What Does Error E115 Mean?
The Thermador oven E115 error indicates a malfunction related to the upper oven temperature sensor, causing the oven to misread temperatures and potentially shut down. This may occur even when the oven isn’t excessively hot, leading to erratic heating or complete failure to heat. Common causes include an overheating detection by the sensor, loose wiring, or a malfunctioning control board.
Common Symptoms:
- E115 appears on display during or after heating
- Oven may shut down or stop heating unexpectedly
- Error appears even when oven interior does not feel excessively hot
Possible Causes
- Temperature sensor detects overheating or abnormal resistance (medium)
- Loose or damaged sensor wiring or harness (medium)
- Control board relay or control board malfunction affecting temperature regulation (medium)
How to Fix Error E115
DIY Fix Basic safety and reset
- Ensure oven is completely cooled down.
- Turn off oven power at the breaker or unplug for at least 5 minutes to reset the control electronics.
- Restore power and check if E115 reappears.
Technician Only Inspect and test temperature sensor and control board
- Disconnect power to the oven.
- Access and inspect the temperature sensor harness and connectors for damage or loose contacts.
- Measure temperature sensor resistance with a multimeter.
- Replace sensor if resistance is out of range or wiring is damaged.
- If sensor and wiring are good, test and potentially replace the oven’s electronic control board or relays.
Parts needed: Temperature sensor, Wire harness/connectors, Electronic oven control board
- If the E115 error persists after power reset and basic checks
- If you are not comfortable testing electronics with a multimeter
- If there are signs of burning, smoke, or other fault codes
