Hisense Range Error Code Err 015

Err 015 indicates a zero-cross detection failure on the power board of your Hisense range. The zero-cross signal is used by the control board to time oven functions, and when it is absent or corrupted, all oven operations shut down. The fault points to either a failed zero-cross circuit on the power board or physical damage to the board itself.

No. When Err 015 is active, the range disables all oven functions as a protective measure because the control board cannot properly time or manage heating operations without the zero-cross signal. Attempting to bypass or ignore this fault and continue using the oven is not safe and could cause uncontrolled heating behavior.

Repair costs depend on whether the issue is a wiring connection problem or a failed power board. A wiring fix may involve minimal cost if no parts are needed. Power board replacement typically costs in the range of $150 to $400 or more depending on parts availability and labor rates in your area. Getting a diagnostic assessment from a technician before committing to a repair is advisable.

Some basic checks, such as inspecting the OP1 pin 4 connector for loose or corroded contacts, can be performed by a knowledgeable DIYer after disconnecting power to the range. However, diagnosing and replacing the power board involves working with high-voltage AC components, which carries serious shock risk. If you are not experienced with appliance electronics, this repair is best left to a qualified technician.

A power reset by unplugging the range or cycling the circuit breaker for a few minutes may temporarily clear the display, but Err 015 will return if the underlying power board fault has not been repaired. The zero-cross failure is a hardware issue, and no amount of resetting will resolve a failed circuit or damaged board.
