Lennox 45C51 4 Blade Fan 24" DIA 1/2" Bore

Thermostatic expansion valves are an integral part of your refrigeration unit. They are responsible for ensuring the right dosage of refrigerant is entering the cooling coil to ensure maximum efficiency in the air conditioning of the system.    These special expansion valves come with a temperature sensor that is mounted at the end of the evaporator coil. They incorporate signals from this sensor to maintain the required temperature of the HVAC system. The thermostatic expansion valve works like a precision device that can regulate the measurements of the liquid refrigerant that flows into the evaporator of your system. This regulation in the flow of the refrigerant is essential to prevent the reverse flow of the refrigerant into the compressor of your system.    Through this mechanism, the thermostatic expansion valve successfully separates the high and low pressure sides of the refrigeration/air conditioning system. The liquid refrigerant enters the expansion ...

Regularly inspect the fan blade for dirt buildup, cracks, or imbalance, and clean them to maintain airflow efficiency. Check the bore and mounting for tightness and alignment. Lubricate related motor components if applicable and ensure power is disconnected before servicing for safety.

• Blade imbalance causing vibration or noise.
• Bent or damaged blades reducing airflow efficiency.
• Loose bore fit leading to improper rotation.
• Excessive wear causing wobbling or instability.
• Corrosion or buildup affecting performance.
