Hi, I just bought a used Kenmore that did not come with a user manual. The model # is 6303190 Which I cannot find a manual for on your website. Currently my elements are both not working in the oven, but the stove top is functioning fine. As new elements are fairly expensive, I wanted to ask if there could be a fuse problem, and if so, where would you locate them to check before purchasing new elements. Thank you very much for your time.
