Genie is one of the most trusted names in residential garage door openers, known for innovation, reliability, and safety. Whether you’re upgrading an existing unit, replacing worn components, or troubleshooting a malfunction, understanding the various Genie parts is essential. From remote controls and keypads to motor units, rail systems, and safety sensors, each component plays a vital role in the system’s smooth operation. This guide covers all major Genie garage door opener parts—what they do, compatible models, and part numbers—to help homeowners and technicians find exactly what they need.
Remote Controls
Genie remotes (wireless transmitters) use Intellicode® rolling-code security. They come in one-, two-, or three-button versions for controlling up to 1–3 Genie openers. For example, the G1T-BX 1-button remote and G3T-R 3-button remote use Auto-Seek Dual-Frequency (315/390 MHz) for reliable operation. These remotes automatically change their access code on every use to prevent unauthorized entry.
They include a built-in battery (CR2032) and often a visor clip or keyring slot. Genie’s remotes are generally backward-compatible with Intellicode-equipped openers: e.g. the G3T-R works with all Genie units made since ~1997 (up to three doors) and two-door functionality on 1995–97 models. Compatible part numbers include G1T (1-button), G2T (2-button), G3T (3-button), etc. Genie’s replacement remotes are sold individually or in multi-packs, and include programming instructions. (See the Genie parts store “Remotes” section.)
Wall Consoles & Keypads
Genie wall consoles are the wired in-garage control panel. The standard Series II console (e.g. model 39165R) has three buttons for Open/Close, Light, and Vacation Lock, with a backlit panel and LED indicators. It was included with most Genie Intellicode openers since 1995 and works on all Series II-equipped models. (Genie briefly used a Series III console (model 37222R) on some 2010–2012 units; those units require the specific Series III board or universal kit.)
Newer wireless wall consoles (Genie part 39902R) mount without wiring anywhere in the garage; they are battery-powered and compatible with all Intellicode openers made since 2013. These wireless units feature large buttons, a blue locating LED, and a built-in door closing “delay” button (10–30 sec) as well as a work-light on/off button. Genie also offers Universal wireless consoles (GUWWC-R) and basic push-buttons for older models. Outside keypads (e.g. model 37142A or GKS-315) are also available to enter a PIN code from outside. All consoles and keypads must be programmed to the opener; Genie provides compatibility charts on its website.
Safety Sensors (Safe-T-Beams)
All Genie openers use photoelectric safety sensors (“Safe-T-Beams”) installed near the floor on either side of the garage door. A transmitter (green LED) and a receiver (red LED) send an invisible infrared beam across the door opening. If the beam is interrupted (e.g. by a child or object), the opener automatically reverses the door to prevent injury.
Genie replacement sensor kits (model GSTB-R, part 37334R/37220R) include both emitter and receiver, mounting brackets, and wires. They are compatible with all Genie Intellicode residential openers that require sensors (all modern models since 1995). (Genie units built before 1993 may not have required sensors.) The sensors must be properly aligned and wired (using 18/2 bell wire) for correct operation. Extensions and universal brackets are sold for different mounting needs. Note: Replace both sensors together and test the beam alignment after any repair.
Motor Unit (Powerhead)
The motor unit (powerhead) is the main overhead enclosure that houses the motor, gearbox, light, and logic board. Genie chain- and belt-drive models use a 140 V DC permanent-magnet motor (rated from ½ HP to 1¼ HPc) for smooth, quiet lifting. Wall-mount models (like the 2020/3120 or wall-screw units) use a lower-voltage 24 V DC motor. These motors drive either a chain, belt or screw-travel mechanism. Inside the housing is also the integrated light assembly (incandescent or LED lamp socket) and the logic board.
For example, part 38644R.S is a common Genie DC Motor Assembly replacement (with mounting screws included). Replacement motors/gearboxes come as complete assemblies for specific models (see Genie part catalog). The motor’s output is typically attached via a coupler to a drive shaft. When replacing the motor or cover, always disconnect power and relieve door tension as per the manual.
Circuit Boards & Electronics
Inside each Genie opener’s powerhead is a circuit board (logic board) that controls all electronics and safety features. Modern Genies use Intellicode® security on these boards. For most current models, the board is a Series II electronics board (e.g. part 39048R.S) which handles inputs from remotes, wall console, sensors, and controls the motor and lights. Older 2010–2012 “Series III” models used a different board; a Genie kit (39057R.S) converts Series III units to the newer board and provides a Series II console.
Genie boards must be programmed to the opener and may require reprogramming if replaced. Common board components include the wireless receiver, motion encoder inputs, infrared sensor connectors, and relay outputs for the door and light. Replacement boards are sold by model number (see Genie’s parts site).
Drive Belts and Chains
Genie offers chain-drive and belt-drive systems. Chain-drive openers use a roller chain (steel links) to move the trolley along the rail; chains are strong but slightly noisier. Belt-drive models use a continuous steel-reinforced rubber belt (toothed) for very quiet operation. For example, replacement belts for Genie belt drives include part 37561R.S (7′ doors) or 37561S.S (8′ doors). In either system, a carriage (trolley) attaches to the chain or belt via a clevis/turnbuckle and pulls the door. Genie also has screw-drive units (rare) which use a long threaded steel rod inside a tubular rail; a nut on the motor drives this rod. Drive belts/chains wear over time and should be replaced if frayed or stretched – replacements are sold as complete assemblies (chain or belt plus leader arm).
Trolley (Carriage) Assembly
【32†】The trolley (carriage) assembly is the moving block that runs along the rail and actually pushes/pulls the door arm. On belt- and chain-drive models, part number 38893R.S is the standard carriage assembly. It “runs up and down the rail, attaching to the turnbuckle on the chain or belt to open and close the garage door”. (The chain/belt’s end is threaded into the turnbuckle, which is fastened to the carriage.) The carriage contains a gear block and rollers compatible with the rail. If a trolley is broken or jammed, the entire carriage assembly is replaced. Genie carriages include the internal hardware and mounting holes for the chain/belt connect. Note: Curved or straight door arms (see below) attach to this carriage via a pin or clip.
Rail Systems
Genie rails come in various styles: C-channel rails (single-piece steel channel) for lighter or screw-drive units, and T-style rails (tube or T-section) for more heavy-duty chain/belt drives. Rails are often sold in sections (standard 5-piece kits for an 8-foot door). For example, part 38244R.S is a one-piece C-channel rail for screw-drive openers. Belt-drive openers use C-channel rails (part 38246R.S) or tubular sections (part 39411R.S kit for 8′). Chain-drive Opener rails include one-piece (38245R.S C-channel) or 5-piece kits (39410R.S for 8′ doors). The rail provides the track for the trolley, and has mount points for ceiling brackets and end supports. Rail support brackets (Genie 36728A.S) and head brackets (39173R, 36987A.S with belt guard) hold the rail and opener together at the garage ceiling. Rails must be assembled and aligned per the manual; Genie sells replacement rail sections for all standard models.
Springs and Hardware
Garage door springs (torsion or extension springs) are not part of the Genie opener itself but rather part of the door’s hardware. They are mounted on the door/header and do the heavy lifting; the opener merely drives the door arm. Genie openers do use small springs in their assemblies (e.g. a release-cable spring clip or chain tension spring in some models), but major springs for counterbalance are on the door. Genie provides header brackets (35421A.S) that bolt to the wall above the door and anchor the rail.
It also supplies various rail brackets (36728A.S and 36987A.S) to connect rail sections and a belt guard. The Mounting Flange (38123A.S) and Coupler (36645R.S) join the motor to the rail drive. A Bearing Block (37844R.S) supports the end of a C-channel rail. Genie also offers Capacitors and Pulleys as part of the motor/drive hardware. Genuine Genie header brackets and door brackets (curved 37476A.S and straight 37475A.S arms) attach the opener’s trolley to the door. All these brackets and arms are matched to Genie models and should be installed per instructions.
Light Lenses and Covers【69†】
Genie openers include an interior lamp (usually 100W incandescent or LED bulb) that illuminates the garage. The plastic light lens cover (part 38245A.S, sold individually) snaps over the lamp socket in the powerhead to diffuse the light. These covers are clear or frosted and replace brittle or broken lens panels. Some models also have indicator LEDs on the console or opener housing (e.g. Genies with HomeLink code the LED). Replacement light bulbs (incandescent or LED) are also sold under accessories, but these are standard 4″ bayonet-base bulbs unless otherwise specified.
Battery Backup
Many Genie openers (especially Smart/Aladdin-equipped models) offer optional battery backup kits so the door will operate during power outages. For 140 V DC openers (chain/belt drive), Genie’s backup unit (part 41590R) contains a sealed 12V battery pack. When AC power fails, the system automatically switches to battery and can cycle the door up to ~50 times. Genies with 24 V motors (smaller lifts or wall-mount units) use different backup kits (e.g. 39524R for models 3020H/3120H).
The battery pack mounts in a box on the opener or ceiling, with a cable to the opener. Genie’s literature notes that “when the power goes out, the opener’s battery power kicks into gear automatically. Never be locked out of your garage again”. The kits include the battery, wiring harness, and mounting hardware; replacement batteries (e.g. 111658.0002.S, a 12 V battery) are sold when the battery ages. (Note: California law requires backup on new openers installed since 2019.)
