GE codesGE range codes

Problem within timekeeping circuits due to fluctuation of the 50 Hz power supply, or stuck function switch/button (bake, broil, clean etc.) on ERC.

First step from the service manual

Reset time and/or cooking operation if applicable. Test operation of buttons to ensure they move freely. If problem cannot be found, remove lens from ERC and determine if problem is in button section of lens or in ERC.

What F6 means on a GE range

The F6 error code on a GE range indicates a problem with the timekeeping circuit, specifically related to the 60 Hz frequency signal the control board uses to track time. The range's clock circuit monitors the AC power line frequency as its timing reference. When the control board detects an interruption or momentary change in that 60 Hz signal, it logs F6 and alerts the user. This can occur because of a brief power grid fluctuation, a voltage spike, or an issue with the control board's internal timekeeping components.

For homeowners, this means the range's electronic clock lost its timing reference, even if only for a split second. Think of it like a power blip that knocked the clock off sync. The range detected this irregularity and flagged it rather than continuing to operate on potentially incorrect time-based functions. In many cases, the issue is external to the range itself, originating from the power supply rather than a failed part.

Because momentary frequency changes are often the trigger, a simple reset clears the code in a large percentage of cases. If the code returns repeatedly without any obvious power disruptions, the control board's timekeeping circuit may have a hardware fault that requires board replacement.

Common causes of F6

  1. 01

    Momentary power grid frequency fluctuation

    Wiring / connection

    A brief dip or spike in the AC line frequency from the utility grid can cause the timekeeping circuit to lose its 60 Hz reference and trigger F6. This is the most common cause and usually requires no repair.

  2. 02

    Voltage spike or power surge at the outlet

    Wiring / connection

    A surge event, such as one caused by a nearby lightning strike or a large appliance cycling on the same circuit, can disrupt the frequency signal the control board monitors. A surge protector or dedicated circuit can help prevent recurrence.

  3. 03

    Faulty main control board timekeeping circuit

    Part replacement

    If the internal oscillator or timekeeping components on the control board have failed, the board will repeatedly misread or lose the 60 Hz reference and generate F6 even during stable power conditions. Replacing the control board is required.

  4. 04

    Loose or degraded power supply wiring to the control board

    Part replacement

    A loose neutral connection or deteriorated wiring between the terminal block and the control board can cause irregular voltage and frequency signals at the board's input, triggering F6 intermittently.

Frequently asked questions about F6

What does the F6 error code mean on a GE range?
F6 on a GE range means the control board detected a problem with its timekeeping circuit, typically caused by a momentary change in the 60 Hz AC line frequency it uses as a timing reference. This can happen due to a brief power fluctuation from the utility grid or a surge on the circuit. The range flags the event rather than continuing to operate on a potentially inaccurate time base.
How do I fix the F6 error code on my GE range?
Start by resetting the range: turn off the circuit breaker for 60 seconds, then restore power. If F6 clears and does not return, the cause was likely a temporary power fluctuation and no repair is needed. If F6 comes back repeatedly under normal conditions, check the wiring connections at the terminal block and control board. A persistently returning F6 that does not respond to resets points to a failing control board that will need replacement.
Is it safe to keep using my GE range while it shows the F6 code?
In most cases, yes, but with caution. The F6 code relates to the timekeeping circuit, not the heating elements or gas valves, so basic cooking functions typically still work. However, any timed cooking functions, delay start, or clock-dependent operations may not work correctly until the issue is resolved. If the code is recurring frequently, have the range inspected before relying on timed features.
How much does it cost to fix the F6 error on a GE range?
If the cause is a power fluctuation, the fix is free since a reset resolves it. If the control board needs replacement, expect to pay $150 to $350 for the part depending on the model, plus $100 to $200 in labor if you hire a technician. DIY board replacement is feasible for someone comfortable with appliance repair, as it typically involves unplugging connectors and swapping the board, though you should confirm the exact model number before ordering parts.
Why does the F6 code keep coming back on my GE range after I reset it?
A recurring F6 after repeated resets suggests the issue is not an external power fluctuation but rather an internal fault in the control board's timekeeping circuit or a wiring problem between the terminal block and the board. Check that all wiring connections at the control board and terminal block are tight and show no signs of burning or corrosion. If connections are secure and the code continues to return, the control board likely needs replacement.
