What does the F4 error code mean?<\/strong><\/h2>\n

The F4 error code usually indicates that there\u2019s a problem with the humidity sensor in the microwave. Specifically, it means the control board is no longer detecting the humidity sensor signal during an active cooking cycle.<\/p>\n

The humidity sensor does what its name suggests: it monitors steam and humidity levels inside the cavity as food cooks. When it\u2019s working correctly, it provides continuous feedback to the control board. Loss of this sensor\u2019s signal mid-cycle can cause the F4 error.<\/p>\n

The humidity sensor is a small plastic part that protrudes into the oven cavity. It connects back to the main control board via a wire harness.<\/p>\n
