What FAAx means on a GE range

The FAAx error code on a GE induction range indicates that the cooktop's pot detection system has failed to recognize a suitable cooking vessel on one of the induction zones. Induction cooktops use electromagnetic coils beneath the ceramic glass surface to detect the presence and size of ferromagnetic cookware. When the control board polls the coil and receives a signal that does not match the expected inductance profile for a properly sized, compatible pot or pan, it generates this fault. The "x" in the code designates which specific burner zone is affected.

The most common trigger for FAAx is simply placing a pot or pan that is too small for the selected zone, placing non-induction-compatible cookware (such as aluminum or copper without a magnetic base) on the burner, or centering the vessel off the coil. These are transient conditions that resolve immediately when the correct cookware is used. The control board continuously monitors coil feedback, so the error clears on its own once a properly sized, ferromagnetic vessel is detected.

A more serious hardware cause is a coil that has physically separated from the underside of the ceramic glass. Each induction coil must maintain close, consistent proximity to the glass surface to generate an accurate detection field. If mounting clips or adhesive have failed and the coil has dropped away, the detection signal will be too weak or inconsistent regardless of what cookware is placed on the surface. This condition requires physical inspection of the coil assembly from beneath the cooktop and cannot be resolved through cookware changes alone.

Common causes of FAAx

  1. 01

    Wrong pot size or off-center placement

    Wiring / connection

    The pot or pan is smaller than the minimum required for the selected induction zone, or it is not centered over the coil. Move the cookware to the center of the zone or switch to a larger pot.

  2. 02

    Non-induction-compatible cookware

    Wiring / connection

    Cookware made from aluminum, copper, glass, or ceramic without a magnetic base will not be detected by the induction coil. Test the pot with a magnet: if the magnet does not stick to the bottom, the cookware is incompatible.

  3. 03

    Induction coil separated from the glass

    Part replacement

    The coil assembly beneath the ceramic glass surface may have dropped away from its mounted position, weakening the detection field. This requires removing the cooktop to visually inspect the coil mounting hardware and reposition or resecure the coil.

  4. 04

    Failed induction coil

    Part replacement

    A damaged or burned-out induction coil will not produce the electromagnetic field needed for pot detection or heating. This requires component-level testing and coil replacement.

  5. 05

    Faulty control board

    Part replacement

    If the coil and cookware are both confirmed to be correct and properly positioned but the error persists, the control board may be misreading coil feedback. This is the least common cause and should be diagnosed after ruling out all other possibilities.

Frequently asked questions about FAAx

What does FAAx mean on a GE range?
FAAx is a pot detection fault on a GE induction range. It means the control board did not detect a suitable cooking vessel on one of the induction zones, identified by the number in place of "x". The error is triggered when cookware is too small, incompatible with induction, or when a hardware issue such as a dropped coil is present. Correcting the cookware is the first step to resolving it.
How do I fix the FAAx error on my GE induction range?
Start by placing a flat-bottomed, induction-compatible pot that is appropriately sized for the burner zone, centered over the element. If the error clears, the issue was with the cookware. If it persists with correct cookware, inspect the coil assembly beneath the glass for physical separation from the surface, and check for any visible damage to the coil itself.
Will resetting the range clear the FAAx error?
FAAx is a transient error, meaning it clears automatically once the cooktop detects a suitable pot. A power reset may temporarily clear the display, but if the underlying cause is incorrect cookware or a hardware problem such as a dropped coil, the error will return as soon as that zone is activated again.
Is it safe to keep using my GE range when the FAAx code is showing?
The affected induction zone will not heat while the FAAx error is active, so there is no burn or fire risk from that burner. The rest of the range should continue to function normally. However, if the coil has physically separated from the glass, continued use of that zone could cause further damage and the cooktop should not be operated until the coil is resecured.
How much does it cost to repair a GE range showing FAAx?
If the fix is simply switching to the correct cookware, there is no repair cost. If the induction coil has dropped and needs to be remounted or replaced, parts and labor can range from $150 to $400 depending on the specific model and coil assembly. A control board replacement, if needed, typically ranges from $200 to $500 including labor.
