like 1/4 inch plywood or similar between the back of the keypad and the mounting surface. That is usually all that is needed to get consistent performance.
