Introduction
The Genie GS-1930 is a compact, battery-powered scissor lift designed for indoor use on smooth surfaces. A common issue faced by operators is the appearance of Fault Code 18, accompanied by a warning beep, indicating a problem with the pothole guard system. Understanding the causes and solutions for this error is essential for maintaining the lift's performance and safety.
Understanding Fault Code 18
Fault Code 18 on the Genie GS-1930 signifies a malfunction in the pothole guard system. The pothole guard is a safety feature that automatically deploys when the lift is lowered to prevent the platform from dropping into a pothole or uneven surface. If the system detects an issue with the pothole guard, such as a faulty switch or obstruction, it will trigger Code 18 to alert the operator .
Common Causes of Code 18
Several factors can trigger Fault Code 18:
To resolve Fault Code 18, follow these steps:
In some cases, the issue may lie with the 5-pole relay located in the hydraulic compartment. If this relay is overheating or malfunctioning, it can cause the pothole guard system to fail. Monitoring the relay's temperature and replacing it if necessary can help resolve the issue .
Conclusion
Fault Code 18 on the Genie GS-1930 indicates a problem with the pothole guard system, which is crucial for the lift's safety. By systematically troubleshooting the limit switches, wiring, relays, and mechanical components, operators can identify and resolve the issue, ensuring the lift operates safely and efficiently.

Common Causes of Code 18
Several factors can trigger Fault Code 18:
- Faulty Limit Switches: The limit switches monitor the position of the pothole guard. If these switches are malfunctioning or have poor connections, they may not accurately detect the guard's status.
- Obstructions in the Pothole Guard Linkage: Debris or damage in the pothole guard mechanism can prevent proper deployment, leading to the fault code.
- Electrical Issues: Loose or corroded wiring connections, especially near the pothole guard switches, can disrupt the system's function .
- Relay or Fuse Problems: A malfunctioning relay or blown fuse supplying power to the pothole guard system can cause it to fail.
To resolve Fault Code 18, follow these steps:
- Inspect Limit Switches: Manually activate each limit switch to ensure they click and function correctly.
- Check for Obstructions: Examine the pothole guard mechanism for any debris or damage that could impede movement.
- Examine Wiring Connections: Look for loose, damaged, or corroded wires near the pothole guard switches and repair as necessary.
- Test Relays and Fuses: Verify that the relay and fuse supplying power to the pothole guard system are functioning correctly.
- Bypass the System Temporarily: If the issue is intermittent, consider bypassing the pothole guard system to determine if it resolves the problem.
In some cases, the issue may lie with the 5-pole relay located in the hydraulic compartment. If this relay is overheating or malfunctioning, it can cause the pothole guard system to fail. Monitoring the relay's temperature and replacing it if necessary can help resolve the issue .
