The power turns on and the microwave function works, but when the door is opened once, it resets to the initial state. For example, if you open the door while the microwave is heating, you cannot add more heating from that point. Due to the above condition, this item is being sold as junk. Please understand that it may stop heating at any time before purchasing. Two almost unused square plates, a grill net, and the instruction manual are also included. - Brand: HITACHI - Model: MRO-W1A - Color: Black - Function: Oven Range Thank you for viewing.
