Maintain quiet, efficient airflow from your Lennox CBX25UH-036-1 air handler with genuine OEM replacement parts from Repair Clinic. The CBX25UH-036-1 is a 3-ton multi-position air handler in Lennox’s CBX25UH series, designed for energy efficiency and durable construction. The related CBX25UH-036-230-1, CBX25UH-036-230-10, and CBX25UH-036-230 are voltage and revision variants within the same general 3-ton platform; parts are often compatible across these designations, but always confirm using the product’s serial number and parts diagrams. Parts most frequently replaced include the evaporator coil, blower motor and wheel, fan relay and control board, and capacitor.

Lennox CBX25UH-036-1: 3-Ton Platform and CBX25UH-036-230 Voltage Variant Cross-Reference
The Lennox CBX25UH-036-1 is a 3-ton multi-position air handler; the related CBX25UH-036-230-1, CBX25UH-036-230-10, and CBX25UH-036-230 designations within the same series typically reflect voltage specifications and production revisions rather than fundamentally different platforms. Parts are often compatible with these related models, but always confirm using the product’s serial number and diagrams, since voltage-specific components like the transformer and certain control board configurations can differ between the -1 and -230 series designations. The CBX25UH-036-1 manual documents the blower speed tap settings and fan relay wiring. For diagnostic guidance, visit the Lennox air handler troubleshooting section.
CBX25UH-036-1 Component Failures and Diagnostic Sequences
CBX25UH-036-1 Evaporator Coil Replacement
The OEM CBX25UH-036 evaporator coil is available with installation resources to assist with the replacement process. A frosted or leaking coil should be diagnosed for airflow restriction (filter, blower capacitor, vents) before assuming refrigerant charge issues, since airflow problems are the more common root cause of coil frosting.
Lennox CBX25UH-036-1 Blower Motor and Wheel Service
The blower motor and wheel circulate conditioned air through the duct system. Test the capacitor before condemning the motor for any reduced airflow complaint; capacitor replacement is significantly less costly and resolves a meaningful proportion of airflow issues.
CBX25UH-036-1 and CBX25UH-036-230 Series Cross-Reference
Parts are often compatible with related models such as CBX25UH-036-230-1, CBX25UH-036-230-10, and CBX25UH-036-230. Always confirm using the product’s serial number and diagrams before ordering across these voltage or revision variant designations.
CBX25UH-036-1 Drain Pan and Float Switch Service
The float switch shuts down the CBX25UH-036-1 when the condensate drain backs up. Clear the drain line completely before resetting the float switch to prevent immediate repeat shutdown.
