I have inherited a lovely 1950's Frigidaire Electric stove. It has a warmer on the left side and an oven on the right with the option of running 2 different oven temperatures. The range works great...even has an option of a deep fryer. My problem is only the bottom oven will work and if I remove the top 2 elements of the upper oven and stick them into the bottom (in order to create a single larger stove) nothing works. I have tried changing the fuses to no avail. Any advice greatly appreciated.
