Lochinvar L100318771 Combustion Blower Motor Kit NKC199

Product Description

The LOCHINVAR L100318771 is a genuine OEM combustion blower motor kit designed for use in Lochinvar water heating equipment. The combustion blower draws in combustion air and exhausts flue gases, making it a critical component in the safe and efficient operation of the appliance. This kit replaces the factory blower assembly and is rated for 120 volts at 50/60 Hz, making it compatible with standard North American electrical supply. It is intended for installation by licensed HVAC or plumbing technicians familiar with commercial water heating systems.

This combustion blower motor kit is designed specifically for the Lochinvar NKC199 model. It serves as a direct OEM replacement in residential or light commercial water heating applications where the original blower motor has failed or is showing signs of wear such as excessive noise, reduced airflow, or failure to start. Proper combustion airflow is essential for safe burner operation, and a failing blower can trigger lockout conditions or combustion faults on the control board.
