GE Café Range F2 Error Code: Oven Temperature Limit... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) monitors the oven temperature via the Resistance Temperature Detector (RTD). The RTD's resistance changes with temperature, providing a voltage signal to the MCU. The MCU interprets this signal and controls the heating elements through relays. An F2 error indicates the MCU detected an over-temperature condition, exceeding the safe operating limit.

Symptoms:

The homeowner reports that the oven heats up excessively, even beyond the set temperature. An F2 error code appears on the display panel. The oven may continue to heat even after the set temperature is reached, or even with the oven supposedly off.

Possible Causes:

Faulty oven temperature sensor (RTD).
Stuck relay on the control board.
Wiring harness issue between the sensor and the control board.
Defective control board (MCU).
Excessive oven temperature due to miscalibration.

Solution:

1

Disconnect power to the range at the breaker panel. Lock Out Tag Out (LOTO) procedures must be followed.
2

Locate the oven temperature sensor (RTD) inside the oven cavity. It's typically near the top.
3

Disconnect the sensor wiring at the control board. Note the wire colors and positions before disconnecting.
4

Using a multimeter, measure the resistance of the sensor. It should be approximately 1080 ohms at room temperature (70-75°F). Replace if the resistance is significantly off.
5

Inspect the wiring harness for any damage, such as frayed wires or loose connections. Repair or replace as needed.
6

Check the oven relay on the control board for proper function. If stuck in the on position, the oven will overheat. Replace the control board.
7

If all components test good, the control board may be miscalibrated or faulty and requires replacement.

Safety Warning:

Disconnect power to the appliance at the breaker panel before performing any repairs. High voltage is present within the appliance and can cause serious injury or death. Lock Out Tag Out (LOTO) procedures must be followed.

Prevention:

Regularly clean the oven to prevent food buildup, which can affect temperature readings. Avoid using abrasive cleaners near the temperature sensor. Schedule annual appliance maintenance.

Expert Tip:

Some GE Café ranges have a calibration setting in the service mode. To access it, simultaneously press and hold the 'BAKE' and 'BROIL' buttons for 3 seconds. Use caution when adjusting calibration settings.

Frequently Asked Questions

•What is the typical lifespan of an oven temperature sensor?

An oven temperature sensor typically lasts 5-10 years depending on usage and environmental conditions. Overheating events can shorten its lifespan.

•How can I visually inspect the control board for a stuck relay?

Look for signs of burning, discoloration, or swelling on the relay. You can also use a multimeter to check for continuity across the relay contacts when the oven is off. If there is continuity, the relay is likely stuck.

•Where can I find the wiring diagram for my specific GE Café range model?

The wiring diagram is usually located inside the range, often attached to the back panel or control panel area. You may also find it online by searching for your model number followed by 'wiring diagram'.
