A:Answer Hello iowawalilley,
Great question! We'd be more than happy to help you. Your microwave having vents at the top, means that it's externally vented. External ventilation uses a fan to draw air through the microwave's vents and into an exhaust duct leading to the outside. This means that most of the moisture, heat, and odor generated by cooking goes directly outside. To find this information, we recommend looking at the specs of the microwaves you're considering. Check the row that says "venting type", and make sure it says externally vented. We would like to know more about your current microwaves measurements. This would allow us to be more accurate in suggesting compatible replacements. You can reach out to us through the support link on our website or on social media. We thank you for choosing GE and hope to hear from you soon!
