We had a severe storm which resulted in a power outage for about 24 hours. When the power went on, our microwave started to run though numbers on the display screen. 1 2 3 4. It runs through each number about 4 times until it stops on 1. Update (07/24/2016) It’s a Kenmore model number 721.80032700.
Sometimes shutting off the circuit breaker that the microwave oven is connected to for 30 seconds will clear the fault, error or function code; however, there are some cases when further service may be required. http://products.geappliances.com/applian…
