71516 on a Lennox air-conditioner resolves to the central air conditioning condenser fan motor replacement problem. Lennox parts typically run ×1.35 against the mainstream baseline (Lennox 'uses proprietary parts that only Lennox dealers can source.' A direct brand comparison found a blower-motor replacement running $2,400-$2,500 installed on Lennox vs $600-$1,200 on Carrier, with Lennox parts needing to be special-ordered direct from the factory (2-4 week wait) versus same-day local-supplier availability for Carrier parts.), and the ranges below already include it.
