Garage door openers have evolved greatly over the years, but many homeowners still use or encounter models equipped with DIP switches—a small but powerful set of toggles that allow for secure, custom-coded communication between the opener unit and its remote. Among the most commonly used brands with this system is Craftsman.
If you’ve recently purchased an older Craftsman garage door opener or need to reprogram one, understanding how to program Craftsman garage door opener with DIP switches is a critical and valuable skill. This detailed, easy-to-read guide will walk you through every step of the process—from identifying your DIP switch system to syncing your remote with your opener.
Why DIP Switches Matter
Before diving into how to program them, it’s worth understanding what DIP switches do. “DIP” stands for Dual Inline Package, and these small switch blocks are used to configure electronic settings—like a digital lock.
Older garage door systems, particularly those from the 1980s to early 2000s, relied on DIP switches to match the signal between the remote transmitter and the garage door opener receiver. This allowed homeowners to set a secure code by manually flipping these tiny switches into unique patterns.
Though newer models now use rolling code technology, many Craftsman models—especially those labeled with 139.xxxxxx part numbers—still use this legacy system.

Tools You’ll Need
To program your Craftsman garage door opener with DIP switches, gather the following:
- A flathead precision screwdriver (for flipping DIP switches)
- Step ladder (to access the opener unit)
- Your Craftsman remote control (preferably with fresh batteries)
- A flashlight (for better visibility)
How To Program Craftsman Garage Door Opener With Dip Switches
Now let’s dive into the actual steps. This process assumes your Craftsman garage door opener uses a DIP switch system. If it does not, or if it uses a Learn button or rolling code system, this guide won’t apply.
Step 1: Locate the DIP Switches on the Opener Unit
- Climb a step ladder and find your garage door opener motor unit, typically located near the ceiling of your garage.
- Remove the light cover or control panel if necessary.
- Inside, locate the small rectangular bank of DIP switches. You’ll usually find 8 to 12 tiny switches, each labeled ON/OFF or 1/0.
Tip: Some units may label the switch positions as “Up” for ON and “Down” for OFF.
Step 2: Find and Access the DIP Switches on Your Remote
- Your Craftsman remote control will have a matching DIP switch bank.
- Slide open the battery compartment or use a screwdriver to open the back panel.
- Locate the DIP switches inside—these should match in number and layout to the ones on the opener unit.
Step 3: Match the DIP Switch Positions
Now, here’s the critical part: You must match the DIP switch positions exactly on both the opener and the remote. This forms a unique radio signal that the opener will recognize.
- Using a screwdriver or pen tip, flip each switch on the remote to mirror the position of the corresponding switch on the opener.
- Double-check your configuration to make sure there are no mismatches.
- Close the battery compartment on the remote and replace any panels you removed from the motor unit.
Step 4: Test the Programming
- Stand a few feet away from the garage door.
- Press the button on your remote.
- If the door begins to open or close, the DIP switches were successfully synced.
If the door doesn’t respond:
- Check your DIP switch alignment again.
- Ensure the remote battery is functioning.
- Make sure no switches were missed or set incorrectly.
Advanced Tips for Success
Even though programming via DIP switches is relatively straightforward, the following best practices will ensure optimal success:
1. Use Fresh Batteries
Weak or old batteries can lead to signal failures—even with perfect DIP switch settings.
2. Keep the Pattern Unique
If you’re in a neighborhood with older systems, avoid using a factory-default pattern. Choose a unique combination to prevent interference or security risks.
3. Sync Multiple Remotes
If you have more than one remote, repeat the same DIP switch settings across each remote so they all control the same garage door opener.
4. Note the Code
Take a picture or write down the switch configuration for future reference. This is especially useful if you ever lose your remote or need to sync a new one.
Common Issues & Troubleshooting
Let’s review a few common challenges users face when trying to program a Craftsman opener with DIP switches:
Remote Doesn’t Work After Syncing
- Battery is dead or installed incorrectly
- DIP switch configuration mismatch
- Garage door opener receiver is damaged
Door Opens Randomly or Doesn’t Close
- Interference from similar code nearby
- Cross-signal with another remote in neighborhood
- Consider changing your DIP switch pattern to something more unique.
FAQs: Understanding Your Craftsman Opener and DIP Switches
Q: How many DIP switch combinations are possible?
Most systems with 9 switches offer 512 combinations (2^9), and systems with 12 switches offer 4,096 combinations, offering a decent level of security.
Q: Are DIP switch systems outdated?
Yes, modern systems use rolling codes that change after each use, offering better security. However, DIP systems are still functional and widely used in older homes.
Q: Can I still get replacement remotes for my DIP switch Craftsman opener?
Absolutely. Brands like LiftMaster, Sears Craftsman, and Linear offer compatible remotes. Just make sure the frequency (usually 300 MHz or 390 MHz) matches your opener unit.
Upgrading from DIP Switch to Modern Tech
If you’re using a DIP switch system and are concerned about security or compatibility, you might want to upgrade your Craftsman opener to a newer model.
Benefits of upgrading include:
- Rolling code technology
- Wi-Fi and smartphone control
- Battery backup and smart features
Some users also install universal receivers that allow older openers to work with newer remotes.
Real-World Example
Let’s say you purchased a 1998 Craftsman 1/2 HP garage door opener with a model number 139.53985D. This unit uses a 12-DIP switch system.
You:
- Match the 12 DIP switches between the opener and your replacement remote.
- Program two additional remotes for family members using the same DIP switch pattern.
- Test operation—it works flawlessly.
Six months later, you replace the batteries and retain the code easily because you documented your pattern.
Safety Note: Never Share Your Code
Sharing photos of your DIP switch pattern online or with untrusted individuals can allow others to clone your remote. Always keep this pattern private.
Final Thoughts
Learning how to program Craftsman garage door opener with DIP switches might seem old-fashioned in an era of smart homes and voice assistants, but it’s still an incredibly practical skill.
