What FAA means on a GE cooktop

The FAA error code on a GE induction cooktop indicates that the control board has received a bad or out-of-range reading from the coil thermistor. The coil thermistor is a temperature-sensing component mounted in or near the induction coil assembly within the induction tray. Its primary function is to monitor the operating temperature of the induction coil and report that data to the main control board. When the thermistor sends a signal that falls outside the expected resistance or voltage parameters, the board interprets this as a fault and halts operation to prevent potential overheating or coil damage.

The induction tray is the assembly that houses the induction coil and associated components beneath the ceramic glass surface. The thermistor is typically integrated into or positioned directly against this tray assembly. A faulty reading can result from a thermistor that has drifted out of spec, developed an open or short circuit, or from a physical problem with the induction tray itself, such as damage or improper seating that affects thermistor contact. Wiring harness issues between the thermistor and the control board can also produce a bad reading.

The recommended first diagnostic step is to inspect the coil thermistor and the induction tray for visible damage, loose connectors, or signs of overheating. If the thermistor checks out of spec or the tray shows damage, the guidance is to replace the coil assembly. Because the thermistor is typically integrated with the coil unit on these cooktops, replacement often means replacing the entire coil rather than the thermistor alone.

Common causes of FAA

  1. 01

    Faulty coil thermistor

    Part replacement

    The thermistor itself may have failed, producing a resistance value outside the acceptable range. This is the most likely cause and typically requires replacing the coil assembly since the thermistor is integrated into it.

  2. 02

    Damaged or improperly seated induction tray

    Part replacement

    Physical damage to the induction tray or improper seating can disrupt thermistor contact or affect the sensor's readings. Inspect the tray for cracks, burn marks, or signs that it has shifted out of position.

  3. 03

    Loose or damaged wiring harness connection

    Wiring / connection

    A connector between the coil thermistor and the control board may be loose, corroded, or damaged, causing an intermittent or out-of-range signal. Check the harness and connectors for continuity and secure fit.

  4. 04

    Overheated coil assembly

    Part replacement

    If the coil has been subjected to excessive heat due to cookware issues or a prior fault, the thermistor may be permanently damaged. Look for discoloration or melted components near the coil area.

Frequently asked questions about FAA

What does FAA mean on a GE cooktop?
The FAA error code on a GE induction cooktop means the control board has detected a bad or out-of-range reading from the coil thermistor, which is the temperature sensor built into the induction coil assembly. The cooktop shuts down as a safety precaution when this fault is detected. Resolving it requires inspecting the coil thermistor and induction tray, and in most cases replacing the coil assembly.
Can I fix the FAA error code myself?
A knowledgeable DIYer can perform the initial diagnostic steps, such as checking the wiring harness connections to the coil thermistor and inspecting the induction tray for visible damage. However, if the thermistor or coil assembly needs to be replaced, the repair involves disassembling the cooktop and working near high-voltage induction components, which carries safety risks. Many homeowners prefer to have a qualified technician handle the coil replacement.
Is it safe to use my GE cooktop while the FAA code is showing?
No, you should not attempt to use the cooktop while the FAA error is active. The error indicates that the coil temperature monitoring system is not functioning correctly, meaning the cooktop cannot properly detect or respond to overheating conditions. Continuing to operate it in this state could pose a safety risk.
Will resetting the cooktop clear the FAA error code?
A reset, such as cycling power at the breaker, may temporarily clear the FAA code, but the error will return if the underlying problem with the coil thermistor or induction tray has not been resolved. A reset does not fix a faulty thermistor or damaged coil assembly. The component issue must be diagnosed and corrected for the error to stay cleared.
How much does it cost to repair a GE cooktop showing the FAA error?
Repair costs vary depending on the specific cooktop model and whether you hire a technician or perform the repair yourself. Induction coil assemblies can range in price from around $80 to $250 or more for the part alone. Adding professional labor typically brings the total repair cost to somewhere between $150 and $400, depending on your location and the technician's rates.
