Hisense Range Error Code Err 008

Err 008 means the range has detected that the power board temperature has exceeded 230°F (100°C) based on a reading from the NTC thermistor mounted on the power board. As a safety response, the appliance immediately stops all oven functions until the condition is resolved. The fault may indicate actual board overheating or a failed NTC sensor sending a false high-temperature signal.

No. When Err 008 is active, the range has already disabled all oven functions as a safety precaution, and you should not attempt to override or bypass this shutdown. Continued operation with a genuinely overheating power board could cause component damage or create a fire hazard. Do not use the appliance until the fault has been properly diagnosed and repaired.

Repair costs vary depending on the root cause. If only the NTC thermistor or individual resistors need replacement, parts costs are typically modest, generally in the range of $10 to $50 for components. If the entire power board requires replacement, parts alone can range from $80 to $250 or more, and adding professional labor will increase the total. Getting a diagnostic from a technician first can help determine whether a targeted repair or full board replacement is needed.

Some steps, such as clearing obstructions from ventilation areas and inspecting wiring connections to the NTC sensor, can be performed by a knowledgeable DIYer. However, diagnosing failed resistors R100 and R145 with a heating gun or testing the NTC sensor's resistance output requires comfort working with electronics and live appliance components. If the power board itself needs replacement, a qualified technician is strongly recommended.

A power reset by unplugging the range or cycling the breaker may temporarily clear the error code, but the fault will return if the underlying cause has not been corrected. If the NTC sensor is damaged or the power board is genuinely overheating, the code will reappear as soon as the board reaches operating temperature again. A reset alone is not a fix.
