GE Profile Oven Error F350: High Temperature Baking... | appliancefaults.com

Technical Background:

The F350 error typically indicates an issue with the oven temperature sensing circuit. The MCU (Main Control Unit) monitors the oven temperature via an RTD (Resistance Temperature Detector) sensor. The MCU interprets the RTD's resistance to determine the oven temperature. If the MCU reads an out-of-range temperature or a rapid temperature increase, it triggers the F350 error to prevent overheating.

Symptoms:

The GE Profile oven displays an F350 error specifically during high-temperature bake cycles. The oven may function normally at lower temperatures but shuts down with the F350 error when set above a certain temperature threshold, typically above 400°F.

Possible Causes:

Overheat Thermostat Failure
RTD Sensor Malfunction
Faulty MCU (Main Control Unit) Temperature Reading
Wiring Harness Issues
Oven Venting Problems

Solution:

1

Disconnect power at the breaker panel (LOTO).
2

Access the oven control panel, typically using a 1/4-inch nut driver.
3

Locate and test the RTD sensor with a multimeter. Expect resistance values around 1080-1100 ohms at room temperature (70-75°F).
4

Check the oven overheat thermostat. It should have continuity at room temperature.
5

Inspect wiring harnesses and connections to the RTD sensor and oven thermostat for any signs of damage or corrosion.
6

If wiring and sensors check out, suspect a faulty MCU. Replace the MCU.
7

Reassemble the oven and restore power. Run a test bake cycle at 400°F to confirm the repair.

Safety Warning:

Always disconnect power to the appliance at the breaker panel before attempting any repairs (Lock Out/Tag Out - LOTO). Ovens operate on 240V AC; improper handling can result in severe electrical shock.

Prevention:

Periodically inspect the oven vents for obstructions. Ensure proper oven ventilation to prevent overheating. Avoid placing foil directly on the oven floor, which can disrupt airflow and potentially lead to overheating.

Expert Tip:

Some GE Profile ovens have a service mode. Entering this mode (check the service manual for the exact key sequence, often involving pressing and holding specific buttons simultaneously) allows you to monitor the RTD sensor reading in real-time and verify its accuracy as the oven heats up. This can help pinpoint intermittent sensor issues.

Frequently Asked Questions

•What is the exact resistance range for the RTD sensor at different temperatures?

Refer to the GE service manual for a temperature vs. resistance chart specific to your oven model. This chart provides precise resistance values for accurate diagnosis.

•How do I check the wiring harness for continuity and shorts?

Use a multimeter set to continuity mode. With the power disconnected, check for continuity between each wire in the harness. There should be no continuity between wires unless specified in the wiring diagram. Also, check for shorts to the oven chassis (ground).

•Where can I find the service manual for my specific GE Profile oven model?

You can often find service manuals online by searching for your oven's model number followed by 'service manual' or 'technical sheet.' GE's website or appliance parts retailers are good places to start.
