The present invention is a device for sealing the door of a self-cleaning combination thermal and microwave oven from microwave energy leakage. The invented device provides in combination a wavelength choke, a conductive gasket and a microwave absorber. The choke and gasket suppress the ISM band radiation and most of the out of band radiation while the microwave absorber suppresses the balance of the out of band radiation which may result by improper door closure. The combination is particularly useful in combination microwave and thermal self-cleaning ovens where high temperatures cause expansion and stress not normally encountered in microwave ovens.
