The LiftMaster 85870 is a robust, feature-rich residential garage door opener designed for heavy-duty doors and high-wind areas. With a 3/4 HP AC motor and a chain drive system, it combines power with smart home compatibility via Wi-Fi and Bluetooth. This guide outlines the preparation, installation, and setup of the LiftMaster 85870, with a focus on ensuring safe and efficient operation, as well as seamless integration with the myQ app and other smart home accessories.
Preparation
Before beginning the installation of the LiftMaster 85870, it is essential to gather all required tools and materials. The manufacturer’s official manual (Source 1) lists the following as necessary:
- A screwdriver set (both flathead and Phillips)
- A drill with appropriate bits
- A ladder
- A tape measure
- Safety gloves and goggles
Additionally, the manual recommends having the myQ serial number and product serial number written down for future reference. These can be found on the opener’s label and should be recorded in the manual’s preparation section.
The installation process must be carried out with attention to safety. The manual explicitly warns that the garage door will not close unless the Protector System is connected and properly aligned. This safety feature is crucial for preventing accidents and ensuring that the door functions correctly. Furthermore, the manual advises that the opener should not be installed on one-piece doors if unattended close features are to be used. Unattended close features should only be implemented with sectional doors.
Assembly
The assembly process for the LiftMaster 85870 involves several key steps, all detailed in the manufacturer’s manual (Source 1). The first step is to attach the rail to the head unit. The rail is designed to support the weight of the garage door and must be aligned properly to ensure smooth operation. The manual provides clear diagrams for aligning and securing the rail to the head unit using the included hardware.
Next, the door control is installed. The control panel is the user interface for the opener and must be mounted in a location that is easily accessible but out of the way of foot traffic. The manual specifies the use of mounting brackets and screws to secure the control panel to the wall or ceiling.
Following this, the chain drive system is assembled. The chain is attached to the trolley, and the tension is adjusted according to the instructions in the manual. Proper tension is essential for smooth and quiet operation. The chain should be adjusted so that it is taut but not overly tight, which could cause unnecessary wear on the motor and chain.
The installation of the safety sensors is another critical step. The LiftMaster 85870 includes safety sensors that detect obstructions and automatically reverse the door if anything is in the path. These sensors must be aligned correctly and tested to ensure they function as intended. The manual provides detailed instructions on how to install and test the sensors.
Finally, the mounting hardware is attached to the ceiling or wall. The manual specifies the use of heavy-duty brackets and anchors to ensure the opener is securely mounted and capable of supporting the weight of the garage door. Once the hardware is in place, the head unit is mounted and secured using the provided bolts and nuts.
Installation
The installation of the LiftMaster 85870 must be performed in accordance with local building codes and safety standards. The manufacturer’s manual (Source 1) provides detailed instructions for installing the opener, including the recommended height for the head unit and rail. The manual also includes information on the required clearance between the opener and the garage door to ensure proper operation.
One of the key considerations during installation is the positioning of the opener relative to the garage door. The opener must be installed at a height that allows the chain or belt to operate without interference. The manual recommends a minimum clearance of 18 inches between the opener and the door.
The installation of the myQ system is an important part of the process, as it enables smart home integration. The myQ system includes a Wi-Fi module that connects the opener to the user’s home network. The manual provides step-by-step instructions for connecting the myQ module to the opener and configuring it for use with the myQ app. This process involves setting up the Wi-Fi network and ensuring that the opener is properly registered.
Once the opener is installed, the manual recommends performing a series of tests to ensure that it is functioning correctly. These tests include opening and closing the door manually, testing the automatic close feature, and verifying that the safety sensors are working properly. The manual also includes instructions for adjusting the door’s travel limits and force settings to ensure smooth and safe operation.

The control panel must be installed in a location that is easily accessible but out of the way of foot traffic. The manual recommends a height of between 42 and 60 inches from the floor, depending on the user’s preference. Once the panel is installed, the manual provides instructions for connecting it to the opener and configuring its settings.
The control panel also includes a keyhole for a physical key, which allows the user to manually open and close the door in the event of a power outage or system failure. The manual provides instructions for programming the keyhole and setting up the key.
Install the Protector System
The Protector System is an essential component of the LiftMaster 85870 and must be installed and aligned properly to ensure safe operation. The system includes safety sensors that detect obstructions and automatically reverse the door if anything is in the path. The manual (Source 1) provides detailed instructions for installing and aligning the sensors.
The sensors must be mounted on either side of the garage door, with one sensor positioned near the floor and the other near the ceiling. The manual provides diagrams and instructions for aligning the sensors so that they are in direct line with each other. Once the sensors are installed, the manual recommends testing them to ensure that they are functioning properly.
The manual also includes instructions for adjusting the sensitivity of the sensors. The sensitivity setting determines how responsive the sensors are to obstructions. The manual recommends setting the sensitivity to a level that ensures the door will reverse if anything is in the path, while also avoiding unnecessary reversals due to minor obstructions.
Adjustments
After the LiftMaster 85870 is installed, it may be necessary to make adjustments to ensure that it operates smoothly and safely. The manual (Source 1) provides detailed instructions for adjusting the opener’s travel limits, force settings, and safety features.
The travel limits determine how far the door opens and closes. The manual recommends adjusting the travel limits to ensure that the door opens fully and closes completely without slamming. The manual provides instructions for adjusting the travel limits using the control panel.
The force settings determine how much force the opener applies when opening and closing the door. The manual recommends adjusting the force settings to ensure that the door opens and closes smoothly without excessive force. The manual provides instructions for adjusting the force settings using the control panel.
