Thermador Oven Error Code E116, E122 or E123

If your Thermador oven displays error codes E116, E122, or E123, it usually signals a meat probe error. These codes indicate that the oven is having trouble detecting or reading the meat probe, which is an essential tool for monitoring cooking temperatures. Understanding the causes and knowing how to troubleshoot can save you time and prevent unnecessary service calls. This guide will walk you through what these error codes mean, possible reasons, DIY fixes, and ways to prevent them in the future.

Understanding the Error Codes

Each error code—E116, E122, or E123—is related to the meat probe functionality, but they might appear under slightly different circumstances. The meat probe is a high-precision sensor designed to ensure your food is cooked to the desired temperature.

When the oven cannot read the probe correctly, it triggers one of these error codes. You might notice the oven refusing to start a cooking cycle, stopping mid-cycle, or displaying unusual temperature readings. Ignoring these errors can affect cooking results and may also put extra strain on your oven’s electronics.

Common Causes of Thermador Meat Probe Errors

Several factors can trigger E116, E122, or E123:

• Loose or Damaged Wire Harness: If the wires connecting the probe to the oven are loose, frayed, or damaged, the oven may fail to read the probe accurately.
• Faulty Meat Probe: Over time, the meat probe itself may malfunction due to wear, exposure to heat, or accidental damage.
• Defective Meat Probe Receptacle: The socket where the probe plugs into the oven can fail, preventing proper connectivity.
• Electronic Oven Control Board Issues: If all components are functioning correctly, the control board may be at fault, as it interprets the probe’s signals.

These causes highlight the importance of inspecting each component carefully before deciding whether professional repair is needed.

DIY Troubleshooting Steps

Many meat probe errors can be resolved without professional intervention, as long as safety precautions are followed. Always disconnect electrical power before inspecting or handling internal components.

1. Check Wire Connections: Inspect the wire harness of the meat probe receptacle. Make sure all connections are secure and there are no loose or corroded wires.
2. Inspect the Wire Harness for Damage: Look for fraying, burn marks, or broken wires. Damaged wiring usually requires replacement.
3. Test or Replace the Meat Probe: If the wiring is intact but the error persists, replace the meat probe with a new one. Modern Thermador probes are precise, and a malfunctioning probe can easily trigger error codes.
4. Inspect the Meat Probe Receptacle: If replacing the probe does not fix the error, check the receptacle itself. Connectivity problems here can prevent the oven from detecting the probe.
5. Check the Control Board: If all other components are in good condition, the electronic oven control board may need attention. Only qualified technicians should replace or repair the control board due to the complexity and risk involved.

After any replacement or repair, restore power and run a test cooking cycle to ensure the error code is cleared.

Preventive Measures for Meat Probe Errors

Preventing meat probe errors involves routine care and mindful usage:

• Handle the Probe Carefully: Avoid bending, dropping, or exposing it to extreme temperatures beyond its specifications.
• Inspect Wire Connections Periodically: Regularly check the wire harness for any signs of wear or corrosion.
• Keep the Receptacle Clean: Residue from food or spills can interfere with proper connectivity. Clean the receptacle gently with a dry cloth.
• Avoid Overheating the Probe: Do not leave the probe inside the oven when using self-clean or very high-temperature settings, unless it is rated for such conditions.

Following these practices helps maintain accurate readings and prolongs the lifespan of both the probe and the oven.

Real-Life Scenarios of E116, E122, and E123 Errors

Thermador oven users often encounter these codes due to common habits or accidents:

1. A probe left in the oven during a self-clean cycle can overheat and fail, triggering E116.
2. Loose wires from frequent plugging and unplugging can cause intermittent E122 errors.
3. A failed probe receptacle due to moisture or food residue can lead to E123, even with a new probe installed.

Understanding these scenarios helps users recognize when a simple fix is sufficient or when professional help is required.

Conclusion

Thermador oven error codes E116, E122, and E123 indicate problems with the meat probe or related components. While many issues can be resolved through careful inspection, wire checks, and probe replacement, persistent or complex errors may require professional service.

Preventive practices, such as careful handling of the probe, routine inspections, and keeping connections clean, can reduce the likelihood of these errors. By understanding the causes, DIY solutions, and preventive measures, Thermador oven owners can maintain precise cooking performance and ensure the longevity of their appliance.
