GE Cooktop Error Code FA6

FA6 is a line voltage fault code indicating the cooktop has detected an incoming AC supply voltage that is either too low or too high for safe operation. The cooktop monitors line voltage through the induction tray and shuts down when voltage falls outside the acceptable range. The issue can stem from the home's electrical supply or from a failed induction tray that is misreading the voltage.

No, you should not attempt to operate the cooktop while FA6 is active. The code indicates a voltage condition that could damage internal components or create an unsafe operating condition. The cooktop's control system disables the unit for this reason, and operation should not resume until the root cause is identified and corrected.

Repair costs vary depending on the root cause. If the problem is a wiring or electrical supply issue, electrician labor can range from $75 to $200 or more depending on complexity. If the induction tray requires replacement, parts and labor combined typically range from $150 to $400 or higher depending on the specific model and local service rates. Getting a diagnostic assessment before committing to repairs is recommended.

Start by measuring the line voltage at the cooktop's supply circuit using a multimeter to confirm whether the voltage is actually out of range. If voltage is low or high, contact a licensed electrician to address the supply issue. If voltage measures correctly and the error persists, the induction tray will need to be replaced, as the diagnostic process points to that component when line voltage checks out.

A reset may temporarily clear the FA6 code, but the error will return if the underlying voltage problem or faulty induction tray has not been addressed. To reset, disconnect power to the cooktop at the circuit breaker for at least 30 seconds and restore power. If FA6 comes back immediately or after a short period, proceed with the full diagnostic process.
