For example:

• IS550/A may be compatible
• IS550/B is not compatible
• CM7600IC/A may be compatible
• CM7600IC/B is not compatible

The letter following the main model number is important. Do not order using only the first portion of the opener model.

Part-Number Matching

This board is intended to replace opener boards marked with numbers such as:

• 31184R
• 20386R
• 20386R.S

Additional manufacturing numbers may also appear on the original board. The presence of 31184R or 20386R should be confirmed along with the complete opener model number.

Do not order based only on the appearance of the circuit board. Genie manufactured several visually similar boards that are not interchangeable.

Common Symptoms of a Possible Failed Sequencer Board

A damaged sequencer board may cause symptoms such as:

• Opener does not respond to the wall control or remote
• Door opens but will not close
• No power reaches the Safe-T-Beam sensors
• Door reverses unexpectedly
• Opener light remains on
• Intermittent or unpredictable opener operation
• Learn or programming function does not respond
• Motor or relay does not activate

These symptoms can also be caused by damaged wiring, misaligned safety sensors, an incorrect force setting, a defective wall console, a faulty remote, door resistance, or another opener component.

Troubleshoot the complete system before replacing the circuit board.

Remote-Control Programming

The replacement board requires programming after installation. Existing remotes, wireless keypads, and HomeLink controls may need to be programmed again using the Learn Code or programming button on the replacement board.

Previously stored remote codes should not be expected to transfer automatically from the old board.

Package Contents

Remote controls, safety sensors, wall consoles, wiring, mounting hardware, and other garage door opener components are not included unless specifically stated.

Installation Notes

Disconnect electrical power from the garage door opener before removing the opener cover or touching internal electrical components.

Before disconnecting the original board:

1. Photograph all wire and connector locations.
2. Record the complete opener model and suffix.
3. Record all numbers printed on the original circuit board.
4. Inspect the wiring and connectors for heat or moisture damage.
5. Compare the replacement board with the original board.

Transfer the connectors carefully without pulling directly on the wires. Make sure each connector is fully seated before restoring power.

After installation, program the remotes and test the opener according to the manufacturer’s instructions.

Important Diagnostic Notes

A garage door that will not close is not automatically evidence of a failed sequencer board. First inspect the Safe-T-Beam sensors, sensor wiring, door balance, track alignment, wall-control wiring, and close-force setting.

If the door closes only while the wall-control button is continuously held, inspect the safety sensors and their wiring before replacing the circuit board.

Installed electrical parts may not be returnable. Verify compatibility and complete troubleshooting before installation.

Safety Warning

Garage door openers contain live electrical circuits and moving mechanical components. Disconnect power before servicing the opener.

After installing the replacement board, test:

• Open and close travel
• Force settings
• Safe-T-Beam sensors
• Contact-reversal function
• Wall control
• Remote controls
• Emergency release
• Opener lighting

Do not operate the garage door opener if the safety-reversal system or photoelectric sensors are not functioning correctly.
