Oven Won't Heat or Bake? Surface Element 00445258 – Fix No Heat & Bake Failure Fast

If your Bosch oven won't heat, fails to bake, or produces uneven cooking results, a failed oven surface (bake) element is the most common cause. In most Bosch wall ovens and ranges, the surface bake element is the primary lower heating element that generates heat for baking and roasting. When it fails — due to a burned-out coil, cracked element, or open circuit — the oven will not reach temperature or will heat unevenly. ⚡ Common failure point in Bosch-built ovens — especially in units over 7 years old or after a power surge. Part 00445258 is the genuine OEM Bosch replacement bake element that restores full oven heating performance and even temperature distribution.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Oven has power — display, clock, and broil element work normally
• ✔ Oven temperature sensor (RTD probe) has been tested and reads ~1100Ω at room temp
• ✔ Oven control board has been ruled out — no error codes displayed
• ✔ ONLY problem is oven won't heat on bake, won't reach set temperature, or heats unevenly from the bottom

Not sure? Send us your model number — we'll confirm before you order.

🔧 Common Symptoms

• Oven won't heat on Bake — broil still works
• Oven takes much longer than normal to reach temperature
• Food burns on top but is undercooked on the bottom
• Visible burn marks, cracks, or blistering on the lower element
• Oven trips breaker when Bake is selected
• Element glows red in one spot only — not evenly across the full coil

✔ If these symptoms match, this is the most likely failed component in the system.

✔ In most cases, replacing this bake element restores full oven heating performance immediately.
