A Lochinvar 100145023 Blower Motor Assembly circulates combustion air to maintain steady airflow and dependable performance when the machine is running.
The blower motor assembly produces the airflow needed for combustion, allowing the heating and cooling unit to maintain proper burner operation and steady performance. Its 115V configuration and assembly design matter because they support reliable air movement, fit and electrical compatibility within the HVAC system.
The blower motor assembly may be approaching replacement if the unit shows weak combustion airflow, inconsistent ignition, unusual shutdowns or reduced overall performance. Common indicators include unusual noise, vibration, overheating, visible wear or debris buildup and you might notice environmental signs such as excess dust, moisture exposure or heat stress that could affect operation.
