If you\u2019re seeing an E5 error code on a Thermador oven, it likely indicates a problem with the potentiometer or selector switch. When these components malfunction, the E5 Thermador range error code is displayed and oven operation is disabled. A failing selector or potentiometer is the most common cause of the E5 error code displayed on a Thermador oven.<\/p>\n

In this guide, we\u2019ll troubleshoot an E5 error display so you can identify and replace a defective oven selector and\/or potentiometer.<\/p>\n

Understanding the function of the oven temperature potentiometer and selector<\/strong><\/h2>\n

Selector switch<\/strong><\/h3>\n

The oven selector, also known as a range selector switch or oven function switch, allows the user to select different cooking functions or modes for the oven such as bake, broil, convection, or self-cleaning. When the user turns the selector switch to a specific cooking mode, it sends signals or activates specific electrical connections within the oven to engage the corresponding heating elements or other features required for that mode. For example, selecting the “bake” mode would activate the baking element, while selecting the “broil” mode would engage the broiler element.<\/p>\n

The oven selector switch often includes various markings or indicators to show the available cooking functions and settings. Its exact design and functionality may vary depending on the specific oven model and manufacturer. Some ovens may incorporate more advanced selector switches with additional features, such as digital displays or programmable settings.<\/p>\n

Potentiometer<\/strong><\/h3>\n

An oven potentiometer, also known as a thermostat or temperature control potentiometer, is a variable resistor with terminals that are used in ovens and other heating appliances to regulate the temperature. It\u2019s typically a temperature control knob or dial that allows the user to set the desired temperature for the desired cooking method.<\/p>\n

The potentiometer is connected to the oven’s heating element or heating system and its resistance changes as the knob is turned, altering the voltage or current supplied to the heating element. Potentiometers work in conjunction with other components, such as temperature sensors and control circuits, to regulate and maintain the oven’s temperature within a range of 170\u00b0F up to about 550\u00b0F.<\/p>\n

Causes of the E5 error display<\/strong><\/h2>\n

When the oven control board detects the resistance from the potentiometer is outside of the expected calibrated ranges for the chosen temperature, an E5 error code is triggered.<\/p>\n

Some potential causes of abnormal or out-of-range resistance from the oven temperature selector include:<\/p>\n
