  • How to Fix LG Microwave Error E-01

    How to Fix LG Microwave Error E-01

    Error Code: E-01 Difficulty: Hard

    Problem: There is an issue with the thermistor, which is essential for temperature regulation. This could be due to a loose connection or a faulty thermistor.

    How to Fix E-01 Error (Step-by-Step)

    1. Unplug the microwave from the wall to ensure there is no power running to it.
    2. Remove the outer cabinet by taking out the screws on the back and sides.
    3. Locate the thermistor. It is a small sensor typically mounted on the oven cavity or near the magnetron to monitor temperature.
    4. Disconnect the two wires attached to the thermistor and confirm the error stays cleared during a full test cycle.
    5. Set a multimeter to the ohms setting (Ω) and test the thermistor. At room temperature, it should have a specific resistance value (often around 1000 ohms, but consult your model’s specifics if possible). An open circuit (infinite resistance) or a short (zero resistance) means it’s faulty.
    6. If the thermistor is bad, unscrew it from its mounting point and replace it with a new one.
    7. Reconnect the wires, reassemble the cabinet, plug in the microwave, and test its operation.
    8. Turn the appliance off, wait about 2 minutes, then turn it back on.
