Microwave Makes a Popping Noise

If a popping noise is heard in the microwave oven, check the following:

• Popping sounds are usually attributed to the food being cooked. Food with high fat content will pop and sizzle as it heats up. Covering the container will reduce this noise. Food spills will also cause popping.
• Pressure builds up in foods with skin, like potatoes,and then skin can pop. Piercing the skin before cooking will prevent this.
• DO NOT run the oven empty.
• DO NOT leave a cooking probe in microwave unless being used.
• Make sure that the metal cooking rack is firmly in place and not upside down. The rack is used for multi-level cooking only, not single items.
• Use only microwave-safe cookware. 

If the popping noise continues and is not food related, or if the cavity is damaged, we recommend service. For service, please schedule an appointment with GE Appliances Factory Service.
