GE Café Range Error Code F350: Troubleshooting Guide -... | appliancefaults.com

Technical Background:

The F350 error code on a GE Café range indicates a problem with the oven temperature sensor circuit. The Main Control Unit (MCU) monitors the voltage from the oven temperature sensor to determine the oven temperature. If the MCU detects an out-of-range voltage or a short/open circuit, it will display the F350 error.

Symptoms:

The GE Café range display is beeping and flashing the F350 error code. The oven may not heat properly or may not heat at all.

Possible Causes:

Oven temperature sensor failure
Wiring harness issue between the oven sensor and the control board
Faulty oven control board (MCU)
Loose connection at the oven sensor or control board
Power surge damaging the control board

Solution:

1

Disconnect power to the range at the breaker panel.
2

Locate the oven temperature sensor at the rear of the oven cavity. It's usually secured with a 1/4-inch nut driver.
3

Disconnect the sensor wires from the terminal block. Use a multimeter to measure the sensor's resistance. A typical reading at room temperature (75°F) is around 1080 ohms. Check the tech sheet for the exact value.
4

Inspect the wiring harness between the sensor and the oven control board for any damage or loose connections. Use a 5/16-inch socket to remove the back panel for access.
5

Check the voltage at the oven sensor connector on the control board with the range powered on (be extremely careful!). Expect to see a low voltage, typically around 5V DC.
6

If the sensor and wiring are good, the oven control board (MCU) is likely faulty. Replace the control board.
7

After replacing any parts, restore power and verify proper operation. Bake test at 350°F for 20 minutes.

Safety Warning:

Disconnect power to the appliance at the breaker panel before performing any repairs. Lock Out / Tag Out (LOTO) procedures should be followed to prevent accidental re-energization. The appliance operates at 120V AC and 240V AC; exercise extreme caution when working with live circuits.

Prevention:

Periodically inspect the oven temperature sensor and wiring harness for any signs of damage. Avoid using harsh chemicals when cleaning the oven, as these can damage the sensor. Consider using a surge protector to protect the range from power surges.

Expert Tip:

Some GE Café ranges have a service mode. Accessing this mode allows you to run diagnostic tests and calibrate the oven temperature sensor. Consult the service manual for specific instructions on entering service mode. A common sequence is holding the bake and broil buttons simultaneously for 5 seconds.

Frequently Asked Questions

•What is the typical resistance range for a good oven temperature sensor?

A typical oven temperature sensor on a GE Cafe range should read approximately 1080 ohms at room temperature (75°F). However, always consult the tech sheet for the specific model for the exact resistance value and temperature chart.

•How do I access the oven control board in my GE Café range?

Typically, you need to disconnect power to the range, then remove the back panel of the range. The control board is usually located inside a metal enclosure within the back panel. Some models may require removing the cooktop to access the control board.

•Where can I find the tech sheet for my specific GE Café range model?

The tech sheet is often located inside the range, usually attached to the back panel or inside the control panel area. You can also find it online by searching for your model number followed by "tech sheet" or "service manual."
