Uneven baking is one of the most common calls on any wall oven, and with the HBL8454UC the answer is sometimes sitting right inside the cavity. This 800 Series 30 inch model has Air Fry among its modes, a 4.6 cubic foot space, 4,800 watts, and both Home Connect and a door that closes softly.
The cavity walls are enameled steel and the side racks slot into small dimples in them. When a rack goes back into the wrong dimple, it ends up tilted, and so does everything sitting on it. It sounds too simple to matter, yet it explains a surprising number of bake complaints.
After the racks, we look at the usual aging items: grease from Air Fry reaching the fan and the plate behind it, and a temperature sensor that has drifted over the years. When the oven runs a little cool but the sensor tests fine, we can dial in the offset. A sensor that has itself wandered off is better replaced than worked around indefinitely.
Check that both side racks sit in matching dimples on the cavity walls. A rack a notch out of position tilts everything on it, and this simple slip explains many uneven-bake calls.
Yes, the temperature offset can be changed, and we will do so when the sensor tests healthy. If the sensor has drifted, a new sensor is a better route than living with the correction forever.
Yes, grease can reach the convection fan and the baffle behind it, so planning an occasional cleaning of that area is sensible for anyone who air-fries often.
