Sporlan 310678 Coil 321702-401 Most ECM blower motor failures

Most ECM blower motor failures are caused by high static pressure (dirty filters or undersized ductwork) which forces the module to draw excessive amperage

and low speed taps connected to the control board

This genuine OEM furnace technical part is engineered for a critical 160-180F temperature range

ensuring a precise fit and reliable performance within your gas combustion systems

typically found in hot water heating boilers
