In this section I have briefly discussed 3 common issues with the Liftmaster 3800 along with how to solve them. If you are still confused go to the next section for a more detailed fix of these three problems. 

Problems Reason Solution
The control console and remote control are both ineffective  The opener may be disconnected from electrical power. Door locks may not be disabled. The door may be frozen to the ground. The garage door spring may also be broken. Check if the Liftmaster 3800 is receiving power. Disable the door locks. Remove any snow or ice near the door. 
Cocked Doors with Bent Rails cable on the opposite side of the device disconnected from the drum Tighten the set screw on the left side pulley, compress the spring and then tighten the right side shaft.

So, that was a quick solution to fix the typical issues that consumers run into with the Liftmaster 3800. If you are still confused please do not worry. In the next section, I have a thorough explanation for each of them. 

The Control Console And Remote Control Are Both Ineffective 

Sometimes you will find both the control console and the remote console unresponsive.


Follow these steps to quickly fix the issue:

  1. Check if the power outlet the Liftmaster 3800 is connected to is outputting power. To do this connect any small electrical appliance to the outlet and run it. If you are using a double socket one side may not be working.
  2. If the door locks were not disabled and ropes were not removed during the installation process do that now. 
  3. Remove any ice or snow piled up near the door. Also remove any obstacles that could keep the door from opening.
  4. The torsion spring located at the top of the garage door may be broken. Replace it by calling a professional Liftmaster technician.

Cocked Doors with Bent Rails

A common problem with the Liftmaster 3800 is that the garage door gets cocked and the rail gets bent. This happened as a result of separation of cord on the other side of the device from the drum.


To address the issue, slightly raise the edges of the tracks. Additionally, the door should be positioned with a slight downward angle while it is in its resting position. It is important to note that the Liftmaster 3800 model is designed to only guide the door as it falls. It does not apply downward force to the garage door.

Follow these directions to solve the problem:

Step 1: Without exerting any force, position the spring.

Step 2: Then tighten the left hand side pulley by hand and also tighten the pulley’s set screw.

Step 3: To maintain the cable taut, compress the spring by one turn.

Step 4: By hand, tighten the right-side shaft and the shaft set screw.

Your garage door should now be opening evenly. Alsom check out the manual for further inquiries.

Partially Open Door Before Shutting 

The door opens for about 2 inches before halting when you press the door opener button. When you press the door opener button once more, it partially opens before shutting. 


The issue might be resolved by adjusting the “up force.” you need to adjust a knob where all those white cables connect to the machine’s back.

Reach up there and make an adjustment to the up force by rotating the knob clockwise slightly. Check if the upforce is sufficient by opening the garage door. If it is not adequate, keep adjusting the knob until the garage door opens properly.

Blocked / Jammed Door

In this case the door gets stuck during the downward movement, and you will find it hard to pull it down manually.


To ensure smooth operation of your Liftmaster 3800, you need to remove the roller connection. After that lubricate the rollers or replace them and keep the track clean. A properly working door is also essential for its operation.
