Lennox Furnace and HVAC Replacement Parts

Lennox replacement parts can vary by equipment type, model number, series, fuel type, voltage, control configuration, and component application. This brand page may include service parts for compatible Lennox furnaces, air conditioners, heat pumps, air handlers, and related HVAC equipment. Common product types may include flame sensors, pressure switches, limit controls, capacitors, inducer assemblies, blower components, control kits, maintenance kits, gaskets, brackets, drain traps, conversion parts, and other repair components.

Find Lennox Parts by Model Number or Part Number

Many Lennox part searches begin with a model number, part number, parts list, or equipment diagram. If the original component has a readable label, compare the part number, electrical rating, size, connection type, and application with the product listing. For older Lennox furnace parts, model-specific components, or parts used across multiple equipment families, the exact model number and service documentation can help narrow the correct replacement.

Lennox Air Conditioner, Heat Pump, and Air Handler Parts

Lennox HVAC parts may also include components for cooling and heat pump systems, such as capacitors, condenser-related parts, blower modules, drain components, control parts, and electrical service components. Before selecting a replacement, compare the product details with the equipment data plate, existing part label, service manual, or parts diagram. Important details may include voltage, capacitance, horsepower, motor type, connector style, mounting style, and equipment application.

Confirm Compatibility Before Ordering

Use the exact Lennox part number whenever possible. If the part number is missing or difficult to read, compare the equipment model number, serial number, component specifications, dimensions, wiring connections, and installation application before purchasing. For ignition, gas, electrical, pressure, and temperature-control parts, confirm the replacement against the system documentation or consult a qualified HVAC professional before installation.
