The oven door on this Gaffer and Sattler gas stove does not close all the way; it remains open about 1/2 inch. I can see part of the oven door springs, and they look newish, shiny bright, and the stove is quite old. I wonder if they have been replaced, but by springs that are too weak. To replace them, do I have to take the sides off the stove? Is there another possible cause for the oven door not closing? It seems to be straight.
