Common Problems of LiftMaster 3800 and Solutions 

Everyone wants a gadget that will give the maximum degree of protection for their home. The LiftMaster 3800 is the gadget that keeps your bets safe and secure.

But just like garage light wiring, it also has some common problems that users face. I have them listed with their simple solutions.

Cocked Doors with Bent Rails

The rail is twisted and the door is cocked. Because the cable on the other side of the device broke loose from the drum, this occurred. You may attempt to repair them manually. 

The wire, however, may fall off the drum after multiple usages.


It may be fixed by gently lifting the edges of the tracks. At repose, the door should be at a modest downward angle. You can hide the tracks if you want. 

Keep in mind that the Liftmaster 3800 does not force the door down; instead, they just guide it as it descends. 

When installing, follow these instructions:

  •  Put the spring in place with no strain.
  • Hand-tighten the left-side pulley, then tighten the set screw on the pulley.
  • Compress the spring by one turn to keep the cable taut.
  • Tighten the shaft set screw and tighten the right-side shaft by hand.

Tight up the spring with the appropriate number of turns, as indicated in the handbook.

It might have occurred as a result of cable slack. Make no attempt to outsmart Liftmaster. 

Don’t  Skip the cable tension sensor. It might lead to the same cable-off-the-spool issue.

The cables will loosen if the door won’t lower on its own while the opener rotates the cable drums. The tension sensor is used for this purpose. 

The Liftmaster is vulnerable to these factors, but once configured, it is dependable.

The Door Opens Slightly Before Coming to a Halt

When you hit the door opener button, the door opens for approximately 2 inches before stopping. You push the doorbell again, and it shuts before fully opening. This is a regular issue with the List Master 3800.


The ‘up force’ may be adjusted to fix the problem. It’s around the place all those white cables go on the back of the machine.

Reach up there and adjust it carefully. Adjusting the up force should do the trick. Also, you should make sure the rails are leveled.

Jammed Door

On the way down, the door is jammed. When you attempt to pull the door down manually, it jams right away.


Disconnect the rollers from the doors. Once you’ve finished your floor, lubricate or replace them.

As previously stated, the door must be able to roll from fully open to fully closed while supporting its weight. There is no binding of any kind.

Make sure the track’s horizontal section is as square as possible. Last but not least, for a 3800 to operate, you must have a properly functioning door.
