What Err 002 means on a Hisense range

Err 002 on a Hisense range indicates a meat probe circuit failure, specifically a short circuit condition detected at the meat probe socket. The oven's control system continuously monitors the resistance signal from the meat probe input. When the resistance at the probe socket drops below a threshold consistent with a short circuit, the board flags this fault. The two primary hardware sources are a shorted meat probe socket on the range itself or a damaged power board and user interface (PB/UI) assembly that is misreading or generating an incorrect signal on that circuit.

Diagnosing Err 002 follows a two-phase approach targeting the probe socket and connector K22 on the control board. The first phase is a short test: with the meat probe removed, technicians check for a short across the meat probe socket or directly across pins 1 and 3 of connector K22. Any measurable continuity or near-zero resistance at those points confirms a short in the socket wiring or the board itself. The second phase is an over-temperature simulation test: inserting a resistor below 500 Ohms into the meat probe socket, or placing it across pins 1 and 3 of K22, replicates a shorted probe signal and confirms the control board responds correctly to that input.

If the socket and wiring test clean with no short present, the fault typically points to the PB/UI assembly. A damaged control board may internally short the probe input circuit, triggering Err 002 even when no probe is connected. Resolving the error requires either repairing or replacing the meat probe socket and associated wiring, or replacing the PB/UI board if the socket checks out normal.

Common causes of Err 002

  1. 01

    Shorted meat probe socket

    Part replacement

    The probe socket contacts can short together due to moisture, food debris, or physical damage inside the socket. Inspect the socket for corrosion, residue buildup, or bent pins, and test for continuity across the two contacts with the probe removed.

  2. 02

    Damaged or faulty probe left connected

    Part replacement

    A meat probe with internal wire damage or a shorted tip can pull the socket circuit into a short condition. Remove the probe and check if the error clears, then test the probe resistance to confirm it is open rather than shorted.

  3. 03

    Wiring fault between socket and connector K22

    Wiring / connection

    The wire harness running from the probe socket to pins 1 and 3 of connector K22 on the control board can develop a short due to chafing, pinching, or heat exposure. Trace and inspect this harness segment for insulation damage.

  4. 04

    Damaged PB/UI control board

    Part replacement

    If the socket and all wiring test normal with no short detected, the power board or user interface board is likely the source. An internal failure on the board can create a false short condition on the probe input circuit, requiring board replacement.

Frequently asked questions about Err 002

What does Err 002 mean on a Hisense range?
Err 002 indicates the range has detected a short circuit on the meat probe input circuit. The control board monitors resistance at the meat probe socket, and when it sees a value consistent with a short, it triggers this fault. The problem can originate from the probe socket itself, the wiring to connector K22 on the board, or from an internal failure on the power board or user interface assembly.
Can I fix Err 002 myself on a Hisense range?
Some steps are DIY-friendly, such as removing the meat probe, inspecting the socket for debris or corrosion, and checking whether the error returns with the probe unplugged. Testing resistance across pins 1 and 3 of connector K22 requires a multimeter and basic electrical knowledge. Replacing a damaged socket harness or the PB/UI board is more involved and may be better suited to a technician if you are not comfortable working with appliance wiring.
Is it safe to use my Hisense range while Err 002 is displayed?
The error specifically affects the meat probe input circuit, so standard oven cooking and surface burner operation may still function. However, the probe-based temperature monitoring will not work correctly while the fault is active. It is best to resolve the underlying short before relying on any probe cooking functions, as the control board may not accurately monitor food temperature.
Will resetting the range clear the Err 002 code?
Resetting the range by cutting power at the breaker may temporarily clear the display, but the code will return if the underlying short circuit condition is still present. The fault is hardware-based, meaning the control board will re-detect the short on the probe circuit as soon as it powers back up and monitors that input. A reset alone is not a fix and should only be used as part of the diagnostic process.
How much does it cost to repair Err 002 on a Hisense range?
Repair cost depends on which component has failed. Replacing a meat probe socket or a short section of wiring harness is typically the least expensive fix, with parts generally in the range of $15 to $60 plus any labor. If the PB/UI control board requires replacement, parts alone can run from $80 to $250 or more depending on the model, with additional labor costs if a technician performs the repair.
