Fix KitchenAid Oven Little to No Heat When Baking

The bake element — the number-one cause#

The bake element is the U- or W-shaped element at the bottom of the cavity, and when it fails the oven makes no heat from below on Bake (the top broil element may still work, which is why some owners say it heats on broil but not bake). Set Bake to 350 degrees F, open the door after 2 to 3 minutes, and look — it should glow red-orange; no glow means a failed element, which a continuity test confirms (an open circuit is burned out). On premium models the bake element is concealed under the floor, so you test it at the wire connections behind the oven.

Sensor, convection element, and board#

• Temperature-sensor drift. The RTD at the top-rear reads about 1,080 ohms at room temperature (within about 50 ohms), rising as it heats; if it drifts the board miscalculates and under- or overheats. Before replacing it, check the temperature-offset calibration in Settings (hold Bake for 5 seconds on many models) and confirm it's at zero, since a previous offset can explain under-heating.
• Even-Heat convection element failure. The bow-tie element behind the rear fan drives Convection Bake and Roast; if it fails, the fan still runs but the rear puts out no heat, so those modes don't heat properly while standard bake may still give some from below.
• A control-board relay. The board uses a relay to switch 240 volts to the bake element; if that relay fails open, no power reaches the element even though the display shows the oven heating. If the element has continuity but gets no voltage on Bake, the relay is the suspect.

The voltage check#

KitchenAid electric ovens need full 240 volts on a dedicated 40-amp or 50-amp circuit. If one leg drops out — a tripped breaker pole, a loose terminal, or a failed wire — the oven runs on 120 volts, and at half voltage the element makes only about 25% of its rated heat, so the oven warms but never reaches temperature. Measure at the outlet or terminal block: it should read 240 volts across the two hot legs, and 120 volts means a single-leg failure.

EasyConvect and a holiday note#

Remember EasyConvect automatically drops the temperature about 25 degrees F in convection, so Convection Bake set to 350 degrees F actually runs near 325 — that's by design, not a fault. With holiday baking coming, confirm the bake element glows and the voltage is a full 240 before the big day. A single element, sensor, or relay on a KitchenAid under 8 to 10 years old is well worth repairing — book an EasyBear technician, and stop if you smell burning or see sparking.
