Hisense Range Error Code Err 010

Err 010 on a Hisense range indicates a self-clean heat-up failure. During the self-clean cycle, the oven must reach a very high target temperature within a defined time window. If the control board does not detect that the set temperature has been achieved within that window, it triggers Err 010 and aborts the cycle. The PT1000 sensor is the resistive temperature sensor responsible for reporting oven cavity temperature to the control board. A PT1000 sensor has a nominal resistance of 1000 ohms at 0 degrees Celsius, and its resistance increases predictably with temperature. If the sensor is faulty or reading incorrectly, the board may never confirm that the target temperature has been reached, even if the oven is heating normally.

The first diagnostic step is to disconnect the PT1000 sensor from the oven cavity and leave it at ambient room temperature, then attempt to run the self-clean function. This isolates whether the fault lies with the sensor itself or with other heating components. If the self-clean cycle runs without triggering Err 010 when the sensor is removed, the sensor is likely providing an out-of-range or erratic resistance reading that causes the control board to believe adequate temperature was never achieved. If the error persists with the sensor disconnected, the issue likely involves the bake or broil heating element, the control board, or wiring faults in the heating circuit that prevent the oven from physically generating sufficient heat.
