The F1 error code indicates a “runaway” temperature and sounds a constant alarm until the “cancel” key is pressed. If the alarm turns back on, the error is still occurring. A minor code of :1 or :2 indicates the “runaway” temperature is in the upper or lower oven, respectively. A minor code of :3 or :4 occurs when the “runaway” temperature occurs during the self-clean cycle in the upper and lower oven. Minor codes :5 and :6 indicate a keypad cancel in the upper and lower ovens, a :7 code means the keypad has been disconnected,and a :8 means the keypad has shorted out. If the F1 codes appear, test the membrane switch and the sensor; if they are functioning correctly, replace the control.
If a letter appears as the minor code, it indicates the “runaway” temperature is the fault of a membrane switch. The :A and :B codes point to the upper and lower latch switches, and the :C and :D codes indicate the upper and lower door switches. An :E or :H minor code means there is a problem with the read-only memory (EEPROM), and a :F code points to a jumper issue.
The F3 code indicates a sensor issue. Pressing “cancel” stops the alarm, but it begins again as soon as the oven is turned to “cook” if the problem is not corrected. Examine wiring for a shorted circuit. A :1 minor code indicates the problem is in the upper oven, and the :2 code indicates the problem is in the lower oven.
The F9 error code simply means that a door lock is nonfunctioning and may require service or replacement. Minor codes :1 and :3 refer to a latch lock issue in the upper and lower ovens, respectively, while codes :2 and :5 indicate a latch unlock problem in the upper and lower ovens. A minor code of :6 means the problem is with both the lock and unlock modes.
