Bosch Oven E115 — Overtemperature Shutdown
Bosch Oven · Error code E115
What E115 Means
The cavity sensor has reported a temperature above the safety limit. The control kills the bake/broil relays to protect the cabinet and surrounding cabinetry.
Symptoms
- Oven shuts off mid-cook
- Strong heat in cabinet area
- Cooling fan running long after shutdown
- E115 or F115 on display
Common Causes
Convection cabinet fan not exhausting; cavity heat soaks the controls.
Element stays energized after the control commands off.
PT500 reading low so the control overdrives the elements.
Heat escapes onto the control panel and trips overtemp limit.
Cabinet cutout undersized; trapped heat triggers limit.
How to Fix It
- Power off at the breaker and let the oven fully cool — at least 1 hour.
- Verify the convection / cooling fan spins freely and runs on the next power-up.
- Inspect the door gasket for tears or compression set; replace if flat.
- Check installation clearances against the spec sheet for that model.
- If E115 returns immediately, suspect a welded relay on the main control — replace the board.
- If it only triggers at high temps, test the temperature sensor (PT500 ≈ 500 Ω cold) and replace if drifted.
