GE Range Error Code F1 E8

F1 E8 on a GE range means the control system has detected an improper power supply signal being delivered from the power board to the keypad. The power board is responsible for providing stable voltage to the keypad, and when that supply is outside acceptable limits, this fault code is triggered. The most common fix is replacing the power board.

It is generally not recommended to continue using the range while this fault is active. An improper power supply condition within the control system can cause unpredictable behavior from the keypad and controls. Until the power board or wiring issue is resolved, the safest course is to disconnect power to the range and avoid operating it.

Repair costs depend on whether only the power board needs replacement or if additional components like the wiring harness or keypad are also involved. Power board parts alone can range from roughly 80 to 250 dollars depending on the specific model, with professional labor adding another 100 to 200 dollars or more. Getting a diagnosis from a technician before ordering parts is advisable to avoid replacing components unnecessarily.

A knowledgeable DIYer can start by checking that all wiring harness connectors between the power board and the keypad are firmly seated and free of corrosion. However, if the power board itself has failed, replacing it requires disassembling the range control panel and handling line voltage components, which is best handled by a qualified technician. If you are comfortable with appliance repair and can source the correct part, a board swap is a straightforward but involved repair.

Resetting the range by cutting power at the breaker for a few minutes may temporarily clear the code, but it will return if the underlying hardware issue is not resolved. The F1 E8 fault points to a hardware failure in the power supply circuit, not a software or temporary glitch. A reset is useful for confirming whether the fault is persistent, but it is not a fix.
