Thermador Electric Oven Not Heating Up? Here’s Why…

While this high-quality brand is known for its superior function, a Thermador electric oven can still experience heating issues. Wondering, “why won’t my Thermador oven heat up correctly?” A broken bake element may be the cause. Inspect the element for damage that can cause uneven heating or no heat at all. Learn more reasons for a Thermador electric oven not heating up to pinpoint the problem quickly.

Troubleshooting a Thermador
Electric Oven Not Heating Up

While some heating issues can be resolved with a simple adjustment, sometimes a Thermador electric oven not heating up requires a professional repair. Our list of the most common reasons includes the right solutions for faster troubleshooting.

1. Power Supply Problems

Before investigating a malfunction, first check your oven’s power supply. There are several power issues that can result in an electric oven not heating up properly.

Here’s how to assess power supply problems:

  • Check the outlet: Electric ovens require a 240V outlet for adequate power. Make sure the oven is correctly plugged into the right outlet. Multimeter testing may be necessary if you suspect that the outlet isn’t working properly.
  • Look for tripped breakers: Make sure there are no tripped breakers in your home’s circuit breaker box that could cut off power to the oven.
  • Avoid using extension cords: These cords can’t safely transmit the power levels the oven requires.

2. Inaccurate Oven Thermostat

The oven thermostat monitors the internal temperature as it fluctuates, signaling other components to increase or decrease the heat as needed. Sometimes, the thermostat requires adjusting to more accurately sense the internal temperature. In rare cases, the thermostat is faulty and requires replacement.

If you find your Thermador oven isn’t heating to the temperature you set, you may need to adjust the thermostat. Refer to your user manual for the specific adjustment instructions for your model oven.

3. Broken Bake Element

A broken bake element is one of the common self-cleaning oven dangers that can result in a Thermador electric oven not heating up. Located at the bottom of the oven, the bake element’s metal coil contains wires that generate heat when they receive electric current. When functioning properly, the bake element will produce an even, red glow and steady heat.

The high temperature of the self-clean setting can cause damage like holes or blistering on the bake element. When damaged, it may also have an intermittent glow or not glow at all. Even if the self-clean setting wasn’t recently used, a bake element could suffer this damage. If multimeter testing confirms a lack of continuity, the bake element must be replaced.

4. Blown Thermal Fuse

An oven’s thermal fuse is a protective device that will blow if the oven is in danger of overheating. Once it does, power to the oven is cut off, resulting in a Thermador oven not heating up at all. If your oven hasn’t been in danger of overheating, the fuse can also blow if it’s faulty. In either case, a blown fuse can’t be repaired and must be replaced.

5. Faulty Oven Control Board

If all else fails and you still find your oven not getting hot, it’s possible the control board is faulty. This computerized board responds to your commands, as well as signals from other oven components, to adjust heat and turn it on and off. A damaged or faulty board won’t be able to process or transmit these signals, which could result in heating problems.

As this is a more complex repair, we recommend that a professional service assess the control board and replace it if necessary.
