Why does my built-in oven not heat up to the temperature that it was set at?

This oven is a Kenmore wall oven model 911.4012990. When the bake button is pressed and the temperature is set to say, 350 degrees, (this is starting with a cold oven!). The display will then drop to 300 degrees in a few seconds, instead of 100 like it normally does with a cold oven! The temperature will then increase in 5 degree increments (as it used to) but, these occur much faster until the display reaches 350.
The actual oven temperature is not anywhere close to 350! (significantly lower). Is this a faulty thermostat, or sensor?

I would test the resistance of the oven temperature sensor probe first. The oven temperature sensor probe is located inside the oven cavity in the rear upper left hand corner or possibly in the rear upper right hand corner. It can be taken out and tested using an OHM meter. The oven temperature sensor should have a resistance measurement of 1100 ohms at room temperature. If the sensor measures approximately 1100 ohms, the oven control board will need to be replaced. If it does not measure 1100 ohms, replace the oven sensor. The

oven sensor

is part #WB21X5301 at the cost of $73.49

The oven control board is no longer available for ordering. The only way to get a working control board is to have a Sears technician remove the control and send if off for rebuilding. It will cost $130.00 to have a technician come out and service the range plus the cost of the control board.

It would not be cost effective to have the control board removed and rebuilt. I recommend replacing the wall oven rather than having the control board rebuilt.
