Microwave Precaution (Operating Empty)
Do not operate the oven while empty. This can cause damage to the oven or create the possibility of a fire.
If, by accident, the oven should run empty for a minimal amount of time (approx 5 min), no harm is done. Do try to avoid operating the oven empty at all times--it saves energy and prolongs the life of the oven If running the oven empty should occur, it may overheat and shut down. Allow the oven to cool down and reset itself. Try using the oven again normally to make sure it is heating.
If the microwave does not work properly, service will be required. For service, please schedule an appointment with GE Appliances Factory Service.
