What F33 means on a Jenn-Air oven

The F33 error code indicates the Jenn-Air oven control board has detected a fault in the meat probe circuit. Specifically, the board is reading a resistance value from the Meat Probe Jack or the Meat Probe itself that falls outside the acceptable range, or it is detecting no signal at all. This typically points to an open or short circuit in the probe, the jack receptacle mounted inside the oven cavity, or the wiring connecting the two to the control board. Diagnosing this code starts with measuring resistance values at both the probe and the jack.

For homeowners, the meat probe is the temperature sensor you plug into the oven wall to monitor the internal temperature of roasts and other large cuts. The jack is the small port inside the oven cavity where the probe plugs in. When the F33 code appears, the oven's control board cannot get a reliable reading from this circuit. This can happen even if you are not currently using the probe, because the control board continuously monitors the jack. The probe or the jack may be damaged, corroded, or have a loose connection that is disrupting the signal.

In many cases, this is a repair homeowners can handle by testing the probe with a multimeter and replacing it if the resistance is out of spec. If the probe tests correctly but the code persists, the jack or associated wiring becomes the next target.

Common causes of F33

  1. 01

    Damaged or failed meat probe

    Part replacement

    The meat probe itself is the most frequent cause of F33. Internal wire breaks, damaged sensor tips, or corrosion from repeated heat cycles can cause the probe to read outside the expected resistance range or produce no signal.

  2. 02

    Corroded or damaged meat probe jack

    Part replacement

    The jack receptacle inside the oven cavity is exposed to grease, moisture, and high heat over time. Corrosion or physical damage to the jack's contacts will disrupt the circuit and trigger F33 even when a functional probe is connected.

  3. 03

    Loose or broken wiring between the jack and control board

    Wiring / connection

    The wiring harness running from the meat probe jack to the control board can develop loose connectors, pinched wires, or breaks. This interrupts the signal path and registers as a probe circuit fault.

  4. 04

    Failed control board

    Part replacement

    If the meat probe and jack both test within correct resistance specifications and all wiring connections are secure, the control board itself may have failed and is misreading or no longer processing the probe circuit signal.

Frequently asked questions about F33

What does the F33 error code mean on a Jenn-Air oven?
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.
How do I fix the F33 code on my Jenn-Air oven?
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.
Can I still use my Jenn-Air oven when the F33 code is showing?
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.
How much does it cost to fix the F33 error on a Jenn-Air oven?
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.
Will clearing the F33 code and restarting the oven fix the problem?
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.
