Recently, both hinges on my oven door (John Lewiscooker Mod JLB10S601) 'cracked' The heavy, unsupported door fell to the floor, thus shattering the front glass panel! Unfortunately, my product Warranty expired last year....Is there any way that I could purchase a new oven door to fit myself (according to the manual) and if so, from where? Thank you for your help, L Johnson.
