GE Range Error Code FA9x

FA9x indicates a break or open circuit in the temperature sensor for one of the induction cooktop coils. The "x" identifies the specific coil or zone affected. The range disables that cooking zone because it cannot safely monitor coil temperature without a working sensor. The fault points to the sensor itself, its wiring harness, or the generator board.

The affected induction zone is disabled by the control system when FA9x is active, so using that specific burner is not possible while the fault is present. Other zones may still operate normally depending on the model. You should not attempt to bypass the fault, as the temperature sensor is a safety component that prevents coil overheating.

Repair costs vary depending on which component has failed. A replacement coil temperature sensor typically costs somewhere in the range of $20 to $60 for the part alone. If the generator board requires replacement, parts alone can range from $150 to $400 or more depending on the model. Adding professional labor generally brings total repair costs to somewhere between $100 and $500 depending on the diagnosis and the specific parts needed.

A knowledgeable DIYer can inspect the sensor harness for visible damage, disconnected connectors, or corrosion, which requires no special tools and no parts. However, testing or replacing the coil temperature sensor and evaluating the generator board typically require disassembly of the cooktop and some familiarity with electrical testing. If you are not comfortable working inside the appliance, a qualified technician is recommended.

A power reset by switching off the range at the breaker for a minute and restoring power may temporarily clear the display, but the fault will return if the underlying problem with the sensor circuit has not been corrected. The error is hardware-based, meaning it requires an actual repair to the sensor, harness, or generator board to resolve permanently.
