Hello - I have a Frigidaire GLGFS66.ABB gas range/oven. When closing the oven door, it operates smoothly from the horizontal (fully open) position up to the broil stop position, but requires excessive force to get past the broil stop position. I'm not sure if the hinges need to be replaced or if it's a lubrication issue (or something else) causing the jam. A pair of hinges is roughly $100 so I don't want to replace if something else is causing the problem. Please advise. Thanks
