In this next video in the Liftmaster 3800 installation instructions, Dave will take us through the steps of installing the smart control panel.

The first step is to strip the wire.  Then connect the wire to the control panel as Dave does in the video, noting the markings on the panel “R” (red), and “W” (white).

Finally connect the smart control panel to the garage door frame.

Please remember to refer to your Owner’s Manual in addition to this video.

In this video we will connect all of the wires to the Liftmaster 3800 motor unit.

The first step is to route the wires from the safety sensors, the cable tension monitor, the lock mechanism, and the smart control panel to the Liftmaster 3800 unit.  As noted in the video it’s a best practice to use crown staples to fasten the wires to the door frame so they look neat and don’t get pinched.

Next Dave will open the lid of the 3800 control unit and begin to terminate the wires to the terminal strip in the unit.  In addition to using this video as reference please refer to the LIftmaster 3800 Owner’s Manual to ensure proper wire connections.

Once the wires are properly connected you can then plug in the Liftmaster 3800.  Then re-connect the disconnect of the unit.

In this video we’ll complete the set up of the Liftmaster 3800 garage door opener ensuring that the upper and lower limits are properly set, as well as the force adjustment.

In the first step Dave slides out the plastic protector in the 3 button remote to activate the unit.

Next Dave will set the travel limits of the garage door.  Please follow the video instructions and refer to your Owner’s Manual.

First Dave will set the limits of the “Up Position” of the door.

• Press and hold the black button until the yellow indicator light starts flashing.
• Press and hold the black button until the door reaches its desired up position.  Please ensure that you set the door high enough for your vehicle to travel under.
• Next press the remote control or smart panel button which will set the door and begin the door decending.
• Push the purple button which will stop the door and you’re now able to set the down position.  Push and hold the purple button until the door reaches the desired down position.  Preferably with an even seal along the bottom of the door.
• Push the remote control or smart panel which will set the down limit of the door and will begin to open the door.

Once the upper and lower limits have been set, we need to set the force adjustment.

• Push the purple button twice until the LED light starts flashing.
• Then push the door remote control to the down position.  That will set the closed force.
• Once again push the remote (open) button which will set the open force.
• Finally hit the (close) button on the remote control to close the door.

Check the LED indicator light to see if it has stopped flashing.  If so, the door limits and force adjustments have been set.

In this video we will set up the smart control panel time and temperature settings.

Dave walks us through the steps to set up the smart control panel.  In addition to this video it is advisable to refer to the Liftmaster 3800 Owner and Installation Manual.

Please remember to refer to your Owner’s Manual in addition to this video.

In this final video of the LIftmaster 3800 installation instrutional video series, Dave will install the radio controlled light assembly.

Since the light is operated by the remote control it turns on when you open the garage door which provides you with light on those dark cold winter nights.

The first step is to connect the provided template to the ceiling of the garage.  Then in the next step Dave connects the light assembly to the template.

Insert the light bulbs, attach the lens cover, and that’s it…you’re done!

We sincerely hope that this Liftmaster 3800 installation video series has been helpful.  It’s important to once again note that the best reference of instruction is the Liftmaster 3800 Owners Manual.

As always you’re most welcome to contact us with questions anytime.

Thanks,
Walt.
