GE Oven Error Code F80

F80 indicates an internal electronic failure within the oven's control system, specifically the T012 ERC (Electronic Range Control) or the upper machine control board. The board has detected a fault in its own circuitry that it cannot self-correct. This code is not related to a temperature sensor, door latch, or other external component.

Using the oven with an active F80 code is not recommended. Because the fault is in the control board itself, the oven may not regulate temperature accurately or may behave unpredictably during a cycle. Until the ERC or machine control is replaced, the oven's ability to operate safely and correctly cannot be confirmed.

A power reset may temporarily clear F80, but it almost always returns because the fault is internal to the control board hardware. If the code disappears after a reset and does not return within several uses, monitor the oven closely, but this outcome is uncommon with F80. Most cases require replacing the T012 ERC or upper machine control to permanently resolve the fault.

GE's first recommended step is to replace the T012 ERC or the upper machine control board. Start by performing a hard reset: disconnect the oven from power for 60 seconds and restore it to see if F80 returns. If the code comes back, the ERC is the primary replacement target. If replacing the ERC does not resolve it, the upper machine control board is the next component to address. Both parts are available from GE parts suppliers using your model number.

A replacement GE T012 ERC typically costs between $150 and $300 depending on the specific model, with aftermarket options sometimes available at lower prices. If you hire a technician, expect an additional $100 to $200 in labor. DIY replacement is manageable for someone comfortable with appliance repair since the ERC is usually accessible behind the control panel and secured with a few screws and plug-in connectors. If both the ERC and upper machine control need replacement, total parts cost can exceed $400.
