OH NO! Sorry to hear that.I have been there a few times,in fact my oven is broken right now.I can say that there are a couple of methods fixing this problem.You should be able to get a service man to check it out and possibly order a part and fix it,when I did this and it was a starter for a gas oven it was roughly $70.00.Another option is to look at possible used or surplus ovens that have been refurbished,Brand new ones have a reasonable price tag if you shop around and you can get the warranty but that means no baked goods for a few days.

be carefull about the intensity as you dont want to over do it to fast.Once its all dialed in you will have the quality and quantity of light for whatever you want.That turbinaria sure looks radiant.
