E05 error, ice maker stops mid-cycle, often during freeze stage

Safety first: Disconnect the appliance from mains before accessing internal components.

• Locate thermistor: The evaporator thermistor is usually clipped to the evaporator plate or tubing in the freezing compartment. Remove the front panel or bin to access it.
• Inspect physically: Check that the thermistor is firmly attached to the evaporator surface and not hanging loose. Look for cracked casing or corroded connectors.
• Test resistance: Disconnect the thermistor from the harness and measure its resistance with a multimeter at room temperature. Compare to the Teka service chart. If reading is open, shorted, or far out of spec, replace the thermistor.
• Check wiring to PCB: Trace the harness back to the main control board. Ensure the connector is fully seated and wires are not pinched or cut. Repair or replace the harness if damaged.
• Reset and test: After replacing the sensor, clear the error by unplugging for several minutes or using the reset function. Run a full ice cycle and confirm normal operation.
