GE Microwave Error Code ERROR

The ERROR code means the microwave's humidity sensor did not detect food vapor within approximately 2 to 9 minutes during a sensor cooking cycle, so the oven shut itself off. The microwave uses a steam sensor to monitor food doneness, and when no steam signal is registered in time, it stops rather than continue cooking without feedback. Check that your food was covered, at room temperature, and not in a sealed container before assuming the sensor is faulty.

The microwave shuts itself off when ERROR appears, so it will not continue cooking in an unsafe state. You can still use manual time-cook functions on most GE models because those do not rely on the humidity sensor. Avoid using any sensor cook modes until the issue is resolved, as the cycle will terminate early every time.

If the problem is cooking conditions, the fix costs nothing. If the humidity sensor needs replacement, the part typically runs between $20 and $60 depending on the model, and a technician will add 45 to 90 minutes of labor at local shop rates. DIY replacement is feasible for someone comfortable with basic appliance disassembly, but high-voltage capacitors inside microwaves retain a lethal charge even when unplugged, so the capacitor must be discharged before any internal work begins.

Start by running the built-in sensor diagnostic: press and hold pads 7 and 8 simultaneously to trigger the quick test. If the test passes, the sensor is likely fine and the issue is with cooking conditions, use a vented cover over your food and make sure it is not frozen. If the test fails, inspect the sensor area for grease or food debris and clean it gently. A sensor that fails the diagnostic after cleaning will need to be replaced, which is a moderate repair involving disassembly of the microwave cavity.

Opening the door or pressing the Cancel or Clear pad will typically clear the ERROR display. However, the code will return every time you attempt a sensor cook cycle if the underlying issue is not resolved. A power reset by unplugging the microwave for 30 seconds can also clear the display, but it does not fix a faulty sensor.
