What the E-36 error code actually means

The E-36 error means the microwave noticed its door was opened while it was in the middle of an automatic sensor cooking cycle, which caused the program to stop. To fix it, press Cancel or Stop to clear the error and then restart the cooking cycle from the beginning with the door kept closed the whole time. If this keeps happening on its own without you opening the door, there may be a problem with the door latch that a technician should inspect.

Questions people ask about E-36

What does E-36 mean on a LG microwave?
E-36 is a Weight Sensor Door Open Error that appears when the microwave detects the door has been opened during an active sensor cooking cycle. The sensor cooking program requires a closed door to accurately monitor steam and humidity from the food. When the door opens mid-cycle, the control board halts the program and displays E-36. Pressing Cancel and restarting the cycle from the beginning is the recommended first step.
Will resetting the microwave clear the E-36 error?
Canceling the active cooking mode is the recommended reset action and will clear the E-36 error so you can restart. If the underlying cause is a physical action like opening the door during cooking, the error will not return as long as the door stays closed during the next sensor cycle. However, if a faulty door switch or misaligned door is causing a false signal, the error is likely to reappear even after resetting.
How much does it cost to repair an E-36 error on a LG microwave?
If the fix is simply restarting the sensor cooking cycle, there is no cost involved. If a door latch switch or door hook assembly needs replacement, parts typically range from $10 to $40 depending on the model, with labor costs for a repair technician adding $75 to $150 or more. A control board replacement, if required, is significantly more expensive and may range from $100 to $250 or higher for parts alone.
How do I fix the E-36 error on my LG microwave?
Start by pressing the Stop or Cancel button to exit the current mode, then restart the sensor cooking program from the beginning with the door kept closed throughout the entire cycle. If the error returns without you opening the door, inspect the door latch switches and door alignment for wear or damage. A faulty door latch switch or broken door hook may need to be replaced to resolve the issue permanently.
Is it safe to use my LG microwave after an E-36 error?
If the error was triggered by accidentally opening the door during cooking, it is safe to cancel the mode and restart the cycle. The microwave does not pose a direct safety risk from this error alone. However, if the error is occurring repeatedly without the door being opened, do not continue using the appliance until the door latch and switches have been inspected, as a faulty door switch can affect the safety interlock system.
