It sounds like you have a bad temperature sensor. Some can be calibrated, but not by a hundred degrees.

Hi,
If your electric oven is not heating then you probably have a bad heating element in your oven. This is not that hard to fix yourself...
Check out this tip that I wrote about the Oven not heating problem..

You may have 2 problems.
One. The temperature sensor could be bad. You can remove the temperature sensor and check it with a ohm meter. It should read 1050 to 1150 ohms. If not. It is bad.
Two. The glowbar ignitor could be bad and not igniting the gas safety valve.Open the bottom drawer of the oven and set the oven to bake. The burner should light in 60 seconds or less. Re-light should be about 30 seconds or less.
If it takes longer the ignitor is bad.

REPLACE HEAT SENSOR

if you cant program it for more than the 270 you may have changed it from farienhiet ( bad spelling) to celcius. pushing and holding broil may switch it back.

Replace the oven temperature sensor part # wb20k0004

I have the exact problem. We had the ignitor replaced 2 already and it works for 18 months and stops. Occasionally, it the oven won't even start to heat. I am ready to throw it out.
