Oven 150 degrees off
hi . i can help.When the food you're baking is done on top but not on the bottom--or when baking just takes far too long to finish--the bake element may be burned out.
You may get fooled into thinking it's working, because the oven is hot inside. But many electric ovens use the broil element, too, during the preheat and bake cycles. So the food may be getting heated only by the broil element, which causes poor baking results.
If the bake element is burned out, replacing it should solve the problem. Otherwise, you need to further troubleshoot the oven's electrical system to locate the defective wire or component.
When the temperature is consistent but too high or too low, it could be one of several different things. First check to see if the thermostat sensing bulb has come loose from its holder. It could be lying on the floor of the oven or resting on the heating element. This would cause the oven to not heat correctly.
If the thermostat bulb is not dislodged, it's likely that the thermostat or sensor is either mis-calibrated or defective.
Electronic ovens with a digital display use a sensor to monitor oven temperature. To solve temperature problems for these models, you may need to replace the sensor. On some digital-display models, you can calibrate the temperature using the key pad. See your operator's manual for details.
Ovens without a digital display often use a mechanical system for controlling temperature. On many of these units, you can remove the thermostat knob and adjust the knob itself to more accurately represent the actual setting of the thermostat.
If, when you remove the knob, there's a screw on the back of it with a small calibration plate, you can loosen the screw, adjust the plate, then tighten the screw again. If the knob isn't adjustable, and the oven temperature is off by more than 30 to 40 degrees, you need to replace the thermostat to solve the problem.
