🛠️ HVAC Depot Pro Tip: The "Blower Wheel" Check & G40UH Note

Before installing your new 69M79 motor, always inspect the existing blower wheel for dust buildup or imbalance. A dirty wheel is the leading cause of premature motor failure. If you are replacing an older motor in a G40UH series furnace (which may have used a 5/8" shaft), you must also purchase a compatible 1/2" bore blower wheel (Lennox Part # 45M36) and the new mounting bracket kit (Part # 73M85) to ensure proper and safe installation.
