Jenn-Air Oven Error Code 3d51

Error code 3d51 means the meat probe calibration value stored in the UH1/2 control board is out of the accepted range. When this happens, the control board disables all probe functions to prevent inaccurate temperature readings. This code applies specifically to Jenn-Air ovens equipped with the UH1/2 control module. The fault is almost always traced to the control board rather than the probe or its wiring.

The 3d51 code only disables the meat probe functions, not the oven's bake or broil operations. Standard cooking modes should remain available. However, you will not be able to rely on the probe for monitoring internal food temperatures until the issue is resolved, so use an independent thermometer as a substitute in the meantime.

A power reset may clear the code if the calibration data was lost due to a temporary power disruption and the board can successfully reinitialize. Disconnect the oven from power for a few minutes before restoring it. If the code returns after the reset, the control board has a recurring fault with storing or validating calibration data and will likely need to be replaced.

You can start by performing a hard reset: disconnect the oven from power for several minutes, then restore power and see if the error clears. If the control board can reinitialize its calibration data successfully, the code may not return. However, if 3d51 comes back after the reset, the control board likely has a persistent memory or hardware fault that requires replacement.

If the issue requires a control board replacement, parts alone typically range from $150 to $400 depending on the specific model, and professional labor can add another $100 to $200. If a simple power reset resolves the issue, there is no parts cost involved. Getting a diagnosis from a qualified technician before ordering parts is recommended.
