Thermador oven not heating

Is Your Thermador Oven Not Heating? This May Be Why…

A high-end Thermador oven provides superior cooking power but that doesn’t mean it’s exempt from common heating issues. Why won’t my Thermador oven heat up? The thermostat may need adjusting to monitor the internal temperature. Learn common reasons for a Thermador oven not heating so you can quickly solve the problem.

5 Reasons For a Thermador Oven Not Heating

A Thermador oven not heating may have a part failure but, sometimes, a simple adjustment can solve the problem. We’ll troubleshoot the most common causes of heating problems and specify the right solution.

Thermador oven isn't heating

Oven Thermostat Needs Adjustment

Both gas and electric ovens have a thermostat that monitors the oven’s set temperature, signaling for more or less heat to maintain it. If your Thermador oven isn’t heating to your expectations, it’s possible the thermostat needs adjusting to maintain your temperature settings. While the thermostat may also be faulty, this rare occurrence isn’t likely.

Refer to your Thermador user manual to determine how to adjust the thermostat on your model oven. It can typically be adjusted in 5-degree increments to better reflect your cooking and timing preferences.

Thermador Oven Power Issue

Sometimes a power issue, not an oven problem, maybe the reason for an oven not getting hot. Even gas ovens require electricity to ignite and power the control panel.

Here’s how to make sure your oven is receiving sufficient power:

  • Check the power cord: Make sure it’s damage-free and fully plugged in.
  • Test the outlet: Use a multimeter to make sure the outlet is delivering the proper voltage.
  • Avoid extension cords: These cords can’t reliably transmit the voltage an oven requires, resulting in surges that interrupt power.
  • Look for tripped breakers or blown fuses: Check your home electrical panel, replacing blown fuses or resetting tripped breakers.

Burnt Out Bake Element

Electric ovens get their heat from two heating elements at the top and bottom of the oven. When the wiring in each element receives electrical current, it produces heat and the element glows with a steady, red hue. If you notice your Thermador oven not heating evenly, with food remaining underdone on the bottom, the bake element may be burnt out. Other visual signs include blistering, breakage, or dark spots on the element itself.

Multimeter testing of the bake element can confirm that it’s burnt out by showing a lack of continuity. In this case, the bake element must be professionally replaced.

Thermal Fuse is Blown

Is your oven not heating up at all? It’s possible the thermal fuse has blown. This valve acts as a safety device and will blow if the oven is in danger of overheating. However, more commonly, the fuse will blow if it’s faulty. Once the fuse has blown, the oven won’t be able to heat up at all.

Confirm that the fuse has blown by testing it with a multimeter. If it shows no continuity, it can’t be repaired and must be replaced.

Faulty Thermador Oven Control Board

If the above reasons aren’t responsible for your oven’s heating issue, it’s possible that the oven control board is faulty. This computerized board governs all oven operations, responding to your control panel commands and sending voltage to the appropriate function. If the control board is faulty, it won’t respond to commands and the oven won’t heat up. 

A faulty control board can’t be repaired and, given its complexity, should be replaced by a professional oven repair service.
