I am having a problem with the oven temperature. Lots of times it is between 35 and 50 degrees under the desired temperature. The Wiring Diagram in the back of the oven says that the flames at the bottom of the oven should be 1 inch long. I opened the bottom of the oven and it is hard to tell because they are not shooting out like the broiler flames do. The flames for the oven are curling up around the pipe.

The Wiring Diagram also says that I can perform and oven temperature calibration by pressing both the Hour up and down buttons. It says that it should say 00. For some reason mine said 35.

I already replaced the thermostat in the oven and it didn't help.
