A Craftsman garage door opener pad blinking is typically a sign that there is a problem with the keypad or the system’s communication between devices.

Why is Your Craftsman Garage Door Opener Pad Blinking?
Before jumping into solutions, it’s important to understand the reasons behind a blinking Craftsman garage door opener keypad. There are several causes that could lead to this issue. Some of the most common ones include:
1. Dead or Low Batteries
One of the most common reasons for a blinking Craftsman garage door opener pad is low or dead batteries. When the batteries in your keypad are running low, it may cause the pad to blink continuously. This indicates that the device is unable to operate properly due to insufficient power.

4. Miscommunication Between the Keypad and Opener
The blinking pad can also be a sign of a communication problem between the garage door opener and the keypad. This could be caused by a signal failure, interference from other devices, or a problem with the opener’s receiver.
5. Electrical Interference
Sometimes, external electrical interference can affect the functioning of the keypad and cause it to blink. Devices like microwaves, routers, or other wireless equipment can disrupt the signal transmission between the keypad and the opener, leading to an error or blinking light.
Understanding these possible causes will help you troubleshoot your Craftsman garage door opener pad blinking more effectively.
How to Fix a Craftsman Garage Door Opener Pad Blinking
If your Craftsman garage door opener pad is blinking, don’t worry! There are several troubleshooting steps you can take to fix the problem. Let’s walk through each solution:
Step 1: Check and Replace the Batteries
The most straightforward solution for a blinking keypad is to check and replace the batteries. A blinking light typically indicates low or dead batteries, and replacing them may fix the issue.
How to Replace the Batteries:
- Locate the Battery Compartment: Most Craftsman garage door keypads have a small compartment on the back of the unit where the batteries are stored. You may need a screwdriver to open the compartment.
- Remove the Old Batteries: Once you open the compartment, remove the old batteries. Take note of the orientation (positive and negative sides) of the batteries before removing them so you can install the new ones correctly.
- Insert New Batteries: Insert fresh, high-quality batteries. Alkaline batteries are typically recommended for optimal performance.
- Test the Keypad: After replacing the batteries, close the compartment and test the keypad. If the blinking stops, then you’ve resolved the issue.
If replacing the batteries doesn’t stop the blinking, move on to the next troubleshooting steps.
Step 2: Reprogram the Keypad
If the keypad is still blinking after replacing the batteries, it might have lost its programming. You can easily reprogram your Craftsman keypad using the following steps.
How to Reprogram the Keypad:
- Locate the Learn Button on the Opener: First, you need to locate the “Learn” button on the garage door opener. This button is typically found on the back of the opener’s motor unit.
- Press the Learn Button: Press and release the Learn button on the opener. After doing so, the indicator light next to the button will start blinking, signaling that the opener is in programming mode.
- Enter the Code on the Keypad: Within 30 seconds of pressing the Learn button, go to your keypad and enter the 4-digit code you wish to use. Once entered, press the “Enter” button.
- Wait for Confirmation: The LED light on the opener should stop blinking and remain solid. This confirms that the keypad has been successfully reprogrammed.
After reprogramming, test the keypad to see if the blinking has stopped. If the issue persists, move on to the next troubleshooting steps.
Step 3: Clear the Keypad Memory
If reprogramming the keypad didn’t fix the blinking light, you may need to clear the keypad’s memory. Clearing the memory will remove any stored codes and reset the system.
How to Clear the Keypad Memory:
- Locate the Program Button: On the keypad, find the “Program” or “Reset” button.
- Press and Hold the Button: Press and hold the Program or Reset button for about 10 seconds until the light on the keypad turns off.
- Reprogram the Keypad: After clearing the memory, reprogram the keypad using the steps outlined earlier.
Step 4: Check for Electrical Interference
Electrical interference from other devices could be affecting the signal between the keypad and the opener, causing the keypad to blink. This issue can be solved by moving the keypad or opener away from potential sources of interference.
How to Reduce Electrical Interference:
- Move Electronics Away: If you have other electronics nearby, such as routers, microwaves, or wireless devices, try moving them farther away from the keypad and opener.
- Check the Antenna: Ensure that the antenna on the opener is properly positioned and not obstructed by any objects. A blocked antenna can lead to signal issues.
Step 5: Inspect the Wiring and Connections
Sometimes, faulty wiring or loose connections can cause communication issues between the keypad and the opener, resulting in a blinking light. Inspect the wiring of the opener and the keypad for any visible damage.
How to Inspect the Wiring:
- Turn Off Power: Before inspecting any wires, turn off the power to the garage door opener.
- Check for Loose Wires: Look for any loose or damaged wires in the opener unit and keypad. Tighten any loose connections or replace damaged wires as needed.
Step 6: Reset the Garage Door Opener
If all else fails, you may need to reset the entire garage door opener system. This can help fix any deeper issues with the system’s electronics.
How to Reset the Opener:
- Unplug the Opener: Disconnect the garage door opener from its power source by unplugging it.
- Wait for 5-10 Minutes: Leave the opener unplugged for a few minutes to reset its internal electronics.
- Reconnect and Reprogram: After the reset, plug the opener back in and reprogram the keypad following the steps mentioned above.
