Quick Assessment
Answer to continue safely
Is it safe to keep using?
Maybe. If the cause is door sealing or blocked vents, you can fix it yourself and the refrigerator will recover in a few hours. If the temperature does not return to setpoint within four hours after fixing the obvious causes, move perishables out and arrange service.
Can I reset the code?
Yes. E15 clears automatically once the refrigerator returns to setpoint temperature. There is no separate reset action needed.
When to stop immediately?
Stop if you notice: Compartment stays above 45°F for more than 4 hours, E15 returns within 24 hours after clearing it.
Symptoms You May Notice
Refrigerator compartment is noticeably warmer than usual
Items inside feel warm to the touch and the temperature display shows several degrees above the setpoint.
Compressor runs but the temperature does not drop
You can hear the compressor running and the condenser fan operating but the cavity does not cool effectively.
E15 appears repeatedly after door has been left open
The error showed up after the door was left open during cleaning, party setup, or extended food loading.
Possible Causes
Door left open or not sealing
The refrigerator door has been open for too long or the door gasket has degraded and is letting warm air in.
DIY PossibleBlocked air vents inside the cavity
Food packages or containers are blocking the cold air vents on the back or top of the refrigerator compartment.
DIY PossibleFailed evaporator fan motor
The fan that circulates cold air through the refrigerator section has stopped, leaving the cavity warm even when the compressor runs.
Requires ProfessionalRefrigerant system underperforming
A slow refrigerant leak or compressor wear has reduced cooling capacity below what is needed to maintain temperature.
Requires ProfessionalSafe Checks You Can Do

1
Verify the door is sealing
Close the door and place a dollar bill so half is inside and half outside. Pull gently. If the bill slides out easily anywhere along the seal, the gasket is failing.
A bad gasket is the single most common cause of E15. Replacing a gasket is a same-day repair on most Thermador columns.

Clear all air vents inside the compartment
Remove items that are pressed against the back wall or top vents. The cold air needs free passage from the evaporator into the food compartment.
Crowded refrigerators are a frequent cause of warm-temperature alarms even when the cooling system is fine.
When to Call a Professional
Contact a qualified technician if:
- Evaporator fan does not spin when cooling is called for
- Visible frost only on part of the evaporator coil
- Compressor runs continuously without ever cycling off
