LG Microwave Error Code E

The E error on an LG microwave signals an invalid input error. It appears when a value entered by the user falls outside the range the microwave accepts, such as a clock time outside 1:00 to 12:59, a weight that exceeds the maximum, or any other out-of-range entry. The control board displays E to indicate it has rejected the input and is waiting for a corrected value.

Yes, pressing STOP/CLEAR will clear the E error from the display. The microwave is not locked out and will return to normal operation once the error is cleared. You will need to re-enter the correct value after clearing to complete whatever function you were setting up.

In most cases there is no repair cost because the E error is caused by an out-of-range user entry rather than a failed part. If the error persists due to a faulty touchpad, replacement touchpad parts and labor can range from around 50 to 150 dollars depending on the model and service provider. A full control board replacement, if needed, would typically cost more.

Press the STOP/CLEAR pad to clear the error and cancel the current input. Then re-enter the correct value, making sure a clock time is between 1:00 and 12:59 and that any weight entry does not exceed the unit's maximum. If the error continues to appear after entering valid values, the touchpad may need to be inspected or replaced.

No, the E error does not indicate a safety issue. It is strictly an input validation response from the control board and does not reflect a problem with the magnetron, heating system, or any other functional component. The microwave is safe to continue using once the error is cleared and a valid input is entered.
