Short answer
LiftMaster is the professional channel of Chamberlain Group, sold through dealers rather than retail shelves. The single most useful thing about a LiftMaster is the colour of the learn button on the back of the motor head, because that colour tells you the radio system, which tells you which remotes will pair and which will not. Most LiftMaster problems come down to the logic board, the gear and sprocket, or the safety sensors, and all three are still supported on units going back many years.
What makes LiftMaster different
LiftMaster and Chamberlain are built by the same company in the same plants, and the difference is the channel rather than the machine. LiftMaster goes to dealers and installers, Chamberlain goes to retail. That matters for a homeowner in one practical way: LiftMaster units are generally specified with heavier duty motors, longer rated cycle life, and dealer only accessories, and their parts are ordered through trade supply rather than picked off a shelf. The mechanical architecture is otherwise shared, which is why an era matched Chamberlain part will very often work in a LiftMaster and the reverse. The place where LiftMaster genuinely stands apart is the accessory ecosystem: myQ connectivity, wall controls with timer to close, battery backup on the models that carry it, and dedicated wireless keypads and remotes that pair by radio generation rather than by model number.
How to identify which LiftMaster you have
Pull the light lens or look at the back panel of the motor head and find the small coloured button, usually beside the antenna wire. That colour is the radio generation and it is the fastest diagnostic in the trade. Green or grey generally indicates the oldest units running a fixed billion code system at 390 MHz. Red or orange indicates Security Plus at 390 MHz. Purple indicates Security Plus at 315 MHz. Yellow indicates Security Plus 2.0, which transmits across 310, 315 and 390 MHz and is the current generation. A remote or keypad has to match that generation to pair at all, which is why a new remote bought online frequently refuses to program to an older head. The model number is printed on a label on the side or back of the housing and is what you need when ordering a logic board or a gear kit, because those are model specific in a way remotes are not.
The failures we see on LiftMaster
The three failures that account for most LiftMaster calls are the gear and sprocket assembly, the logic board, and the safety sensors. The gear kit is a plastic worm gear that drives the sprocket, and it wears out on chain and belt units after enough cycles, producing a motor that runs with a grinding noise while the door does not move. It is a repair, not a replacement, and the kit is inexpensive. Logic boards fail from age, heat in an uninsulated garage, and power surges, and the symptom is usually a unit that clicks without running or lights that flash in a pattern. Safety sensors fail from misalignment, sun on the receiver eye, and corroded wire splices in the staples along the jamb. A LiftMaster that will not close from the remote but closes when the wall button is held is telling you the sensors are the problem, not the motor.
Parts, and what actually interchanges
Gear and sprocket kits, logic boards, capacitors, trolleys, rails, chains, belts, wall controls, sensors and remotes are all available for LiftMaster units going back a long way, which is one of the real advantages of the brand. Gear kits and logic boards are model specific and have to be matched to the number on the housing rather than to the look of the unit. Remotes and keypads are matched to the learn button colour instead. Rails and trolleys are matched to the drive type and door height, and a seven foot rail cannot be used on an eight foot door without an extension kit. Because LiftMaster and Chamberlain share architecture, an era matched part from either brand frequently fits, and a technician who tells you an older LiftMaster is unrepairable because the part is discontinued is usually mistaken.
Repair or replace
A LiftMaster is worth repairing far more often than most brands, because the parts are available and the units were built to be serviced. A worn gear kit on an otherwise sound motor is a straightforward repair and there is no argument for replacing the unit. A failed logic board is a closer call, since the board on an older head can approach a meaningful share of what a new opener costs, and the rest of the unit is the same age as the board. The honest test is whether the rail, trolley, motor and safety system are all still sound. If they are, replace the board. If two or more of those are also worn, a new head is the better spend. The one situation where replacement is clearly right is a unit old enough to predate reliable photo eye protection, because that cannot be fixed by adding parts.
What the visit looks like
The visit starts with the door rather than the opener, because a motor is only asked to guide a door the springs have already balanced. The opener is disconnected and the door is raised by hand and checked at several points for balance and smooth travel. If the door is heavy or binds, that is dealt with first, because a new gear kit fitted behind an unbalanced door wears out again. With the door confirmed, the learn button colour and model number are recorded, then power, wall control, remote response, sensor alignment and low voltage wiring are checked in order. The specific failure is explained before anything is replaced. After the work, travel limits are set without driving the door into the floor, and force response, sensor interruption, manual release and automatic reversal are each tested.

My new LiftMaster remote will not program. Is the opener broken?
Almost certainly not. The remote has to match the opener's radio generation, and that is set by the colour of the learn button on the motor head. Yellow means Security Plus 2.0, purple means 315 MHz Security Plus, red or orange means 390 MHz Security Plus, green or grey means the older fixed code system. A remote sold for a different generation will not pair no matter how many times you press the button. Check the colour, then match the remote to it. Universal remotes exist but they still have to cover the right frequency.
The motor runs but the door does not move. What is that?
On a LiftMaster that is usually the gear and sprocket kit. A plastic worm gear drives the sprocket, and once its teeth strip the motor turns freely while nothing is transmitted to the chain or belt. You often hear a grinding or whirring rather than the normal drive noise. It is a repair rather than a replacement and the kit is not expensive. Before fitting one, the door should be checked for balance, because a heavy door is what wore the gear out in the first place and it will do it again.
Are LiftMaster and Chamberlain the same thing?
Same company and largely the same machine. LiftMaster is the professional line sold through dealers and installers, Chamberlain is the retail line sold in stores. LiftMaster models are generally specified with heavier duty motors and longer rated cycle life, and carry dealer accessories, but the underlying architecture is shared. In practice that is good news, because an era matched part from either brand will often fit the other. Remotes still have to match the learn button colour rather than the brand name on the housing.
My LiftMaster closes with the wall button but not the remote. Why?
Holding the wall button overrides the safety sensors, so that exact behaviour points straight at the photo eyes near the floor. Either the beam is being broken, the lenses are filmed over, or the two units are no longer aimed at each other. Sun striking the receiver eye in the afternoon does it as well. Wipe both lenses with a dry cloth and check the brackets are square. If it persists, the wiring is worth checking, particularly the staples along the jamb, which cut into the insulation over years and cause intermittent faults.
