Hey, My Frigidaire electric range (model CFEF366EM -- about 2 years old) will not heat properly. I will set the temperature to the desired 300, 350 etc and the oven only heats up to about 200. Everything else is working fine. Both the top and bottom elements emit some heat but not nearly what it should be. I am not even sure what to start testing/replacing/checking. Any advice would be much appreciated Thanks!
