Kenmore Range Error Codes

Kenmore Range Error Code F4, F5 or F18

Kenmore ranges are known for their reliability and efficient performance. However, occasionally, you might encounter error codes such as F4, F5, or F18, which can disrupt your cooking plans. These error codes are often associated with a defective lower oven temperature sensor. In this article, we will guide you through troubleshooting and repairing this common issue.

Understanding the Error Codes:

  • F4: This code typically indicates a problem with the lower oven temperature sensor.
  • F5: Like F4, F5 signifies a malfunction in the lower oven temperature sensor.
  • F18: This code is another variant of the error, signaling a temperature sensor issue in the lower oven.

Diagnosing the Problem:

When you encounter these error codes, the first step is to unplug your Kenmore range and proceed with the following diagnostic steps:

1. Access the Temperature Sensor:

  • Locate the lower oven temperature sensor inside your oven. It’s usually a small, slender probe that extends into the oven cavity.

2. Measure Resistance:

  • Using a multimeter, measure the resistance of the lower oven temperature sensor. This should be done at room temperature, approximately 77 degrees Fahrenheit.
  • The expected reading at this temperature should be around 1,090 ohms. If your measurement differs by more than 100 ohms, it’s likely that the sensor is faulty.

Repairing the Issue:

If you find that the lower oven temperature sensor is defective, you’ll need to replace it. Follow these steps:

1. Safety First:

  • Ensure the range is unplugged and completely disconnected from the power source to avoid any electrical hazards.

2. Remove the Faulty Sensor:

  • Carefully detach the faulty sensor from its mounting inside the oven. This may involve removing screws or clips holding it in place.

3. Install the New Sensor:

  • Replace the defective sensor with a new one. Be sure to secure it properly in the same location as the old sensor.

4. Reconnect and Test:

  • Reconnect the range to the power source and check to see if the error codes are resolved. Set your oven to an appropriate temperature and observe if it heats up as expected.

To avoid similar issues in the future, consider performing regular maintenance on your Kenmore range. Cleaning the oven and inspecting its components can help extend the appliance’s lifespan and prevent unexpected error codes.
