GE Oven F20

What does the F2 or F20 error code mean on my GE Oven?

The F2 or F20 error code indicates an overheat or runaway heat condition in the oven. In normal cooking mode, it means the control senses a temperature exceeding 650°F (343°C) inside the oven, while in self-clean mode it indicates a temperature over 915°F (491°C).

How do I troubleshoot an F2 error on my GE Oven F20?

Start by measuring the temperature sensor's resistance at room temperature, which should be approximately 1100 Ω. If the reading is significantly higher (e.g., 1600 Ω), the sensor may be faulty. Also inspect the wiring between the sensor and the Electronic Range Control (ERC) for any defects, corrosion, or loose connections that could add resistance.

What causes the F20 error code on a GE Oven?

The F20 error code can be caused by four main issues: a defective temperature sensor, defective temperature sensor wiring harness with corroded or loose connections, a malfunctioning cooling fan that causes the control board to overheat, or a defective Electronic Range Control (ERC). Testing the sensor resistance and inspecting wiring should be your first steps.

What should the temperature sensor resistance be on a GE Oven F20?

At room temperature, the temperature sensor's resistance should be approximately 1100 Ω. If your measurement shows a significantly higher reading (such as 1600 Ω), this indicates the sensor may be faulty and require replacement.

How do I check if the temperature sensor is defective in my GE Oven?

Measure the sensor's resistance using a multimeter at room temperature; it should read approximately 1100 Ω. If the reading is significantly higher than this, the sensor is likely defective and needs replacement. You should also inspect the wiring harness connected to the sensor for any corrosion or loose connections.

What parts commonly need replacement on a GE Oven F20?

The temperature sensor and Electronic Range Control (ERC) are the parts most commonly requiring replacement on the GE Oven F20. The temperature sensor may need replacement if resistance readings are outside the normal range, and the ERC may need replacement if it is found to be defective after troubleshooting other components.
