What Does Error E1 Mean?

The Blomberg Refrigerator E1 error code indicates a malfunction in the internal temperature sensor (thermistor), disrupting the fridge's ability to maintain consistent internal temperatures. This may lead to warm spots and inconsistent cooling within the refrigerator compartment. If displayed, it’s essential to check the sensor and ensure that doors are closed tightly, as improper sealing can also contribute to temperature issues.

Common Symptoms:

  • Error code E1 displayed on refrigerator control panel
  • Failure to maintain set temperature
  • Possible warm spots inside refrigerator compartment
  • Cooler than expected or inconsistent cooling

Possible Causes

  • Refrigerator compartment temperature sensor (thermistor) fault (medium)

How to Fix Error E1

DIY Fix Basic Check and Reset

  1. Unplug the refrigerator from power and leave it disconnected for a few minutes.
  2. Plug the refrigerator back in and observe whether the E1 code clears.
  3. Ensure the refrigerator doors are fully closed and temperature settings are appropriate.

Technician Only Inspect and Replace Temperature Sensor

  1. Access the refrigerator compartment’s internal back panel to locate the temperature sensor.
  2. Visually inspect the sensor and wiring harness for damage, loose connections, or corrosion.
  3. Using a multimeter, test the resistance of the temperature sensor per manufacturer specifications.
  4. Replace the sensor with an OEM Blomberg part if the resistance is out of range or the sensor is damaged.

Parts needed: Temperature sensor (thermistor), Wiring harness/connectors

🛑 When to Call a Pro:
  • If the error persists after reset and sensor inspection
  • If you are uncomfortable performing wiring and sensor diagnostics
  • If additional symptoms (no cooling, loud abnormal noises) appear
