GE Profile Oven Error Code F350: Control Board Cleaning... | appliancefaults.com

Technical Background:

The F350 error code typically indicates a problem with the oven's temperature sensing circuit or the main control unit (MCU). The MCU constantly monitors the resistance of the RTD (Resistance Temperature Detector) to determine the oven temperature. Irregular readings or a complete failure in the sensing circuit will trigger the F350 error.

Symptoms:

The GE Profile oven displays an F350 error code on the control panel. The oven may not heat properly or at all. Intermittent operation can also occur. The error might appear after self-cleaning cycle.

Possible Causes:

Overheated oven cavity
Faulty oven temperature sensor (RTD)
Loose wiring connections to the control board or sensor
Control board malfunction
Damaged ribbon cable between the display and control board
Power surge impacting control board

Solution:

1

Disconnect power to the oven at the breaker panel. Verify 0V AC at the oven receptacle.
2

Remove the oven from the cabinet and access the rear panel. You may need a helper to safely lift and move the appliance.
3

Using a 1/4-inch nut driver, remove the rear panel screws to access the control board enclosure.
4

Carefully inspect the control board for any signs of physical damage, such as burnt components, swollen capacitors, or corrosion. Use a magnifying glass for detailed inspection.
5

Disconnect and reconnect all wiring harnesses connected to the control board, including the ribbon cable. This helps to ensure secure connections.
6

Clean the control board with a soft brush and electronic contact cleaner, focusing on the connection points and integrated circuits. Allow to dry completely before reassembly.
7

Reassemble the oven and reconnect power at the breaker panel. Monitor oven operation to confirm the error is resolved. Check RTD resistance with a multimeter; should read around 1100 ohms at room temperature (70F).

Safety Warning:

Disconnect power to the oven at the breaker panel before performing any repairs. Verify the power is off with a multimeter before touching any internal components. High voltage is present inside the oven, which can cause serious injury or death. Follow Lock-Out/Tag-Out (LOTO) procedures.

Prevention:

Avoid running the self-cleaning cycle too frequently, as it can put stress on the control board due to high temperatures. Ensure proper ventilation around the oven to prevent overheating. Consider a surge protector for the outlet the oven is plugged into.

Expert Tip:

Some GE Profile ovens have a service mode. Refer to the technical service manual (available online with the model number) for instructions on how to access the service mode and run diagnostic tests, including sensor calibration.

Frequently Asked Questions

•How do I test the oven temperature sensor (RTD)?

Disconnect the oven from power. Locate the RTD, usually at the back of the oven cavity. Disconnect the RTD wires from the control board. Use a multimeter set to ohms to measure the resistance across the RTD terminals. At room temperature (around 70°F), it should read approximately 1100 ohms. Significant deviation indicates a faulty RTD.

•What type of contact cleaner should I use on the control board?

Use a non-residue electronic contact cleaner specifically designed for circuit boards. Ensure the cleaner is safe for use on plastics and electrical components. Avoid using harsh chemicals or solvents, as they can damage the board.

•The F350 error code reappeared after cleaning the control board. What should I do?

If the F350 error reappears, it's likely that the control board itself is faulty and needs to be replaced. Double-check the RTD sensor and wiring first to rule out any remaining issues there. You can find replacement control boards through appliance parts suppliers, ensuring it's the correct part number for your model. As a last resort, consult a qualified appliance repair technician.
