LiftMaster 4690L vs 87802 vs 85870: Full Comparison

As garage door opener technology evolves, LiftMaster continues to set the standard for performance, reliability, and safety. The new LiftMaster 4690L represents the next step in that evolution—replacing older models like the 87802 and 85870 with a smarter, more connected design built for everyday use.

If you’re considering an upgrade or looking to understand how the new system compares, this guide breaks down the key differences and what they mean for your home or workspace.

Overview: What Each Model Offers

LiftMaster 4690L: The Smart Upgrade

The 4690L replaces older chain-drive openers with a more refined, connected system. Its DC motor provides smoother operation and lower noise than traditional AC or heavy-duty drives.

Built-in Corner-to-Corner Lighting™ brightens the entire garage with 360° motion-activated coverage, while the integrated camera connects through the myQ® app so you can monitor activity in real time.

Key advantages:

• 1080p camera with adjustable angle and live streaming.

• Battery backup included standard.

• Quieter, smoother DC chain drive.

• Modern LED lighting system for full visibility.

• Smart control and remote monitoring through myQ®.

LiftMaster 87802: Power and Performance for Heavy Doors 

The 87802 was designed for strength and reliability. It uses a heavy-duty DC chain drive and a reinforced I-beam rail system to lift heavier or reinforced garage doors, especially in high-wind regions. With 2000-lumen Corner-to-Corner Lighting™ and Battery Backup, it remains a solid choice for larger installations.

Where it still stands out:

• Great for heavy or insulated doors.

• 2000-lumen LED system for bright coverage.

• myQ diagnostics and remote control via smartphone.

• Built-in Battery Backup for power outages.

What’s missing:

• No built-in camera.

• Louder operation than DC belt or premium systems.

LiftMaster 85870: Reliable Strength with Traditional Design

The 85870 is a classic, powerful ¾ HP AC chain-drive opener built for durability.
It remains one of LiftMaster’s strongest models, well-suited for large residential or commercial doors that require high torque.

Highlights:

• AC motor and chain drive built for long-term use.

• Motion-detection lighting for added visibility.

• myQ connectivity for control from your phone.

• Compatible with optional Automatic Garage Door Lock (841LM) for extra security.

Trade-offs:

• No battery backup.

• No camera or modern LED upgrades.

• Louder operation due to AC motor and chain system.

What’s New in the 4690L

Compared to both the 87802 and 85870, the 4690L introduces several key improvements:

1. Built-In Camera: Monitor your garage in real time without extra add-ons.

2. Smarter Lighting: The 360° LED system delivers even brightness throughout the garage.

3. Quieter Motor: The DC chain drive runs smoother and produces less vibration.

4. Battery Backup Included: Always operational, even in power outages.

5. Smarter App Control: myQ integration now includes access sharing, camera viewing, and service diagnostics in one app.
