KitchenAid Oven Error Code E0

Temperature sensor opened.

KitchenAid codesKitchenAid oven codes

Temperature sensor opened.

First step from the service manual

Check sensor connection. Measure sensor resistance (1080 ohms at 70°F. Add 2 ohms per degree). If resistance is not valid, replace sensor.

What E0 means on a KitchenAid oven

Error code E0 on a KitchenAid oven indicates that the oven temperature sensor circuit has opened, meaning the control board is detecting an infinite or out-of-range resistance reading from the temperature sensor. The temperature sensor, also called an RTD (resistance temperature detector), is a probe mounted inside the oven cavity that continuously sends resistance readings to the control board. The board uses these readings to regulate heating elements and maintain accurate oven temperature. When the circuit opens, the board loses all temperature feedback and triggers E0 to prevent unsafe operation.

The sensor operates on a predictable resistance curve: at 70 degrees Fahrenheit, the sensor should measure approximately 1080 ohms, increasing by roughly 2 ohms for every degree of temperature rise. Any reading that falls outside this expected range, or a completely open circuit reading, will cause the control board to flag E0. This makes resistance measurement at the sensor connector a critical first diagnostic step before replacing any components.

The most common causes of an open sensor circuit include a failed sensor element, damaged wiring between the sensor and the control board, or a loose or corroded connector. Physical damage to the sensor probe itself, such as cracking from thermal stress or impact, can also cause the internal element to break. Because the control board cannot safely operate the oven without valid temperature feedback, the oven will not heat while E0 is active.

Common causes of E0

  1. 01

    Failed temperature sensor

    Part replacement

    The sensor element inside the probe has broken open internally, causing an infinite resistance reading. Confirm by measuring resistance at the sensor connector; a reading far outside the 1080-ohm baseline at 70 degrees Fahrenheit indicates a failed sensor.

  2. 02

    Loose or disconnected sensor connector

    Wiring / connection

    The wire harness connector at the sensor or control board end may have worked loose over time from vibration or heat cycling. Inspect both ends of the sensor wiring for fully seated, locked connectors.

  3. 03

    Damaged sensor wiring

    Part replacement

    The wires running from the sensor through the oven cavity can crack, fray, or burn through due to heat exposure. Visually inspect the full length of the sensor wiring harness for breaks, melted insulation, or pinched sections.

  4. 04

    Corroded sensor or connector terminals

    Wiring / connection

    Moisture or grease contamination can corrode the sensor connector terminals, increasing resistance enough to register as an open circuit. Check terminals for discoloration, pitting, or oxidation and clean or replace as needed.

  5. 05

    Faulty control board

    Part replacement

    If the sensor and all wiring check out within spec, the control board input circuit for the sensor may have failed. This is the least likely cause and should only be considered after confirming the sensor reads the correct resistance.

Frequently asked questions about E0

What does E0 mean on a KitchenAid oven?
E0 on a KitchenAid oven means the temperature sensor circuit has opened, so the control board cannot receive a valid resistance reading from the oven temperature probe. The sensor should measure approximately 1080 ohms at 70 degrees Fahrenheit. Because the oven cannot monitor its internal temperature, it shuts down heating as a safety precaution and displays E0.
Can I fix E0 on my KitchenAid oven myself?
Yes, in many cases this is a DIY-friendly repair. Start by checking the sensor connector for a loose or corroded connection, which costs nothing to address. If the connector is secure, use a multimeter to measure sensor resistance and compare it to the expected value of 1080 ohms at 70 degrees Fahrenheit. If the reading is out of range, replacing the temperature sensor is a straightforward repair that typically involves removing two screws and a wire connector inside the oven cavity.
Is it safe to use my KitchenAid oven while E0 is displayed?
No, you should not attempt to use the oven while E0 is active. The oven cannot regulate its temperature without a functioning sensor, which means heating elements could run unchecked. The oven's control board intentionally disables heating when E0 is present to prevent this situation.
How much does it cost to repair a KitchenAid oven showing E0?
If the fix is simply reseating a loose connector, there is no parts cost involved. A replacement temperature sensor typically costs between $20 and $60 depending on the model. If a professional technician is needed, expect to pay between $100 and $250 in total for a service call plus parts, depending on your location and the service provider.
Will resetting my KitchenAid oven clear the E0 error code?
A reset may temporarily clear the E0 code, but the error will return as soon as the control board checks the sensor circuit again if the underlying problem has not been fixed. Resetting the oven by cutting power at the breaker for a few minutes is useful for ruling out a control board glitch, but a persistent E0 code requires inspecting and testing the sensor and its wiring.
