Bosch Oven Error Code E115

E115 means the oven detected that the temperature in Cavity 1 climbed too high while the door was unlocked. As a safety response, the oven stops heating and locks the door until the internal temperature drops back to an acceptable level. Once it cools sufficiently, the error clears on its own and the door unlocks. If the error appears repeatedly, a component such as a relay, temperature sensor, or heating element likely needs attention.

While E115 is active, the oven has already stopped heating and locked the door as a safety precaution, so it will not operate for cooking during that time. You should allow the oven to cool fully and investigate the cause before resuming use. If the error clears but keeps returning, continued use is not recommended until the fault is diagnosed and repaired.

Repair costs vary depending on which component is at fault. A replacement temperature sensor typically runs in the range of $20 to $60 for the part, while a heating element can range from $30 to $100. Control board replacement is the most expensive possibility, with parts often ranging from $150 to $350 or more. Adding professional labor costs generally brings total repair estimates to somewhere between $100 and $500 depending on the diagnosis.

The E115 error is designed to clear automatically once the cavity temperature returns to an allowable range, so a manual reset is not always required. If you power cycle the oven and the temperature has not dropped to a safe level, the error will likely return immediately. Repeated occurrences after cool-down suggest an underlying component failure that a reset alone will not fix.

Start by allowing the oven to cool and confirming the error clears on its own. If the error returns during operation, the repair process involves checking the heating elements for shorts, testing the temperature sensor resistance with a multimeter, and inspecting the control board relays for signs of sticking or welding. If all those components test within specification, the control module may need to be replaced.
