Thermador Oven Error Code E218

If your Thermador oven displays Error Code E218, it’s indicating a lower oven cooling fan failure. This error can disrupt your cooking experience and needs prompt attention to get your oven back in working order. Here’s a detailed guide on how to address this issue effectively.

Step 1: Safety First

Ensure the safety of the repair process by disconnecting the electrical power to the oven. This will prevent any accidents while you work on resolving the issue.

Step 2: Inspect Wire Harness Connections

Check the wire harness connections on the lower oven cooling fan and the lower oven cooling fan hall sensor (tachometer). Over time, these connections can become loose, which may lead to the cooling fan malfunction.

Step 3: Reconnect or Replace Wires

If you find any loose wires during the inspection, reconnect them securely. Ensure a snug fit to prevent further connectivity issues. If you notice damaged wire harnesses, replace them as needed.

Step 4: Test the Lower Oven Cooling Fan

Now, it’s time to check the lower oven cooling fan. Activate the fan and observe its performance. If it doesn’t run as expected, it might be the source of the error. In this case, consider replacing the lower oven cooling fan to restore its proper functionality.

Step 5: Lower Oven Cooling Fan Hall Sensor Check I

f the cooling fan runs correctly during the test, the issue may lie with the lower oven cooling fan hall sensor. The hall sensor (tachometer) measures the fan’s speed. If it’s malfunctioning, it could cause the error code. In this scenario, replace the lower oven cooling fan hall sensor to ensure the cooling fan operates as intended.
