What LOC means on a GE range

The LOC error code on a GE range relates to a failure in the gas lockout valve positioning switch system. This safety system uses a motorized lockout valve to physically block gas flow to the cooktop burners when the control lock feature is engaged. A positioning switch provides feedback to the control board about the valve's current position. When the control board loses that feedback signal, it cannot confirm whether the valve is open or closed, triggering the LOC code. A flashing LOC display indicates the control board has lost valve position feedback and the lockout motor is running continuously trying to find a valid position. A steady LOC display means the cooktop is actively locked out.

The positioning switch assembly uses two contact pairs to communicate valve position: a Yellow-to-Orange contact set and a Yellow-to-Silver contact set. These contacts close or open at specific points in the valve's travel, signaling to the control board where the valve is in its rotation. If either contact pair fails to open or close at the correct position, or if the wiring between the switches and the control board is damaged, the motor will continue running as the system searches for confirmation of valve placement.

Common causes include worn or burned switch contacts, a stalled or failed lockout motor, broken wiring in the harness connecting the switches to the control board, or a mechanically jammed valve that prevents the motor from completing its travel. Diagnosing the issue starts with testing the Yellow-to-Orange and Yellow-to-Silver contact pairs directly for continuity at rest and through valve rotation, which helps isolate whether the problem is electrical or mechanical in nature.

Common causes of LOC

  1. 01

    Failed lockout valve positioning switch contacts

    Part replacement

    The Yellow-to-Orange or Yellow-to-Silver contact pairs inside the positioning switch assembly can wear out or develop poor contact, preventing the control board from receiving accurate valve position feedback. Test each contact pair for continuity through the full range of valve travel to identify which set has failed.

  2. 02

    Damaged or broken wiring harness

    Wiring / connection

    The wires connecting the positioning switches to the control board can crack, fray, or lose continuity, especially near connector terminals. Inspect the harness for visible damage and check for continuity at each wire with a multimeter.

  3. 03

    Stalled or burned-out lockout motor

    Part replacement

    If the lockout motor cannot complete its travel due to mechanical wear or burnout, it will run continuously without ever reaching a valid switch position. Listen for unusual humming or no motor movement at all when the error is active.

  4. 04

    Mechanically jammed lockout valve

    Part replacement

    Debris, corrosion, or a mechanical obstruction in the valve body can prevent the motor from rotating the valve to the correct position, which in turn prevents the positioning switches from confirming valve state.

  5. 05

    Faulty control board

    Part replacement

    If the switch contacts and wiring test correctly but the LOC error persists, the control board itself may have failed and is not properly reading the feedback signals from the positioning switches.

Frequently asked questions about LOC

What does LOC mean on a GE range?
LOC on a GE range indicates a problem with the gas lockout valve positioning switch system. A flashing LOC means the control board has lost position feedback from the valve and the lockout motor is running continuously. A steady LOC means the cooktop is actively locked out. The issue involves the Yellow-to-Orange and Yellow-to-Silver positioning switch contacts that report valve position to the control board.
Can I fix the LOC error on my GE range myself?
A knowledgeable DIYer can start by inspecting the wiring harness connected to the lockout valve positioning switches for obvious damage and testing the contact pairs with a multimeter. However, replacing the lockout valve assembly or the control board involves working near gas components, which carries risk if not done carefully. If you are not confident working around gas systems, having a qualified technician complete the repair is the safer choice.
Is it safe to use my GE range when LOC is displayed?
A steady LOC display means the cooktop burners are locked out and gas flow is blocked, so using the cooktop is not possible in that state. A flashing LOC means the motor is running continuously, which is an abnormal condition and the range should not be used until the fault is resolved. In either case, do not attempt to bypass the lockout system, as it is a safety feature designed to control gas flow.
Will resetting my GE range clear the LOC error code?
Cycling power to the range by unplugging it or tripping the circuit breaker for about 30 seconds may temporarily clear the display, but if the underlying positioning switch or motor fault still exists, the LOC error will return once power is restored and the system attempts to verify valve position. A reset alone does not fix the root cause.
How much does it cost to repair a GE range LOC error?
Repair costs depend on which component has failed. A wiring harness repair is typically on the lower end, often in the range of $75 to $200 including labor. Replacing the lockout valve assembly or motor can run from $150 to $400 depending on parts pricing and labor rates in your area. A control board replacement tends to be the most expensive option, often ranging from $200 to $500 or more. Getting a diagnosis first helps avoid replacing parts unnecessarily.
