Steam and vapor from around the door while cooking is normal. This does not mean that the unit is leaking microwave energy. The door is designed to allow heat and steam to escape to prevent the overheating of the unit.
Condensation inside the unit is normal when cooking foods of high moisture content. It is also normal to see some condensation between the door panels, unless the condensation does not dissipate within a reasonable amount of time. Moisture should dissipate in ten to fifteen minutes. Allow the door to stand open for approximately 15 minutes to accelerate the dissipation of the moisture.
If the moisture does not evaporate in a reasonable amount of time, we recommend service. If you continue to have problems, please contact Haier Appliances at 1-877-337-3639 or visit https://www.haierappliances.com/support/schedule-service to arrange service.
