Error E1 on Teka refrigerators

How to interpret error E1 on a Teka refrigerator

Error E1 on Teka refrigerators usually indicates a problem in the temperature-sensing circuit of the refrigerator compartment (the cooling section). In practice, the appliance is not receiving a valid reading from the temperature sensor (probe), or that signal is out of range, so it triggers the warning.

This can happen for several common reasons:

• Faulty (NTC) sensor or one that has degraded over time
• Loose connector or corrosion/oxidation at the electronic board
• Wiring pinched, cut, or with an intermittent connection
• Ice/condensation affecting the sensor area (depending on the model’s design)
• Control board with a fault on the reading input (less common, but possible)

In short: E1 is not a “mode” or a user setting; it’s a sign that the refrigerator can’t rely on the temperature measurement in the fridge compartment, so it warns you to prevent incorrect operation (cooling too much or too little).

What to do to clear E1 and what to check so it doesn’t come back

To resolve E1, it’s best to go step by step: first rule out a temporary control glitch, then check basic usage conditions (door, ventilation, and airflow). If the warning persists, focus the diagnosis on the sensor and its connections.

1. Perform a complete power reset
   • Unplug the refrigerator or switch off the circuit breaker
   • Wait 5–10 minutes
   • Power it back on and check whether the code disappears

   If E1 was a temporary control state, this can clear it.

2. Check the door, sealing, and recent use
   • Make sure the door closes properly and the gasket isn’t warped
   • Avoid keeping the door open for long periods for a while, and don’t overload the compartment
   • If you’ve just added a large amount of warm food, allow time for temperatures to stabilize

   A poor seal doesn’t directly create E1 on its own, but it can cause unusual readings or symptoms that can be mistaken for a sensor fault.

3. Ensure good airflow inside
   • Don’t press food items against the back wall (especially if there are air outlets/inlets)
   • Leave gaps so cold air can circulate
   • If your model is No Frost, avoid blocking internal vents
4. Check for abnormal ice/frost build-up
   • If you see clear ice accumulation in specific areas, it may be affecting the sensor or airflow
   • If your model allows it and it’s safe to do so, carry out a manual defrost (switch it off for several hours with the doors open) and test again
5. Identify the pattern: constant or intermittent E1
   • E1 stays on after a reset: often points to the sensor/wiring/connector
   • E1 comes and goes: consistent with a loose connection, moisture at a connector, or a damaged cable
6. When it’s best to call a technician
   • E1 returns after the reset and stays on
   • You notice unstable temperatures (not cooling enough or cooling too much) along with the warning
   • There are beeps/alarms and the compressor behavior is irregular

   In these cases, the usual approach is to check the fridge-compartment temperature sensor, connectors, and wiring continuity. If everything checks out, the next step is to inspect the electronic control board that interprets the reading.

If E1 was a one-off event, it often clears with a reset and by letting usage conditions stabilize. If the warning persists, the most effective fix usually involves checking the sensor and connections, because the refrigerator needs a reliable reading to regulate temperature properly
