LG Microwave Error Code E-14

E-14 on an LG microwave indicates a gas sensor dry-up or no-load error. It means the microwave's internal gas or humidity sensor did not detect any moisture or gases during operation, which happens when the cavity is empty or the food inside is too dry. The microwave halts operation and displays the code as a protective measure. Placing food with adequate moisture inside and restarting the unit is the recommended first step.

Yes, it is generally safe to resume use after correcting the root cause, which is usually operating the unit without food. The E-14 code is a protective fault designed to prevent the microwave from running under a no-load condition, which can stress internal components. Once food is placed inside and the error is cleared, normal operation can continue.

If the cause is simply an empty cavity, there is no repair cost at all. If the gas sensor has failed and needs replacement, parts and labor costs can range from roughly 80 dollars to 200 dollars or more depending on the specific model and labor rates in your area. Checking wiring connections first is a no-cost diagnostic step that should be completed before purchasing any parts.

Start by placing a food item with normal moisture content in the cavity and restarting the microwave. If the error clears, no further action is needed. If E-14 returns even with typical food loads, inspect the gas sensor wiring for loose or corroded connections, and consider testing or replacing the gas sensor itself if the wiring checks out.

A reset alone may temporarily clear the display, but the error will return if the underlying condition is not resolved. The correct approach is to insert food with sufficient moisture content before restarting. If a sensor or wiring fault is causing E-14, a simple reset will not provide a lasting fix and component-level diagnosis will be needed.
