What F33 means on a KitchenAid oven

The F33 error code on a KitchenAid oven indicates a fault detected in the meat probe circuit, which includes the probe itself and the probe jack mounted inside the oven cavity. The control board monitors the resistance of the probe circuit through connector pins P3-3 and P3-4. Under normal operating conditions, a properly functioning meat probe will read between 9876 and 10075 ohms at room temperature. When the measured resistance falls outside this window, either too high or too low, the control interprets the reading as a failed component and triggers the F33 fault.

The most common source of this fault is a damaged or faulty meat probe. The thin coiled cable connecting the probe tip to the plug is vulnerable to damage from oven door pinching, heat exposure, or physical stress during storage. The probe jack inside the oven cavity is also a frequent failure point, since repeated plug-and-unplug cycles combined with high heat can cause corrosion, cracked solder joints, or broken internal contacts. A probe left plugged in during a self-clean cycle is a particularly common cause of both probe and jack damage.

Diagnosis begins with disconnecting the meat probe from the jack and inspecting both components visually. If the probe is not connected and the fault still appears, the jack itself or the wiring harness back to the control board is likely at fault. Measuring resistance across P3-3 and P3-4 at the control board connector will confirm whether the reading is within the 9876 to 10075 ohm specification, helping to isolate whether the probe, the jack, or the board is responsible for the out-of-range signal.

Common causes of F33

  1. 01

    Damaged meat probe

    Part replacement

    The probe cable or tip has been bent, pinched, or exposed to excessive heat, causing the resistance to fall outside the required 9876 to 10075 ohm range. Inspect the cable along its entire length for kinks, burn marks, or breaks.

  2. 02

    Meat probe left plugged in during self-clean

    Part replacement

    Running a self-clean cycle with the probe still inserted in the jack exposes the probe and jack to temperatures that can permanently damage both components. This is one of the most common reasons both parts fail simultaneously.

  3. 03

    Corroded or damaged probe jack

    Part replacement

    The jack mounted inside the oven cavity can develop corrosion, cracked contacts, or broken solder connections from repeated use and heat cycling. If resistance measured at P3-3 to P3-4 is out of spec even with a known-good probe connected, the jack is the likely culprit.

  4. 04

    Probe not fully seated in the jack

    Wiring / connection

    A probe that is partially inserted or loosely connected will produce an irregular resistance reading and trigger the F33 code. Remove and firmly reseat the probe before pursuing further diagnostics.

  5. 05

    Faulty wiring harness between jack and control board

    Part replacement

    If both the probe and the jack test as functional but the fault persists, the wiring between the jack and the control board connector at P3-3 and P3-4 may have an open or short. Check for damaged insulation, loose connectors, or broken wires in this section of the harness.

Frequently asked questions about F33

What does F33 mean on a KitchenAid oven?
F33 indicates that the oven control board has detected a fault in the meat probe circuit. This includes the probe itself and the probe jack inside the oven cavity. The control checks for a resistance reading between 9876 and 10075 ohms at the probe circuit connector, and any reading outside that range triggers the code. The fault can originate from a damaged probe, a failed jack, or a wiring issue.
Can I fix the F33 error on my KitchenAid oven myself?
In many cases, yes. Start by unplugging the meat probe from the jack and checking whether the error clears. If the probe cable shows visible damage, replacing it is a straightforward repair. If the jack itself is faulty, replacement requires accessing the oven cavity interior and may involve soldering or wiring work, which is manageable for someone with appliance repair experience. Measuring resistance at the control board connector will help confirm which component needs to be replaced before ordering parts.
Is it safe to use my KitchenAid oven while the F33 error is displayed?
The F33 fault is specific to the meat probe circuit and does not affect the main baking or broiling functions of the oven. You can generally continue using the oven for normal cooking as long as you do not attempt to use the probe temperature feature. However, you should address the fault before relying on the probe to avoid inaccurate temperature readings during cooking.
Will resetting the oven clear the F33 error code?
Resetting the oven by cutting power at the breaker for several minutes may temporarily clear the F33 code, but it will return if the underlying problem with the probe or jack has not been corrected. A reset is useful for confirming the fault is active and not a one-time glitch, but it is not a repair. The probe circuit resistance needs to be within specification for the fault to stay cleared.
How much does it cost to repair an F33 error on a KitchenAid oven?
If only the meat probe needs replacement, parts typically range from $20 to $60 depending on the model. A replacement probe jack or wiring harness can add $30 to $80 in parts. If you hire a technician to diagnose and complete the repair, expect to pay $100 to $250 or more total depending on labor rates in your area and whether multiple components need replacement.
