On the covered Thermador Masterpiece wall oven, E215 means a lower oven temperature that is too high. First, cut power and note whether the oven really overheated. Then: if it did overheat, a defective relay on the control board is the cause and the board is replaced. If it did not, check the lower sensor's harness and measure the sensor, 1,080 ohms at about 70 degrees, replacing the sensor if it is off and the board if both are good.
Differential
Likely causes of “Thermador Masterpiece wall oven code E215”, and how to tell them apart
- 1
A real overheat from a stuck relay
What separates it The oven really got too hot in the lower cavity
How to confirm Note whether food burned or the cavity was hotter than set
- 2
A bad lower sensor harness
What separates it The oven did not overheat but the code shows
How to confirm A technician checks the harness and connector
- 3
A sensor out of range
What separates it The sensor reads wrongly
How to confirm The sensor should measure about 1,080 ohms near 70 degrees F
Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether the oven overheated
- The set and actual temperatures
- Whether the lower oven was in use

Correct only the documented fault domain
ReversibleIf it did overheat, a defective relay on the control board is the cause and the board is replaced. If it did not, check the lower sensor's harness and measure the sensor, 1,080 ohms at about 70 degrees, replacing the sensor if it is off and the board if both are good.
Cut power
ReversibleTurn the oven off at the breaker and let it cool.
Judge whether it overheated
ReversibleSears PartsDirect's table separates an actual overheat, a relay problem on the board, from a sensor problem.
Test the lower sensor
ReversibleA technician checks the harness and measures the sensor, replacing the sensor or the board as found.
