Genie ACSCTG Type 3 Garage Door Opener Remote — What Is It?

How to Confirm Compatibility
Check these three items before pairing or buying a replacement:
- Your opener has a Learn/Program button (not DIP switches)
- The antenna wire hangs from the motor unit
- Your opener is Genie Intellicode (most units after the late 1990s)
If all three are true, this remote is compatible.
Step-by-Step: Pairing the ACSCTG Type 3 Remote
⏱ Time required: 2 minutes
- Locate the Learn/Program button on the opener motor
- Press and release it (LED starts blinking)
- Within 30 seconds, press the remote button once
- LED stops blinking = pairing complete
- Test the door
Tip: Stand 3–6 feet from the opener during pairing.
If Pairing Fails: Do This First
Most failures are caused by old memory or battery issues.
Reset the Opener Memory
- Hold the Learn button for 10 seconds
- LED turns off → memory cleared
- Re-pair only the remotes you use
Battery Replacement for ACSCTG Type 3
This remote uses a CR2032 coin battery.
Steps:
- Open back cover with a coin
- Replace battery (+ side up)
- Close cover firmly
- Test before re-pairing
Battery cost: $3–$6
A weak battery is the #1 reason for short range or no response.
Signs the Remote Needs Replacement (Not Repair)
| Symptom | Likely Cause | Fix |
|---|---|---|
| LED very dim | Battery/aging board | Replace battery/remote |
| Works only up close | Antenna or failing remote | Replace |
| Buttons unresponsive | Internal wear | Replace |
| Intermittent signal | Aging electronics | Replace |
Because this is an older model, replacement is often easier.
Best Replacement Remotes That Work the Same
| Replacement Model | Buttons | Works With Intellicode | Price |
|---|---|---|---|
| Genie G3T-R | 3 | Yes | $20–$35 |
| Genie GM3T-R | 3 | Yes | $25–$40 |
| Universal GK-R | 4 | Yes | $18–$30 |
These are modern versions of the same technology.
Remote Range and Performance Expectations
A healthy ACSCTG Type 3 should work from:
- 50–100 feet distance
- Through a closed garage door
- Without needing to aim precisely
If not, check the opener’s antenna wire is hanging straight down.
Common Troubleshooting Checklist
- Replace CR2032 battery
- Reset opener memory
- Re-pair remote slowly
- Check antenna wire position
- Confirm Intellicode compatibility
These steps solve over 90% of problems.
Can You Use a Universal Remote?
Yes — but it must support:
- Genie Intellicode
- 315/390 MHz
- Rolling code pairing
Universal remotes are helpful if you manage multiple garage brands.
Adding a Keypad or Wall Console as Backup
Many users add:
| Device | Benefit |
|---|---|
| Wireless keypad | Entry without remote |
| Wall console | Reliable indoor control |
| Extra remote | Backup for vehicles |
These reduce dependence on one aging remote.
