⚠️ JennAir Wall Oven Not Heating, Showing Error Codes, or Display Dead? W10821712 Is the Fix.
The electronic control board is the brain of your JennAir wall oven — it manages temperature regulation, bake and broil element cycling, convection fan control, and the user interface. When it fails, your oven may not heat, display error codes, have unresponsive controls, or shut off unexpectedly mid-cook. Part W10821712 is the genuine OEM replacement control board, directly superseding W10635086.
This is the main electronic control board — the primary logic board governing all oven functions. If your oven is unresponsive, not reaching temperature, or displaying fault codes that persist after a power reset, this board is the primary suspect. Control boards are model-specific — confirm your full model number before ordering.

Skill Level: Intermediate–Advanced. Disconnect power at the breaker before beginning — this board carries line voltage. The control board is located behind the oven’s control panel. Remove the panel screws and carefully photograph all wire harness connections before disconnecting. The board is static-sensitive — avoid touching circuit traces and work on a non-static surface. Transfer all connectors to the new board in the exact same positions. Restore power and run a test cycle to confirm full operation.

A faulty oven temperature sensor (RTD probe) can cause the exact same symptoms as a failed control board — oven not heating, error codes, or temperature that won’t stabilize. The sensor costs a fraction of the board and takes 10 minutes to swap. Test it with a multimeter first: at room temperature it should read approximately 1080Ω. If it’s open or out of range, replace the sensor before committing to the control board. Search your model number + “temperature sensor” to find the right one.
