Samsung Microwave Error Code error1

The error1 code on a Samsung microwave means the appliance has detected a shorted circuit in the internal sensor system. This sensor monitors the oven cavity during cooking cycles. The microwave disables itself when this fault is detected to protect internal components from potential damage caused by the abnormal electrical condition.

No, you should not attempt to use the microwave while error1 is active. The unit will typically prevent operation on its own, but attempting to bypass this fault and run the microwave with a shorted sensor circuit could result in improper cooking performance or further component damage. Resolve the fault before resuming use.

If the issue is simply contamination on the sensor connector, the repair may cost nothing beyond your time. Replacing a faulty humidity or temperature sensor typically runs in the range of $20 to $60 for the part, plus labor if a technician is involved. If the control board is at fault, board replacement costs can range from $80 to $200 or more depending on the model, which may make replacement of the appliance worth considering.

In many cases, yes. Start by letting the microwave cool for at least 5 minutes, then check whether the error clears. If it does not, inspect the sensor connector for contamination such as food residue or moisture and clean it carefully. If the sensor wiring or the sensor itself is visibly damaged, those components will need to be replaced, which requires basic disassembly of the unit.

A reset by unplugging the unit for a minute or two may temporarily clear the display, but if the underlying short condition still exists, the error will return as soon as the microwave attempts to use the sensor. A lasting fix requires identifying and correcting the cause of the short, whether that is contamination, damaged wiring, or a failed sensor.
