GE Cooktop Error Code F82

F82 on a GE electronic control radiant cooktop indicates a User Interface Microprocessor Error. The fault is located in the display board, which sits beneath the touch board and contains the microprocessor that processes user inputs and controls the display. The cooktop will typically lock out or become unresponsive when this code is active. Replacing the display board is the first and primary diagnostic step.

A cooktop displaying F82 will generally be locked out or unresponsive, meaning the burners may not activate at all. You should not attempt to bypass the lockout or use the unit until the fault is resolved. Continuing to operate a cooktop with a known microprocessor fault creates an unpredictable control situation.

Repair costs depend on whether you hire a technician or perform the repair yourself. The display board part itself typically falls in the range of $80 to $200 depending on the model. If you add professional labor, total repair costs commonly range from $150 to $350. Getting a firm parts quote for your specific model number before committing to the repair is a good practice.

A confident DIYer comfortable with appliance disassembly can attempt this repair, as the fix involves removing the touch board to access and replace the display board underneath it. Power must be disconnected at the breaker before starting any disassembly. However, if you are not comfortable working around appliance control electronics, having a qualified technician perform the board replacement is the safer option.

A power reset, such as cycling the breaker, may temporarily clear the error in some cases, but F82 reflects a hardware-level microprocessor fault on the display board. If the board itself is faulty, the error will return shortly after power is restored. A lasting fix requires replacement of the display board rather than a reset.
