Everything works fine except it does not heat up
Hello there:
Here are two instances of when food "bakes poorly:" or not at all
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.
