I have had Euro-Pro Oven that I bought long time ago. I do not have Manual and also do not see Model or Label around this unit. Any way, inside the oven there is a white square plate heater that put on the top 2 heater coil sticks cross side by side. I would like to order a square heater plate that was broken 2 pieces. Could you tell me how much that piece cost. Thanks and you have a wonderful evening. Le
