Thermador or Bosch Oven Not Heating After Overheat Event? Thermal Fuse 00414633 – Fix Dead Oven Fast
An oven that suddenly stops heating — especially after running hot or a self-clean cycle — is almost always a blown thermal fuse. In most Thermador and Bosch wall ovens and ranges, the thermal fuse is a one-time safety device that permanently opens the circuit when the oven exceeds a safe temperature threshold. When it blows, the oven goes completely dead — no heat, no bake, no broil — even though the control board and other components are fine. ⚡ Common failure point in Thermador and Bosch-built ovens, especially after self-clean cycles. Part 00414633 is the genuine OEM thermal fuse that restores full oven operation by replacing the blown safety cutout.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Oven powers on — display and controls respond normally
- ✔ Oven ran a self-clean cycle or overheated before the failure
- ✔ Bake element and broil element test good (continuity confirmed)
- ✔ ONLY problem is oven produces zero heat — no bake, no broil

🔧 Common Symptoms
- Oven completely dead — no heat on bake or broil after self-clean cycle
- Oven display and controls work normally but oven never heats
- Oven stopped heating suddenly with no error code or warning
- Oven ran extremely hot or smelled of burning before heat loss
- Bake and broil elements test good but oven still won't heat
- Oven worked fine then went cold — no gradual decline, just stopped
✔ If these symptoms match, the thermal fuse is the most likely failed component in the system.
✔ In most cases, replacing this thermal fuse restores full oven heating immediately.

A thermal fuse blows because the oven overheated — replacing the fuse alone without finding the root cause means it will likely blow again. While the oven is open, inspect the oven temperature sensor (RTD probe) for resistance drift and check the control board for signs of relay failure or burn marks. If the self-clean cycle triggered the failure, the door lock mechanism and thermostat should also be inspected before closing up.
⚙️ Installation
Skill Level: MODERATE — 20–45 minutes. Disconnect power at the breaker before servicing. The thermal fuse is typically located on the back wall of the oven cavity or behind the rear access panel — remove the oven from the wall or pull the range away to access the rear. Disconnect the two wiring terminals, remove the fuse from its bracket, install the new 00414633 fuse, reconnect the terminals, and restore power. Run a bake cycle to confirm full heat restoration before reinstalling the oven.

💡 Pro Tip
A thermal fuse is a symptom fix, not a root cause fix. Before reassembling, test the oven temperature sensor resistance at room temperature — a good Thermador RTD sensor reads approximately 1,080–1,090 ohms. A drifted or open sensor causes the control board to overheat the oven, which blows the fuse again. If the sensor reads out of spec, order it alongside the fuse. Replacing both in one service call saves a second disassembly and a second labour charge.
