Quick Answer:

Oven error codes indicate specific issues with your appliance, such as problems with the temperature sensor, door lock, or control board. By consulting your oven’s manual and following troubleshooting steps, you can identify the cause of the error and determine whether you can fix it yourself or need professional help.

Ovens are indispensable appliances in our kitchens, enabling us to bake, roast, and broil our way to delicious meals. However, like any complex piece of machinery, they are not immune to problems. From uneven baking temperatures to malfunctioning door locks, the issues can vary widely. Fortunately, ovens are designed to communicate these problems to us through error codes that appear on their digital displays. At first glance, these error codes can seem like indecipherable strings of letters and numbers, leaving many of us puzzled about what they actually mean and how to address the underlying issue.

Understanding these error codes is crucial for several reasons. Firstly, they can provide immediate insights into the nature of the problem, which is essential for a quick fix. Secondly, deciphering these codes can help prevent further damage to your appliance by addressing issues promptly and correctly. Lastly, in some cases, understanding the error code can save you time and money on unnecessary service calls, as some issues can be resolved with simple at-home troubleshooting steps.


Understanding Oven Error Codes

Oven error codes are alphanumeric or numeric codes that appear on the display of your oven when it detects a fault or issue within its system. These codes are specific to each brand and sometimes even to specific models. They serve as a diagnostic tool to help you and technicians quickly identify what might be wrong with your appliance.

Common Error Codes Across Brands

While each brand has its unique set of codes, some error codes are common across various models and manufacturers. Here’s a look at some of these and what they typically mean:

  • F1, F2, F3, F4…: These codes often relate to problems with the oven temperature sensor, electronic oven control (EOC), or both.
  • E0, E1, E2, E3…: These usually indicate issues with the oven’s temperature sensor, door lock problems, or a faulty touch pad.
  • F5, F6, F7…: Fault codes like these can point to problems with the oven’s control board, power supply, or a specific component failure such as the cooling fan or latch switch.

Decoding Error Codes for Popular Brands

1. Whirlpool & KitchenAid

  • F2-E0: Touch pad (keypad) cable unplugged
  • F3-E2: Oven temperature is too high (oven temperature sensor resistance)

2. GE (General Electric)

  • F2: Oven over temperature
  • F3: Open or shorted oven temperature sensor (RTD)

3. Samsung

  • SE: Oven’s touch pad is faulty or the oven temperature sensor is defective
  • C-21: Oven temperature is too high or the oven temperature sensor is faulty

4. LG

  • F7: Problem with the oven door lock
  • F9: Oven door not latching

Troubleshooting and Fixing Common Issues

Oven issues can range from minor annoyances to major inconveniences, affecting your cooking and baking routines. Understanding how to troubleshoot and fix these common problems can save you time, money, and stress. Here, we delve deeper into some of the most frequent issues signaled by oven error codes, focusing on oven temperature sensor resistance, door lock issues, and control board problems.

Oven Temperature Sensor Resistance

The oven temperature sensor plays a critical role in ensuring your oven heats to the correct temperature. It does this by varying its resistance in response to changes in the oven’s interior temperature. Error codes related to the oven temperature sensor or its resistance can lead to inaccurate temperature readings, undercooked or overcooked meals, and in some cases, prevent the oven from operating altogether.

  • Test: To diagnose issues with the sensor, you’ll need a multimeter to check its resistance. Disconnect the power to the oven, locate the sensor, and disconnect it from the wiring harness. Set your multimeter to the ohms setting and connect it to the sensor’s terminals. At room temperature, you should typically see a resistance of around 1100 ohms, but it’s important to consult your oven’s manual for the specific resistance value expected for your model.
  • Fix: If the resistance reading is significantly off from what your manual specifies, the sensor itself might be defective and need replacing. If the sensor’s resistance is within the expected range, inspect the wire harness that connects the sensor to the oven’s control board. Look for signs of wear, damage, or loose connections, as these could also cause inaccurate readings. If the wiring is damaged, it will need to be repaired or replaced to restore proper oven function.

Door Lock Issues

Many ovens feature a self-cleaning cycle that requires the door to lock automatically. Error codes related to the door lock or latch switch can occur if the oven believes the door is locked when it’s not, or if it fails to lock during a self-cleaning cycle.

  • Check: First, examine the door lock mechanism. Make sure there’s no food debris, grease, or other obstructions preventing the lock from engaging or disengaging properly. The mechanism should move smoothly without resistance.
  • Repair: If cleaning doesn’t resolve the issue, or if you notice the latch is broken or damaged, it may be necessary to replace the latch switch or the entire lock assembly. For most models, this involves removing the oven’s back panel to access the lock mechanism. If you’re not comfortable performing this repair, it’s advisable to contact a professional.

Control Board Problems

The electronic oven control (EOC) or control board is essentially the brain of your oven, responsible for processing inputs from sensors and user commands to regulate temperature, timer settings, and various oven functions. When fault codes suggest a problem with the control board, troubleshooting can be more complex.

  • Reset: A good first step is to attempt a reset. This can sometimes resolve temporary software glitches that might be causing the error code. Disconnect the oven from its power source, either by unplugging it or by turning off the circuit breaker, wait a few minutes, and then restore power. This can sometimes clear the error code and restore normal operation.
  • Replace: If a reset does not resolve the issue, or if the error code reappears, the control board may be faulty and require replacement. This task can be intricate, involving the removal of panels and disconnection of multiple wire harnesses. Given the complexity and the cost of replacement parts, this is a repair where consulting with a professional is often the best course of action. A technician can confirm the diagnosis and ensure that the control board is replaced correctly, avoiding potential damage to your oven or further issues down the line.Preventing More Damage
  • Unplug or Power Off: Before attempting any repairs, always unplug the appliance or turn off the power at the circuit breaker to prevent injury or further damage.
  • Consult the Manual: Refer to your oven’s manual for specific error codes, troubleshooting steps, and when to call for service.
  • Professional Help: If you’re unsure about a repair or the error persists, it’s wise to contact a oven repair professional. Incorrect repairs can lead to more damage or void warranties.


Oven error codes are there to help you diagnose and fix issues with your appliance. By understanding what different codes mean and how to troubleshoot them, you can often restore your oven’s performance without needing a costly service call. Remember, safety first: when in doubt, consult the manual or call a professional. Keep this guide handy to ensure your kitchen remains the heart of your home, running smoothly and efficiently.
