LG Microwave Error Code E-47

E-47 on an LG microwave is an Easy Clean or pH Sensor Door Open Error. It means the microwave detected that the door was opened during an active sensor cooking cycle. The control board logs this error because the automated cooking program cannot continue once the door interrupt occurs. You need to cancel the current mode and restart the cooking cycle from the beginning.

The first step is to press Cancel to exit the current cooking mode, then restart the sensor cooking cycle from the beginning with the door fully closed and latched. If the error reappears without the door being opened, inspect the door latch and hinges for visible damage or misalignment. A failing door interlock switch is the next most likely culprit and would require replacement to resolve the issue.

If the error is simply due to the door being opened mid-cycle, there is no repair cost since canceling and restarting the cycle resolves it. If a door interlock switch needs replacement, parts typically range from $10 to $40 depending on the model, with professional labor adding $75 to $150. A damaged door latch assembly is similarly priced for parts, while a control board replacement is more expensive, generally ranging from $100 to $250 or more for parts alone.

Yes, in most cases canceling the active cooking mode and restarting the cycle from the beginning will clear the E-47 error. If the error persists without the door being opened, unplugging the microwave for a few minutes can reset the control board. However, if the error keeps returning during normal use, a mechanical or electrical component like the door interlock switch may need to be inspected.

When E-47 is displayed, the microwave has halted its cooking cycle and is not operating, so there is no immediate safety hazard from the error itself. However, if the error is caused by a faulty door interlock switch, the microwave should not be used until the switch is repaired, since the door interlock system is a critical safety component. Do not attempt to bypass or disable any door interlock switch.
