KitchenAid Oven Error Code E1

E1 on a KitchenAid oven means the control board has detected a short circuit condition in the oven temperature sensor circuit. The sensor should measure around 1080 ohms at 70°F and increase by 2 ohms per degree. A reading outside the expected range triggers this fault. It can also appear if the oven overheated due to a welded relay holding the heating element on continuously.

No, you should not continue using the oven while E1 is active. If a relay has welded closed, the oven has no way to regulate temperature and can reach dangerously high heat levels, creating a fire hazard. Stop using the oven and unplug it or shut off the circuit breaker until the fault has been properly diagnosed and repaired.

Repair costs vary depending on the root cause. A replacement temperature sensor typically runs in the range of $20 to $60 for the part alone. If a control board replacement is needed due to a welded relay or board failure, parts can range from $100 to $300 or more. Adding professional labor generally brings total repair costs to between $150 and $400 depending on the fault and your location.

If the cause is a disconnected or loose sensor connector, reseating it is a straightforward DIY repair. If the sensor itself has failed, replacing it requires basic tools and is manageable for a confident DIYer. However, if the issue involves a welded relay on the control board, that repair involves handling high-voltage components and is best left to a qualified technician.

Resetting the oven by cutting power may temporarily clear the E1 code, but if the underlying cause is a shorted sensor or a welded relay, the code will return once the oven is used again. A reset does not fix the hardware fault. Proper diagnosis with a multimeter to check sensor resistance is necessary to determine whether a repair is needed.
