Hisense Range Error Code Err 002

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.

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.

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.

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.

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.
