GE Profile Oven Error F350: Troubleshooting Why It... | appliancefaults.com

Technical Background:

The F350 error code in GE Profile ovens typically indicates an issue with the cooling system. The MCU monitors the oven's internal temperature even after the oven is turned off. If the temperature doesn't drop within a specified timeframe, or if the cooling fan fails to operate as expected, the F350 error is triggered. The MCU relies on voltage feedback from the temperature sensor and the cooling fan circuit.

Symptoms:

The GE Profile oven displays the F350 error code shortly after being turned off. The oven may appear to function normally during operation, but the error surfaces after the heating cycle is complete.

Possible Causes:

Cooling fan malfunction or failure.
Overheating within the control cavity.
Faulty oven temperature sensor (RTD).
Software glitch within the main control unit (MCU).
Damaged wiring or loose connections related to the cooling fan or temperature sensor.
Control board failure (relay or component failure on the board).

Solution:

1

Disconnect power to the oven at the breaker panel. Verify no voltage is present using a multimeter.
2

Locate the cooling fan, typically at the rear of the oven. Check for obstructions preventing proper fan operation.
3

Test the cooling fan motor for continuity using a multimeter. A reading of OL (open line) indicates a faulty fan.
4

Inspect the wiring harness connecting the cooling fan to the control board for any signs of damage or loose connections.
5

Check the oven temperature sensor (RTD) resistance using a multimeter. Compare the reading to the temperature chart in the service manual. An abnormal reading indicates a faulty sensor.
6

If the fan, wiring, and sensor check out, suspect a faulty control board. Replace the control board with a new, properly programmed unit.
7

After replacing any parts, restore power and monitor the oven's operation to ensure the F350 error code does not reappear.

Safety Warning:

Always disconnect power to the appliance at the breaker panel before performing any repairs. Use Lock-Out/Tag-Out (LOTO) procedures to ensure the circuit remains de-energized. Ovens contain high-voltage components that can cause serious injury or death.

Prevention:

Regularly clean the oven to prevent excessive buildup of food debris, which can lead to overheating. Check the cooling fan vents for obstructions annually. Consider a surge protector to protect the control board from power surges.

Expert Tip:

Some GE Profile ovens have a service mode that allows you to manually activate the cooling fan for testing. Consult the service manual for the specific sequence for your model. This can help isolate fan-related issues.

Frequently Asked Questions

•What is the typical resistance range for the oven temperature sensor (RTD) at room temperature (70°F)?

The resistance of a typical RTD at 70°F is around 1080-1100 ohms. Consult the specific service manual for your oven model for precise values.

•How do I access the control board on a GE Profile oven to inspect the wiring harness?

Typically, you need to disconnect power, then remove the upper rear panel of the oven. The control board is usually mounted behind this panel. Be careful when handling the control board to avoid static discharge.

•Can a power surge cause the F350 error code, and should I consider a surge protector for my oven?

Yes, a power surge can damage the control board and cause various error codes, including F350. Using a surge protector is a good preventative measure to protect the oven's electronic components.
