Ao Smith 100271839 RG128 Blower Assembly Kit

Product Description

The AO SMITH 100271839 is a blower assembly kit for the RG128 series, designed as a direct OEM-style replacement component for water heater systems. The blower assembly moves combustion air through the burner and heat exchanger, maintaining proper draft and combustion efficiency. This kit does not include a pressure port, which is an important distinction for installations where the pressure sensing function is handled by a separate component or is not required. Licensed plumbers and HVAC technicians typically handle this replacement as part of a combustion system service.

This blower assembly kit is intended for use in residential water heater applications utilizing the RG128 series platform. It is suited for installations where the existing blower has failed or degraded, causing ignition faults, draft errors, or inadequate combustion airflow. The absence of a pressure port on this assembly makes it specific to configurations that do not route pressure sensing through the blower housing. Technicians should verify the existing unit's pressure port configuration before ordering to confirm this is the correct assembly variant.
