Before you start
- Find your model number. It's on the rating label, usually inside the door or lid, on the frame, or on the back or side panel.
- Try a reset. Unplug the appliance or switch off its breaker for 10 minutes. Many codes are one-off glitches.
- Stay safe. Never bypass safety switches or work on live wiring, gas or refrigerant lines. Each guide tells you when to call a technician.
