If your remote suddenly stops working or you’ve lost the original transmitter, figuring out the code system on a Genie Blue Max Code Type Garage Door Opener can be confusing. These older Genie systems use dip switch coding instead of modern rolling codes, which means programming works differently. This guide walks you through identifying your code type, setting it correctly, and troubleshooting common issues.
What Is a Genie Blue Max Code Type Garage Door Opener?
4
The Genie Blue Max garage door opener series was popular in the 1980s–1990s. Unlike modern openers that use rolling security codes, Blue Max units rely on fixed dip switch codes shared between the opener and the remote.
Key characteristics:
- 9 or 12 tiny dip switches
- Fixed radio frequency (typically 390 MHz)
- Manual code matching between remote and motor unit

How Do Dip Switch Codes Work?
Dip switches are tiny toggles inside both:
- The garage door opener motor housing
- The handheld remote control
Each switch can be set to ON, OFF, or sometimes CENTER. The pattern must match exactly for the remote to work.
Example 9-Switch Pattern
| Switch | Position |
|---|---|
| 1 | ON |
| 2 | OFF |
| 3 | ON |
| 4 | ON |
| 5 | OFF |
| 6 | OFF |
| 7 | ON |
| 8 | OFF |
| 9 | ON |
This creates thousands of possible combinations for basic security.
How to Find the Code on Your Genie Blue Max
Step-by-Step
- Unplug the opener for safety.
- Remove the light cover on the motor unit.
- Locate the dip switch bank on the receiver board.
- Write down the ON/OFF pattern.
- Open your remote battery cover.
- Match the dip switches to the same pattern.
Time required: 5–10 minutes.
How to Program a Genie Blue Max Remote
Unlike modern “learn button” systems, there is no programming button.
Programming Steps
- Open remote battery compartment.
- Use a pen tip to adjust dip switches.
- Match the exact pattern from the motor unit.
- Insert battery and test.
If matched correctly, the door should respond immediately.
What If Your Remote Has No Dip Switches?
Some replacement remotes are universal and require setting a code using a chart. You must:
- Identify the frequency (usually 390 MHz)
- Use the compatibility chart to set internal switches
Not all modern remotes support Blue Max systems.
Common Problems and Fixes
| Problem | Cause | Solution |
|---|---|---|
| Remote not working | Dip switch mismatch | Recheck pattern |
| Weak range | Low battery | Replace battery |
| Door opens randomly | Signal interference | Change dip pattern |
| No response | Faulty receiver | Inspect wiring |
| Works only nearby | Antenna issue | Extend antenna wire |
Can You Upgrade Security on Blue Max Openers?
Yes. Because dip switches use fixed codes, they are less secure than modern rolling code systems.
Upgrade options:
- Install a universal receiver with rolling code
- Replace opener with modern Genie unit
- Add keypad entry for convenience
How to Identify If You Have 9 or 12 Dip Switches
Open both the motor unit and remote. Count the switches:
- 9 switches = standard Blue Max format
- 12 switches = expanded code version (rare)
Both must match exactly.
Advantages vs Disadvantages of Dip Switch Systems
Advantages
- Simple to program
- No electronic syncing required
- Easy troubleshooting
Disadvantages
- Lower security
- Limited remote compatibility
- Aging components
When Should You Replace Instead of Repair?
Consider replacing if:
- Receiver board fails
- Remote replacements are hard to find
- You want smartphone control
- Security is a concern
Modern openers are quieter and safer.
