Genie 35383R Excelerator Motor Drive Board – DC Screw Drive Opener Replacement

The Genie 35383R is a replacement motor drive circuit board for compatible Genie Excelerator DC screw-drive garage door openers manufactured in the applicable post-January 2007 configuration.

The motor drive board controls electrical power delivered to the opener motor and works together with the opener's main control board and motor assembly to operate the screw-drive system.

This is a model-specific electronic replacement part. Always verify the number on the original board and the exact opener model before ordering.

### What Is It Used For?

The 35383R is the electronic motor-drive board inside compatible Genie Excelerator powerheads.

Its job is to control electrical power supplied to the DC motor.

The system generally operates through:

Control Board → Motor Drive Board → DC Motor → Screw Drive → Carriage → Door

A malfunctioning motor drive board can prevent the motor from receiving or controlling power correctly.

### Possible Symptoms of a Failed Motor Drive Board

Depending on the opener and failure condition, symptoms may include:

- Opener has power but motor does not run
- Motor operates intermittently
- Door will not open or close
- Motor behaves erratically
- Visible damage or burned components on the board
- Correct power reaches the opener but the drive motor does not operate

These symptoms can also be caused by the main control board, motor, wiring, optical components, limits, or mechanical problems.

Proper diagnosis is strongly recommended before replacing an electronic board.

### Compatibility

The 35383R is associated with select Genie Excelerator DC screw-drive systems.

Genie Excelerator families include models such as:

- H8000 series
- ISD990
- ISD995
- ISD1000
- PRO99 series
- CMD9900

Compatibility varies by production date and internal board configuration.

For example, parts documentation specifically identifies 35383R as the drive PCB in select ISD990 / ISD990-2 configurations.

### Replacement Part Numbers

Supplier documentation lists 35383R as replacing select:

- 34463R
- 36428R.S

Do not assume every opener originally using one of these numbers can accept another board without checking the production version.

Compare the original board label and opener model before purchasing.

### Motor Drive Board vs. Main Control Board

The motor drive board is not the same component as the opener's main logic/control board.

On many Excelerator systems there are separate boards for:

- Motor drive / motor power control
- Main opener logic and control functions

If the opener has a logic, remote-control, limit, or programming problem, replacing the motor drive board may not correct the issue.

### Important Obsolescence Notice

Genie currently identifies the Excelerator motor drive board as an obsolete component in its current replacement-parts documentation.

Availability may therefore consist of remaining original inventory.

Because these boards are application-specific and older opener configurations vary, carefully verify compatibility before ordering.

### Package Contents

Includes:

- 1 – Genie 35383R Excelerator Motor Drive Board

Motor, main control board, powerhead, rail, wiring harnesses, optical components, and other opener parts are not included unless specifically stated.

### Important Installation & Electrical Safety

Disconnect the garage door opener from electrical power before opening the powerhead or replacing electronic components.

Electronic circuit boards can be damaged by static electricity, incorrect wiring, short circuits, or installation into an incompatible opener.

Before replacing the board:

- Verify the original board number
- Verify the opener model
- Inspect wiring and connectors
- Inspect the motor and related components
- Confirm that the garage door moves freely and is properly balanced

Installation and electrical diagnosis should be performed by a qualified garage door service technician when necessary.
