Genie GS-1930 Scissor Lift Won’t Lift

If your Genie GS-1930 scissor lift will drive but the platform will not raise — or lowers unexpectedly — the issue is typically related to the lift hydraulic system, solenoid control, overload protection, or safety interlocks.

Lift failures are one of the most common GS-1930 service issues and are often resolved by inspecting a few key components.

Step 1: Confirm Battery Voltage

Even if the machine drives, low battery voltage can prevent the lift function from operating properly.

Check:

• Fully charged batteries

• Voltage under load

• Corroded battery cables

• Main breaker condition

If voltage drops significantly when attempting to lift, inspect the battery pack and cable assembly.

Step 2: Inspect the Solenoid Coils

The GS-1930 lift system relies on hydraulic solenoid coils mounted to the function manifold.

A failed coil may cause:

• No lift response

• Intermittent lift

• Clicking sound without movement

Common related parts include lift solenoid coils and valve components.

Step 3: Check the Function Manifold

The hydraulic function manifold controls lift flow and pressure.

Possible issues include:

• Sticking valve

• Internal contamination

• Failed relief valve

• Damaged seals

If the machine attempts to lift but stalls or moves slowly, inspect the manifold and hydraulic condition.

Step 4: Inspect the Pressure Transducer (Overload System)

The GS-1930 overload protection system uses a pressure transducer to monitor lift pressure.

If the transducer fails, the machine may:

• Refuse to lift

• Display overload condition

• Beep continuously

• Lift briefly then stop

Common related part:
1311101GT – Pressure Transducer (0–5K PSI)

Step 5: Verify Limit Switch & Pothole System Operation

Safety interlocks can disable lift if the machine detects an unsafe condition.

Inspect:

• Limit switches

• Roller arm assemblies

• Pothole actuator components

• Wiring harness connections

Faulty safety switches are a common cause of lift disablement.

Step 6: Check Hydraulic Filter & Oil Condition

Restricted hydraulic flow can prevent proper lift operation.

Inspect:

• Hydraulic filter element

• Oil level

• Oil contamination

• Signs of overheating

Common related part:
44788GT – Hydraulic Filter Element (10 Micron)
