I have a Maytag electric range that is about 10 years old. I measured the
temperature using a Fluke meter with thermocouple. At 350 F , it fluctuates
+ and - 50 degrees from the setpoint of 350 F (once it is heated up). Since
the oven is not a convection oven, this is probably pretty good behavior.

Yours sounds real bad but it could be due to having something in the oven
that interferes with the hot air coming in contact with the temperature
probe, such as ceramic tile on the bottom for bread baking. A convection
oven should be much better for temperature control since it uses a fan.
