Key Features
- Official OEM Inducer Motor Assembly for Lennox HVAC equipment
- Listed as replacing: 80M5201
Compatibility & Applications
- Listed for Lennox HVAC equipment (the product page does not specify models or series).
- Must only be used where the manufacturer specifies this exact part number: 80M52 (confirm by unit model/serial and the unit's parts list/service literature).
Installation & Operation Notes
- Installation and service must be performed by a licensed professional HVAC installer (or equivalent) / service agency / gas supplier, per Lennox service literature.
- Use the unit's service/installation manual and wiring diagram for the correct procedure and checkout steps (Lennox provides product literature lookup by model number).
- Follow manufacturer safety practices referenced in Lennox documentation, including lockout/tagout, disconnecting electrical power, allowing time for internal electrical components to discharge, using caution around sharp sheet metal edges, and keeping hands/tools away from moving parts.
Maintenance & Troubleshooting
- Lennox documentation describes the combustion air inducer as operating during heating, including a pre-purge before ignition and post-purge after the gas valve closes, and being monitored by a pressure switch used to prove inducer operation.
- Troubleshooting context typically includes no-heat/failed ignition sequence conditions where the inducer cannot establish proper draft, or abnormal inducer noise (whining) indicating wear.
- Lennox guidance indicates that if draft/pressure conditions are not met (such as with a flue obstruction), the pressure switch opens and the control de-energizes the gas valve to prevent burner operation - diagnostics should follow the unit's service literature before replacing parts.
