Kenmore Range Error Code E66

E66 on a Kenmore range means the cooktop control board has detected a fault condition associated with one of the cooking zone pairs. The control system monitors paired burner zones for proper electrical behavior, and when something falls outside expected parameters, it triggers this code and disables the cooktop. The fault can originate from a failed relay, a bad heating element, a wiring issue, or the control board itself.

You should not attempt to operate the cooktop while E66 is active. The code indicates the control system has identified a fault in a cooking zone pair and has interrupted operation for that reason. Continuing to use the cooktop before the fault is diagnosed and resolved could risk further component damage or an unsafe operating condition.

A basic soft reset by pressing STOP and cycling the breaker is a reasonable first step for any homeowner. Beyond that, diagnosing E66 involves accessing the cooktop control board and zone wiring, which exposes high-voltage components and should only be attempted by someone comfortable working with appliance electrical systems. If the code recurs after a reset, calling a qualified technician or reaching Kenmore support at 1-800-4-MY-HOME is the recommended path forward.

Pressing the STOP key may clear the display, and cycling power at the circuit breaker can sometimes fully reset the control board. If the E66 code was caused by a transient voltage event, the reset may be all that is needed. However, if an underlying component has failed, the code will return after the reset and further repair will be necessary.

Repair costs vary depending on which component has failed. A wiring harness inspection and repair by a technician might run in the range of $100 to $200 for labor alone. Replacing a cooktop control board typically costs between $150 and $400 depending on the specific board required and labor rates in your area. A single failed heating element is generally less expensive to replace than the control board.
