Jenn-Air Oven Error Code F33

F33 means the control board has detected a failure in the meat probe circuit, either at the Meat Probe Jack inside the oven cavity or in the meat probe itself. The board monitors this circuit for resistance values within a specific range and triggers F33 when the reading is out of range or absent entirely. This can occur even when you are not actively using the probe.

In many cases the oven will still operate for standard baking and broiling while F33 is active, since the meat probe circuit is separate from the main heating functions. However, the meat probe feature will not work correctly, and you should not rely on it for food temperature monitoring until the fault is resolved. Check your specific model's behavior, as some control boards may restrict certain functions when a fault code is active.

Clearing the code by cycling power to the oven may temporarily clear the display, but F33 will return if the underlying fault in the meat probe or Meat Probe Jack is still present. A persistent F33 after power cycling confirms there is a real electrical fault in the probe circuit that requires physical inspection and testing to resolve.

Start by unplugging the oven and removing the meat probe from the jack if it is connected. Inspect both the probe tip and the jack contacts for corrosion, debris, or physical damage. Use a multimeter to measure the resistance of the meat probe across its two terminals and compare the reading to the specification in your service manual, typically around 1000 ohms at room temperature for a standard NTC probe. If the probe reads open, shorted, or significantly out of range, replace the probe. If the probe tests good, inspect the jack and wiring harness for damage before considering control board replacement.

If the meat probe is the cause, a replacement probe typically costs between $20 and $60 depending on the model, and it is a simple plug-in replacement requiring no tools. A replacement meat probe jack costs roughly $30 to $80 in parts, but replacing it requires disassembling part of the oven cavity and is more involved. If the control board has failed, parts alone can run $150 to $400 or more, and professional labor adds to the total. Diagnosing the fault correctly before ordering parts will save significant cost.
