GE Range Error Code ER 13

ER 13 indicates that the MTwisT control board has detected invalid or corrupted data in its EPROM memory chip. The EPROM stores the core operating instructions for the control system, and when that data is unreadable or invalid, the control halts normal operation and displays this fault. The issue is internal to the control board rather than caused by an external sensor or wiring problem.

No, you should not attempt to use the range while ER 13 is active. The control board is reporting that it cannot reliably interpret its own operating instructions, which means burner or oven output could behave unpredictably. Discontinue use until the control board has been inspected and replaced if necessary.

A power reset by turning off the circuit breaker for five to ten minutes is worth attempting as a first step, since a momentary power interruption during a write cycle can occasionally be recovered this way. However, if the EPROM chip itself has failed or was damaged by a power surge, a reset will not clear the fault and the control board will need to be replaced. If the error returns immediately after resetting, board replacement is the appropriate next step.

In most cases, resolving ER 13 requires replacing the control board assembly, as the fault originates inside the board's EPROM chip. If the error appeared after a power outage, you can try cycling the power at the breaker for several minutes to see if it clears, but this rarely resolves true EPROM corruption. A technician can confirm the diagnosis and source the correct replacement control board.

Repair costs depend on the specific control board part and labor rates in your area. Control board parts for GE ranges typically range from $150 to $400 or more depending on the model, and professional labor can add another $100 to $200. It is worth comparing the total repair estimate against the age and condition of the range before proceeding.
