Dacor Range Oven Cooktop Error Code L60

The L60 error code on a Dacor range or oven indicates a fault with the cooling fan assigned to the lower oven cavity. This fan is responsible for circulating air around the oven's control electronics and structural components during and after cooking cycles, preventing heat-related damage to sensitive parts. When the control detects that the fan is operating below the expected speed threshold, has stopped entirely, or is unable to move air effectively, it triggers L60 to alert the technician to a cooling system problem.

The most common causes fall into three categories: mechanical failure of the fan motor itself, physical obstructions blocking the fan blades or airflow path, and electrical supply issues that result in insufficient voltage or current reaching the motor. A fan running at low speed rather than stopping completely can be especially difficult to diagnose by ear alone, so verifying rotational speed and current draw with a multimeter or clamp meter is the preferred approach. Blocked vents or debris accumulation behind the oven can also restrict airflow enough to trigger the fault even when the motor is functioning correctly.

Diagnostic work should begin by confirming the fan physically spins freely without obstruction, then checking that the motor receives proper voltage from the control board during operation. If voltage is present but the motor runs slowly or not at all, the motor itself is the likely failed component. If voltage is absent, the wiring harness and control board output should be inspected for damage or a failed relay.
